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):

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.
