Support for Near Real Time GCOM-W1 AMSR2 Algorithm Software Package (GAASP) Level-2 Products Via Direct Broadcast Using the Community Satellite
Presentation 1530-1600. The Cooperative Institute for Meteorological Satellite Studies (CIMSS) has a long history of supporting the Direct Broadcast (DB) community for various low-Earth-orbit (LEO) sensors, previously with the International MODIS/AIRS Processing Package (IMAPP) for the NASA EOS polar orbiters Terra and Aqua, and currently with the Community Satellite Processing Package (CSPP) for the NOAA polar orbiters Suomi-NPP and NOAA-20, EUMETSAT polar orbiters Metop-A, Metop-B and Metop-C, and others.
The Community Satellite Processing Package (CSPP) now supports the generation of level-2 products using the NOAA/NESDIS/STAR Global Change Observation Mission-Water (GCOM-W1) AMSR2 Algorithm Software Package (GAASP) in support of direct broadcast for JAXA’s GCOM-W1 satellite. GAASP generates Science Data Record (SDR) and Environmental Data Record (EDR) data products for near real-time users from the GCOM-W1 data stream. GAASP level-1 and level-2 products supported by CSPP-GAASP include bias-corrected Microwave Brightness Temperatures (MBT), Precipitation (land and ocean rain rates), GHR Sea Surface Temperature (SST), Sea Surface Winds (SSW), Total Precipitable Water (TPW), Cloud Liquid Water (CLW), Soil Moisture, Surface Type, Snow Cover, Snow Depth, Snow Water Equivalent, and Sea Ice.
GAASP (currently version v2r2) has been adapted to run in a near-real time environment for direct broadcast users in the CSPP-GAASP package, which provides a convenient command-line interface allowing the generation of one or more of the available products, for single or multiple SDR input files. CSPP-GAASP includes binary executable files, wrapper scripts and supporting static data files. Ingest and staging of any required dynamic ancillary data is handled automatically by CSPP-GAASP. A separate test data package can be downloaded for verifying a successful installation.
