Minimize Level 1 Algorithms and Products

The SLSTR Level-1 algorithm is divided into three processing modes.

  • Calibration mode, producing the VISCAL file used to calibrate the SLSTR product produced during the next orbit.
  • Observation mode, producing the entire SLSTR product, including top of atmosphere Brightness Temperature (BT) and radiances.
  • Joint observation/calibration mode, encompassing the two previous modes (not explained in this documentation).

The Level-1 product is therefore divided into two kinds of product.

  • Calibration Level-1 product, including only the VISCAL Auxiliary Data File (ADF) with its associated metadata file.
  • Observation Level-1 product, including measurement data files (including BT, radiances and several annotation files).
