Minimize Common Processing Parameters
Three kinds of auxiliary files are used in the preliminary sections of SLSTR Level-2 processing, common to all processing branches:
  • The SLSTR Level-2 S6 Nadir Shortwave Infra-red Noise data file contains a Look-Up Table (LUT) which maps measurements of detector noise over the SLSTR internal calibration black bodies to estimates of noise for individual S6 nadir measurement pixels.
  • The SLSTR Level-2 Thermal Infra-red (TIR) Noise data file contains LUTs which map measurements of detector noise over the SLSTR internal calibration black bodies to estimates of noise for individual measurement pixels. There are two netCDF files for each of the S7, S8 and S9 channels; one each for the nadir and oblique views and one netCDF file for channels F1 nadir view.
  • The SLSTR S7 and F1 Thermal Infra-red (TIR) Characterisation data files are Level-2 ADFs containing LUTs for conversion of brightness temperature into radiance for the S7 and F1 nadir channels.
