GOES-East and GOES-West radiance products on EUMETCast soon

The CSR and ASR Level-2 products, in BUFR format, contain radiance data as well as metadata for use in operational data assimilation applications. The 2 km infrared pixels are subset into 15x15 pixel processing boxes and combined with ABI L2 cloud products to allow assessment of the quality of the L1b data to calculate an optimal radiance value as well as useful quality control metrics.

The CSR product is a subset of the ASR product and is further reduced in data volume by only reporting values in clear sky conditions. The ASR product expands on the fields present in the CSR product to include information about all pixels in the processing box as well as the subset of cloudy pixels.
