Weather Service Modernization Criteria
AGENCY: National Weather Service, National Oceanic and Atmospheric
Administration, Department of Commerce.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: In accordance with the Weather Service Modernization Act, 15
U.S.C. 313n. (the Act), the National Weather Service (NWS) is
publishing an amendment to its criteria for modernization actions
requiring certification. This amendment adds criteria unique to
automating a field office to ensure that automation actions will not
result in any degradation of service. Automating a field office occurs
after automated surface observing system (ASOS) equipment is installed
and commissioned at a field office and the News employees that were
performing surface observations at that office are removed or
reassigned.
EFFECTIVE DATE: July 31, 1996.
ADDRESSES: Requests for copies of documents stated in the preamble as
being available upon request should be sent to Julie Scanlon, NOAA/NWS,
SSMC2, Room 9332, 1325 East-West Highway, Silver Spring, Maryland
20910.
FOR FURTHER INFORMATION CONTACT:
Nicholas Scheller, 301-713-0454.
SUPPLEMENTARY INFORMATION: On May 2, 1996, the NWS published, for
comment, proposed modernization criteria unique to automating a field
office (see 61 FR 19594). In significant part, the proposed criteria
embodied the four levels of service contained in the Federal Aviation
Administration's (FAA) Weather Observation Service Standards for level
A, B, C and D airports (see 61 FR 32887). After consideration of the
public comments that were received and, after consultation with the
National Research Council's (NRC) NWS Modernization Committee and the
Modernization Transition Committee (MTC), the NWS is now establishing
the final modernization criteria for automating a field office only at
service level A, B and C airports. Establishment of final modernization
criteria for automating a field office at service level D airports is
being deferred pending further consultation with the MTC.
Consultation with the NRC's NWS Modernization Committee was
completed on June 10, 1996. During consultation with the MTC on June
27, 1996, the MTC offered the following:
The Modernization Transition Committee (MTC) has reviewed the
comments received in response to the notice in the Federal Register,
considered information provided through presentations and reports,
and thoroughly discussed the issue of level of service provided by
the modernized weather service as compared to on-site observers,
with the following conclusion:
The MTC approves the proposed automation criteria for airport
service level A, B and C airports believing that there will be no
degradation of service associated with these certifications.
However, the Committee has drawn no conclusion about degradation of
service at D service level airports that previously had an NWS
observer. The Committee will address the remaining portion of D
service level airports at their next scheduled meeting.
Peter R. Leavitt
Chair, Modernization Transition Committee.
A total of 44 public comments were received with postmarks by the
closing date for comments. Six additional comments were received with
postmarks after the closing date. The issues raised in these late
comments however, were similar to others raised in the timely comments.
All comments received were considered and are included in the numerical
totals below. The issues and concerns raised in the comments and the
Government's response follows. Most comments have to do with leaving
ASOS unattended, either generally or at specific airports. The number
of issues/concerns exceeds the total number of comments, since multiple
issues/concerns were raised in some comments. A list of persons
submitting comments is also included.
A. Comments related to leaving ASOS unattended:
1. Comment: 33 comments stated that service level D was inadequate
for their particular airport.
Response: Establishment of final criteria for service level D
airports has been deferred. The NWS will not take any action to
automate field offices at service level D airports, pending further
consultation with the MTC. Accordingly, the 27 airports proposed for
service level D have been deleted from Appendix B.
2. Comment: 10 comments expressed the following concerns about
ASOS: (a) ASOS can not be left in the unattended mode; (b) a human
presence is required at all ASOS sites; and (c) ASOS observation is
sometimes unrepresentative of actual conditions.
Response: Development and testing of automated weather observing
[[Page 39863]]
equipment has been in progress for nearly 20 years. Numerous studies
and evaluations were conducted on automated observation systems
beginning in the 1970s which included systems and technology similar to
that of ASOS. Assessments of representativeness were made by comparing
automated reports, specifically, ceiling and visibility to the human
observer. As a result of the more than two decades of development and
testing, ASOS has evolved into a highly accurate, consistent, and
reliable complement to meteorological observations.
The most recent testing effort was the ASOS Aviation Demonstration
that was carried out jointly by the NWS, the FAA, and the aviation
industry, from February 15, 1995 through August 15, 1995. During this
Demonstration, NWS observers were asked to record those cases when ASOS
observations did not represent the true meteorological situation. Based
on reports supplied by NWS observers, ASOS was found to report the
correct individual weather parameters at least 98% of the time under
all conditions combined.
From the beginning, ASOS was never intended to be the sole source
of surface weather data. ASOS data will be supplemented by products
derived from other remote automated systems including satellite, radar,
and lightning networks. Efforts to develop and refine these new sensors
and additional data products are underway. However, ASOS observations
will continue to be ``augmented'' by human observers, at those sites
required by the aviation community, until these additional sensors and
data products are available, and their use is fully understood.
The strength of ASOS is not that it is ``better'' than the
observer, but that the sensor suite can be put in the area most
sensitive to the weather that the pilot needs, that multiple sensors
can be used at those sites where required, and that ASOS observations
are consistent from station to station, day to night, and continuous 24
hours a day.
3. Comment: One comment stated that the FAA, NWS, aviation
community agreement on service level D included a requirement for both
freezing rain and lightning detection sensors.
Response: The deployment of freezing rain sensors as part of the
ASOS is underway. Funding has been allocated for acquisition of over
400 sensors. The freezing rain software and hardware upgrade deployment
will be deployed at NWS sites by winter 1996/1997.
Automated thunderstorm detection capability is presently being
acquired as part of the Automated Weather Observing System (AWOS) Data
Acquisition System and will provide an automated thunderstorm report in
the METAR format from the ASOS at all level A, B, C and D sites.
Deployment of this automated thunderstorm reporting capability will
begin in June 1997. Until that time, thunderstorms will be detected and
reported manually at all sites with implemented level A, B and C
Weather Observation Service Standards.
Pending automation of freezing rain and thunderstorm detection and
reporting, neither of these parameters will be manually augmented at
level D sites. This policy was clearly established during the extensive
discussions on Weather Observation Service Standards with the aviation
industry during the last 18 months.
4. Comment: Three comments regarding Astoria, Oregon, proposed as a
D level airport, requested that local public hearings be held before
ASOS implementation.
Response: The ASOS has already been ``implemented'' at Astoria,
Oregon to the extent that it was commissioned on March 1, 1993. The
second stage of implementation will be to ``automate'' this office and
the Weather Service Modernization Act already provides for extensive
public input at this stage in several ways. Criteria by which these
actions will be certified are made available for public comment through
publication in the Federal Register. Two independent committees are
consulted during the establishment of final criteria: The National
Research Council's NWS Modernization Committee which is composed of
scientific and technical experts, and the Modernization Transition
Committee (MTC) which represents users of weather services. During
these consultations, both Committees are apprised of all public
comments received. There are two other opportunities for public input
during the certification process. Each proposed certification is
published in the Federal Register for a 60-day public comment period.
The MTC is apprised of all public comments received and has the
opportunity to recommend a course of action to the Secretary of
Commerce with regard to the final certification of ``no degradation of
service''. Finally, the MTC is a Federal advisory committee and as
such, all MTC meetings are open to the public. As part of the
consultation with the MTC on certifications and preceding deliberations
by the MTC, there is a public comment period during which the public
may address the MTC.
B. Other comments:
1. Comment: Six comments were concerned that there might be a delay
in implementing service levels A and B due to lack of funds and that
the delay would result in a degradation of service. One comment
requested that a ban on further ASOS commissionings be instituted until
funds are available to implement service levels A and B.
Response: The FAA will fund full implementation of the Weather
Observation Service Standards, including all level A and B airports.
Accordingly, NWS has eliminated any funding contingency from criterion
4a.
2. Comment: Two comments indicated that the list of airports
published in the May 2 Federal Register notice was incomplete and/or
confusing.
Response: The airports in the May 2, 1996 Federal Register notice
list were the 143 ``field offices'' which require a certification prior
to automation under the Weather Service Modernization Act. The Act
defines a field office as a Weather Service Office (WSO) or a Weather
Service Forecast Office (WSFO). Beyond these 143 locations, there are
additional airports where NWS has surface observing responsibility that
either: (1) Are not field offices--Weather Service Meteorological
Observatories (WSMOs) and Weather Service Contract Meteorological
Observatories (WSCMOs); or (2) are field offices, but NWS will continue
to perform surface observing functions. There are also a number of
airports where the FAA has surface observing responsibility. On June
25, 1996, the FAA published in the Federal Register its Weather
Observation Service Standards and a more comprehensive list of all
airports where either NWS or FAA has had surface observing
responsibility (see 61 FR 32887). Not included in this June 25 notice
are the so called ``expansion sites'', which are sites that have not
had a Federally sponsored surface observation.
3. Comment: One comment stated that automation, as proposed, will
have an adverse impact on snowfall records.
Response: Snowfall data will continue to be recorded at 46 Weather
Forecast Offices (WFO) co-located with ASOS as well as new snowfall
climatologies will commence at 73 WFOs during the 1996-1997 winter
season. In addition, snow-depth observations will continue at 22 Tower
Level 5 airports next winter season. In addition, along the Washington
and Oregon coastline, there are over 30 NWS cooperative observer (COOP)
climate stations that will continue to report daily snowfall, snow
depth, and accurate precipitation amounts for climatologists. The
primary
[[Page 39864]]
purpose of this volunteer network is the taking of long-term climate
records. The NWS is now in the process of implementing a system that
will allow these observations to be disseminated to external users
once-a-day in near real-time.
Washington and Oregon contain about one dozen first-order airport
stations that historically reported snowfall information that will no
longer be available. However, data from COOP climate stations in both
states are actually considered to be the data of choice by most
climate-change researchers. The COOPs are located off airports at
locations where people live. COOPs with decades of records are found in
the temperate rain forests, Olympic mountains, and other ecologically
sensitive areas.
The volunteer COOP network will continue to provide high-quality
climate data for NWS and external users. The NWS is even considering
opening new COOP stations in areas where observations are scarce with
snowfall information unavailable and whereby no current COOP is located
in the surrounding vicinity.
In addition, the Supplementary Data Program (see 60 FR 64020),
became operational on October 1, 1995 at 119 WFOs, where staffing and
equipment permits. This includes the providing of event driven
supplementary data observations (i.e., ice pellets, snow increase
rapidly, size of hailstones) and routinely scheduled supplementary
climatological data (i.e., depth of new snow, duration of sunshine,
water equivalent of snow on ground).
4. Comment: One comment expressed concerns with ASOS's inability to
detect clouds above 12,000 feet, use of ``fair'' for sky conditions
when ASOS reports ``CLR below 12,000 ft.'', and ASOS not reporting
freezing rain.
Response: A few years ago, NOAA started generating a Satellite
Cloud Product (SCP) to complement ASOS above 12,000 ft. SCPs, generated
for a 50x50-km grid centered around ASOS sites, are available in
regional collectives through the Family of Services with the following
bulletin headings:
GOES-8
TCUS40 KWBC--Eastern US
TCUS41 KWBC--Central US
TCUS42 KWBC--Southern US
GOES-9
TCUS51 KWBC--Central US
TCUS52 KWBC--Southern US
TCUS53 KWBC--Western US
Among other things, the SCPs indicate the cloud category (CLR, SCT,
BKN, OVC) and the height of the cloud in 100's of feet.
NWS is sensitized to the ``FAIR'' issue and is working toward a
more representative depiction of sky conditions on the Hourly (State)
Weather Roundup (SWR). NWS sites which ``run'' the SWR can merge the
SCP data with the ASOS data, thereby producing a better combined sky
condition. Many NWS sites are already doing this and more will be doing
so in the future once SCPs are generated for all ASOS sites.
The issue of the ``FAIR'' on The Weather Channel (TWC) is a little
different. TWC gets its observational data from Weather Services
International (WSI) Corporation. WSI does not presently process NWS
SWRs. ``FAIR'' is a WSI term.
NWS has had discussions with both TWC and WSI about this issue.
Both are working on schemes to assimilate the SCP data, thereby making
a more representative sky condition. In lieu of utilizing the WSI
observational data stream, TWC is independently investigating the
feasibility of ``ingesting'' and displaying the NWS SWRs on their
``Weather on the 8's'' segment.
The concern about reporting of freezing rain is addressed in the
response to comment A3.
5. Comment: One comment stated that ASOS should be replaced by
METAR.
Response: The writer of this comment has misunderstood the
difference between METAR and ASOS.
The Aviation Routine Weather Report (METAR) does not replace ASOS.
ASOS is an automated and integrated group of sensors to collect surface
weather parameters.
METAR on the other hand is the reporting format in which the
weather elements are provided from the ASOS. Historically, there have
been two weather reporting formats. North American countries (United
States, Canada and Mexico) used a format referred to as a Surface
Aviation Observation (SAOP, and the rest of the world, with minor
differences, used a format called Aviation Routine Weather Report
(METAR) to report weather. For years discussions took place on
standardizing the reporting format. Agreement was reached in 1989 and
the resultant code, still referred to as METAR, represents a blend of
the existing SAO and METAR reports. Because countries were permitted to
file exceptions to the code format, not all METAR reports are
identical, and thus there will be slight differences among the codes.
Canada and Mexico have already implemented the METAR code format, and
the United States, in accordance with international agreements,
implemented the METAR code format on July 1, 1996.
6. Comment: One comment stated that the ASOS at Wheeling-Ohio
County Airport remains uncommissioned.
Response: The ASOS at Wheeling--Ohio County airport is an FAA-
sponsored ASOS and requires FAA long-line communications for
commissioning. Currently, plans are to install the communications lines
in the fall 1996 followed by commissioning in January/February 1997.
7. Comment: One comment stated that there is no radio transmission
from the ASOS at Marathon Airport (MTH), Florida.
Reponse: A ground-to-air radio was installed at Marathon in March
1994. Shortly after installation, radio frequency interference was
reported. That interference problem was corrected on May 14, 1996 and
the radio is now broadcasting.
8. Comment: Three comments raised concerns about specific public
forecast product, the quality of the forecasts, timeliness of NOAA
Weather Radio updates, elimination of the agricultural forecast program
and closure of the Astoria, Oregon Weather Service Office (WSO).
Response: These issues are not related to ASOS and/or automation
and are more appropriately addressed during the certification process
for actions involving the particular WSOs.

A. Classification Under Executive Order 12866
These regulations establish procedures and criteria for certifying
that certain actions to modernize NWS will not result in any
degradation of weather services to the affected service area. They will
not result in any direct or indirect economic impacts, and have been
determined not to be significant for purposes of E.O. 12866.
B. Regulatory Flexibility Act Analysis
These regulations set forth the criteria for certifying that
certain modernization actions will not result in a degradation of
service to the affected area. These criteria will be appended to the
Weather Service Modernization regulations. The Assistant General
Counsel for Legislation and Regulation of the Department of Commerce
has certified to the Chief Counsel for Advocacy of the Small Business
Administration when these criteria were proposed, that if adopted as
proposed, they will not have a significant economic impact on a
substantial number of small entities. These criteria are intended for
internal agency use, and the impact on small business entities will be
negligible. The proposed criteria do not directly affect ``small
government jurisdictions'' as defined by Pub. L. 96-354, the Regulatory
flexibility Act. Accordingly, no initial regulatory flexibility
analysis was prepared.
C. Paperwork Reduction Act of 1980
These regulations will impose no information collection
requirements of the type covered by Pub. L. 96-511, the Paperwork
Reduction Act of 1980.
D. Executive Order 12612
This rule does not contain policies with sufficient Federalism
implications to warrant preparation of a Federalism assessment under
Executive Order 12612.
E. National Environmental Policy Act
NOAA has concluded that issuance of this rule does not constitute a
major Federal action significantly affecting the quality of the human
environment. Therefore, an environmental impact statement is not
required. A programmatic Environmental Impact Statement (EIS) regarding
NEXRAD was prepared in November 1984, and an Environmental Assessment
to update the portion of the EIS dealing with the bioeffects of NEXRAD
non-ionizing radiation was issued in 1993.

Administrative practice and procedure, Certification,
Commissioning. Decommissioning, national Weather Service, Weather
service modernization.
Dated: July 26, 1996.
Elbert W. Friday, Jr.,
Assistant Administrator for Weather Services.
For the reasons set out in the preamble, 15 CFR part 946 is amended
as follows:
1. The authority citation for part 946 continues to read as
follows:
Authority: Title VII of Pub. L. 102-567, 106 Stat 4303 (15
U.S.C. 313n.)
2. Appendix A to part 946 is amended by adding a new Subsection (D)
under Section II. CRITERIA FOR MODERNIZATION ACTIONS REQUIRING
CERTIFICATION, to read as follows:
(D) Modernization Criteria Unique to Automation Certifications
1. Compliance with flight aviation rules (applies on airports
only): Consultation with the Federal Aviation Administration (FAA)
has verified that the weather services provided after the
commissioning of the relevant ASOS unit(s) will be in full
compliance with applicable Federal Aviation Regulations promulgated
by the FAA.
2. ASOS Commissioning: The relevant ASOS unit(s) have been
successfully commissioned in accordance with the criteria set forth
in section I.A.1 of Appendix A to the Weather Service Modernization
Regulations, 15 CFR part 946.
3. User Confirmation of Services: Any valid user complaints
related to actual system performance received since commissioning of
the ASOS have been satisfactorily resolved and the issues addressed
in the MIC's recommendation for certification.
4. Aviation Observation Requirement: At sites subject to
automation certification, all surface observations and reports
required for aviation services can be generated by an ASOS augmented
as necessary by non-NWS personnel.
a. The ASOS observation will be augmented/backed-up to the level
specified in Appendix B as described in the Summary Chart of the
FAA's Weather Observation Service Standards.
b. The transition checklist has been signed by the appropriate
Region Systems Operations Division Chief.
5. General Surface Observation Requirement: The total
observations available are adequate to support the required
inventory of services to users in the affected area. All necessary
hydrometeorological data and information are available through ASOS
as augmented in accordance with this section, through those elements
reported as supplementary data by the relevant Weather Forecast
Office(s), or through other complementary sources. The adequacy of
the total surface observation is addressed in the MIC's
recommendation for certification.
