Level-2 product definition
Level-2 product definition#
The Level-2b SSS product is obtained through application of the SSS retrieval algorithm, given the Level-1b TBs. The product is provided in the L-band grid of the CIMR instrument (\(xdim_{grid},ydim_{grid}\)). There is also one SSS retrieval per CIMR look direction (aft and fore views). The product is provided in netCDF format and contains the variables listed in Table 1.
