Full earth images, if any, will not be disseminated. METEOSAT IODC 20 October 2009 09:28 UTC Meteosat-7 Gain Change* *There will be a Meteosat-7 IR gain change from 10 to 11 and WV gain change from 11 to 12. METOP and NOAA GLOBAL DATA SERVICE 22 October 2009 05:12 UTC - 09:11 UTC IASI External calibration. Data will be unavailable during this period. METOP AHRPT DIRECT READOUT For current information please see: http://oiswww.eumetsat.org/UNS/webapps/showData.do?type=17 FUTURE EVENTS For the Meteosat-8 and Meteosat-9 meteorological product generation, the following changes will be introduced on the 2nd November 2009:- The maximum size of the GTS bulletins shall be increased from 15 KB to 50 KB. - Within the Multi-sensor Precipitation Estimate (MPE) product generation the data from SSMI/S will be used in addition to SSM/I data, leading to an improved product coverage. - With respect to the GRIB products, the last two empty bytes in the header of the file before the GRIB data will be removed. - To the GRIB encoded divergence product (DIV) an additional field will be added: The wind speed field has been added (Parameter ID 15). - The surface type field in the AMV BUFR product will not any longer be set to undefined, but will adopt one of the following values: 0 for land surface, 1 for sea surface, 2 for coastal surface, 3 for missing information. In addition the treatment of the search area near the border of the processing mask close to 65 degrees has been improved, leading to more AMV derivations in the area between 62 and 65 degrees.
- To the BUFR encoded global instability (GII) product, the layer precipitable water for the following layers have been added: Surface - 850 hPa 850 - 500 hPa 500 hPa - Top of Atmosphere Test files for the affected GRIB and BUFR products are available on FTP : ftp://ftp.eumetsat.int/pub/EUM/out/OPS/User/Met_Product_Update_02-11-09/ The Meteosat-8 Rapid Scanning Service will be interrupted from 17 November 2009 until 17 December 2009 for the annual one month full earth scanning. Full earth scanning data (if any) will not be disseminated.* Contact Information for Further Information: *Please contact the EUMETSAT User Services Helpdesk Tel: +49 6151 807 366 Fax: +49 6151 807 379 Email: ops@xxxxxxxxxxxx www.eumetsat.int*
