AATSR Spatially Averaged Sea/Land Geophysical product (ATS_AR__2P) and Meteo product (ATS_MET_2P)
The Level 2 spatially averaged geophysical product (ATS_AR__2P) contains data at two different resolutions, and with respect to two different averaging schemes. Measurement data sets at resolutions of 0.5 by 0.5 degrees and 10 by 10 arcmin with respect to a latitude/longitude grid, plus other data sets averaged over equal area cells of 50 by 50 km and 17 by 17 km aligned with the satellite ground track.
Both top-of-atmosphere and surface data sets are provided. The surface temperature data sets provide, for sea cells, nadir and dual view sea surface temperatures, and for land cells, land surface temperature and NDVI. Cloud data is also included. No ADS are included in the AST product; auxiliary data is contained within the MDS. The data sets of the AST product are arranged by surface type and resolution.
A subset of the spatially averaged geophysical product is provided as the AATSR Meteo product (ATS_MET_2P). Originally intended as a fast delivery product for operational meteorology use, this product was also generated as an output from the third reprocessing as it is useful for QC. This product contains the averaged Brightness Temperature and Sea Surface Temperature at 10 arc minute resolution.
Further details on the Level 2 AR and Meteo products are available in the AATSR Handbook.
