Notification from ECMWF:

Upgrade of ECMWF Products on the GTS:
ECMWF has upgraded its products on the GTS. The spatial resolution for analysis and model data from the deterministic forecast system has been increased from a typical 2.5 x 2.5 degrees lat/lon to 0.5 x 0.5 degrees lat/lon. The products are available as global fields in FM92 - GRIB edition 2. The data is being inserted onto the GTS by our partners, the Deutscher Wetterdienst (DWD) in Germany and the Met Office in the UK.

The old products at the lower resolution will be available in parallel until the end of 2010. In order to avoid a clash of the bulletin designators between the old and new data the last character of the CCCC group for the higher resolution fields has been incremented by one character (i.e. ECMF becomes ECMG, ECMW becomes ECMX).
Further information about the upgraded products, including listings of the bulletin headers and a link to ECMWF's GRIB API software that can be used to decode the GRIB-2 data, can be found at: http://www.ecmwf.int/products/additional/index.html

Please note: all of these products are also available for ftp download via the Internet from this web site.

Notification from the Netherlands:

Dutch North Sea platforms, equipped with full AWS (final status):

Since 2006, The Netherlands (KNMI) has provided several North Sea platforms in the Dutch sector with AWS equipment. As from Monday 09 November 2009, one more North Sea station P11-B (06203-EHPG) is declared operational. This makes it a total of 13 fully automatically operating meteorological observation sites, hereby completing the KNMI implementation project.

All platforms or gas/oil riggs, equipped with a PWS (no PWS for 06252, 06320 and 06321), will produce AUTO SYNOP as well as AUTO METAR (for helicopter flight purposes) and AUTO KLIM (climatological reports, national use). All half-hourly AUTO METAR reports are included in one bulletin, explicitly devised for aviation observations in the Dutch North Sea sector: SANL33 EHDB.

Platform F3-FB-1: As of 09 November 2009, platform F3-FB-1 (06239) is producing observation data again, since it was declared meteorologically dormant at 6 January 2009.

As of 19 May 2009, level 1c BUFR encoded satellite sounding data from the global network of Regional ATOVS Retransmission Services (RARS) are transmitted over the GTS using a common GTS bulletin header structure and, when applicable, a common file name structure. The RARS network currently includes 30 operational stations and is expected to cover more than 76% of the globe’s surface by the end of 2009. It delivers ATOVS data (HIRS, AMSU-A, AMSU-B or MHS) from NOAA POES satellites, and from METOP when applicable, nominally within 30 minutes after acquisition. Details on current and planned RARS stations, coding and identification of RARS data, data access and monitoring, are provided on: http://www.wmo.int/pages/prog/sat/RARS.html and on the web pages of the regional RARS operators

Reference: WMO letter dated 1 October 2008 and Corrigendum to Supplement No 6

Notification from Canada:

With respect to METAR/SPECI: ICAO designated aviation authority in Canada, Transport Canada, has been provided with the corrigendum but does not envisage any changes to Canadian practices given that these corrections refer to practices that are not followed in Canada. Canada does not include runway condition in the METAR/SPECI and does not use either NDV or CAVOK (Canada has State Differences on file with ICAO on these matters). Canada has another State Difference on file to indicate that Canada continue to use SKC.

With respect to SYNOP: The corrigendum regarding SYNOP does not apply to Canada as they do not report cloud layers at automatic sites.
