| Fwd: Release of ROM SAF atmospheric profile products generated from Sentinel-6 radio occultation observations |
| DATE: 2021-12-21 12:56 TYPE: DATA |
| Description |
| Dear ROM SAF Data User Issued : 2021-12-21 12:55 UTC We had some problems sending the user notification below and consequently it did not reach all ROM SAF data users. We apologize for the inconvenience. Kind regards The ROM SAF Team ------------------------------------------------------------------------------------------------------- Dear ROM SAF DATA User Issued : 2021-12-16 14:00 UTC The ROM SAF is pleased to announce the release of operational products containing vertical profiles of atmospheric pressure, temperature, humidity and refractivity based on radio occultation (RO) measurements onboard the Sentinel-6 Michael Freilich satellite. The ROM SAF Sentinel-6 products are based on bending angle data generated at the EUMETSAT Secretariat derived from measurements from the NASA GNSS-RO instrument flying onboard Sentinel-6. The purpose of the released ROM SAF products is to provide a stable and quality controlled RO dataset for non-time critical (NTC) applications. The ROM SAF Sentinel-6 NTC products contain the following geophysical parameters: - Refractivity, dry temperature (Level 2A, product identifiers GRM-117, GRM-122) - Temperature, humidity, pressure (Level 2B, product identifiers GRM-118, GRM-119, GRM-120) - Surface pressure (Level 2C, product identifier GRM-121) All products are released with status "operational", with the exception of the temperature (GRM-118) and humidity (GRM-119) profiles. They have "pre-operational" status until validation is completed successfully. The products are formatted as NetCDF files with a subset of the products formatted as BUFR. In addition, the files include a copy of the EUMETSAT Secretariat Level 1B NTC bending angle. Access to products and user documentation is available (after registration) at the ROM SAF Product Archive (http://www.romsaf.org/product_archive.php) More details are available here: https://www.romsaf.org/previous_news.php#December16-21_168 (see also the user message about Sentinel-6 from the EUMETSAT Secretariat: https://www.eumetsat.int/new-sentinel-6-michael-freilich-products, 17 Nov 2021). The released ROM SAF Sentinel-6 products starts with 14 November 2021 and new products will be released regularly once a day about two weeks after sensing time. NTC products are generated with similar algorithms as used for the ROM SAF Offline products based on the GRAS sensors onboard the Metop Satellites. Additionally, the ROM SAF will produce Sentinel-6 gridded products every month. The gridded products (Level 3) are calculated as monthly means from Level 1B and Level 2 profile products. The Level 3 products will be available shortly after the end of a completed month. The release of the first month of Level 3 products will cover December 2021 and its release will be announced in a separate user announcement. Kind regards The ROM SAF Team |
