Minimize Level-2 Processing Overview

The SLSTR Level-2 processing is performed via three processors:

In addition to the core processing modules (L2_sst, L2_l2p, L2_lst, L2_frp, L2_aod):

  • the module L2_in checks the input L1B data and auxiliary files. Their presence and self-consistency are verified;
  • the module L2_com gathers general functions as derived pixel-by-pixel estimates of radiance, BT, radiance uncertainty and BT uncertainty for channel S2, S3, S6 to S9, F1 and F2;
  • the module L2_out populates and writes the product metadata and data fields.
