Minimize AATSR Products Availability

Level 0

Once AATSR instrument source data were received on the ground, they were converted to a Level 0 product. Since AATSR had only one nominal operating mode, there was only one type of L0 product, comprising header information and a main dataset containing the source packet information. Full information on the L0 products is available in the AATSR Handbook.
Note that AATSR L0 products are not routinely available to users.

Level 1

The Level 1B Product consists of TOA brightness temperatures and reflectance values at full resolution for both the nadir and forward views (7 channels each view, 14 measurements total) of the conical scan. The Level 1B product is the base product for all Level 2 processing. The product is produced systematically in stripline form, from which portions may be extracted using multiples of the 512 km by 512 km minimum scene size.

Level 2

The following Level 2 products are available for AATSR (Envisat format):

  • Full resolution geophysical product (ATS_NR__2P)
  • Spatially averaged geophysical product (ATS_AR__2P)
  • Subset of the spatially averaged geophysical product (ATS_MET_2P)
  • Sea Surface Temperature (UPA-L2P/UPA-L3U)
  • Land Surface Temperature (ATS_LST_2P).

Level 3

The following Level 3 products are available for AATSR (NetCDF format):

  • UOL AATSR Level 3 LST Products (ENVISAT.ATS.LST_3P)
