SUBJECT:  Amended: Implementation of new METAR and TAF
          collectives for the United States, for International
          Distribution, effective December 8, 2016 

NOTE:     The following changes have no impact on NOAA Weather
          Wire Service subscribers

Amended to change effective date to December 8, 2016

Effective December 8, 2016, at 1800 Coordinated Universal Time 
(UTC), the following collectives will be added to the 
Washington OPMET databank for international distribution. 

SAUS21 KWBC  SPUS21 KWBC  FTUS21 KWBC
SAUS22 KWBC  SPUS22 KWBC  FTUS22 KWBC
SAUS23 KWBC  SPUS23 KWBC  FTUS23 KWBC
SAUS24 KWBC  SPUS24 KWBC  FTUS24 KWBC
SAUS25 KWBC  SPUS25 KWBC  FTUS25 KWBC

These collectives will be implemented in response to FAA 
requirements that all US METARs used by international carriers 
must contain the remarks section of the METAR. Under current 
practice, the METAR with remark is not sent out 
internationally. In addition, the legacy collectives that do 
not comply with new FAA requirements will be discontinued. 
These collectives are noted below. 

Additionally the United States will now include all U.S. TAFs 
and their associated METARs per the request from the 
International Airline and Transportation Association (IATA). In 
the past, only 450 TAFs and METARs were distributed.  

The following legacy METAR and TAFs collectives will be 
discontinued after January 15, 2017:

SAUS71 KWBC SPUS71 KWBC FTUS71 KWBC
SAUS72 KWBC SPUS72 KWBC FTUS72 KWBC
SAUS73 KWBC SPUS73 KWBC FTUS73 KWBC
SAUS74 KWBC SPUS74 KWBC FTUS74 KWBC
SAUS75 KWBC SPUS75 KWBC FTUS75 KWBC
SAUS90 KWBC SPUS90 KWBC FTUS90 KWBC

This change will be transparent to WIFS users. WIFS users can 
log into the WIFS testbed to view the additional TAF and 
METARs, see (password protected): 

http://testbed.aviationweather.gov/wifs/data/

Note that users of WIFS will no longer be able to retrieve 
METAR without Remarks, effective November 30 all U.S. METAR 
reports on WIFS will have the Remarks Section.

Regional OPMET data centers and other users that receive the 
new collectives directly can test them here after September 14:

tgftp.nws.noaa.gov/SL.us008001/ST.opnt/DF.an/DC.sflnd/DS.icaot

Domestic US collectives such as FTUS80 KWBC and SAUS80 KWBC 
among others will not be affected. This change only affects US 
METAR and TAF for international distribution.
