| Release of ROM SAF atmospheric gridded products generated from Sentinel-6 radio occultation observations |
| DATE: 2022-03-14 13:53 TYPE: DATA |
| Description |
| Dear ROM SAF DATA User Issued : 2022-03-14 13:50 UTC The ROM SAF is pleased to announce the release of operational products containing monthly gridded atmospheric temperature, humidity, pressure, refractivity and bending angles 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: - bending angle, refractivity (Level 3, product identifiers GRM-123, GRM-124) - dry temperature, dry pressure, geopotential height (Level 3, GRM-128, GRM-129, GRM-127) - temperature, humidity (Level 3, GRM-125, GRM-126) - tropopause height (Level 3, GRM-195) All products are released with status "operational", with the exception of the tropopause height which has "pre-operational" status until validation is completed successfully. The products are provided in netCDF files and include monthly standard deviations, sampling errors, and uncertainty estimates in addition the the monthly means. Access to products and user documentation is available (after registration) at the ROM SAF Product Archive (https://www.romsaf.org/product_archive.php) The released ROM SAF Sentinel-6 Level 3 gridded monthly-mean products starts with December 2021 and the products will be released monthly about three weeks after end of a month. NTC products are generated with similar algorithms as used for the ROM SAF Offline products based on the GRAS sensors onboard the Metop satellites. Kind regards The ROM SAF Team |
