Data Provider | NOAA Office of Satellite and Product Operations (OSPO) uses the GCOM-W1 AMSR-2 Algorithm Software Processor (GAASP) which takes the full orbital JAXA L1B data via NASA, applies brightness temperature bias corrections, assigns an RFI flag, performs internal reformatting, and then generates L2 products from the NOAA Operational GCOM-W1 AMSR-2 Products System Algorithm (NOGAPS). NOAA CoastWatch obtains L2 from OSPO and generates L3 daily merged (composite) and maps to polar stereographic projection for routine distribution. |
