  1. Input product file: Select the input product file by either typing the product path into the text filed or by pressing the file selection button to invoke a standard file dialog.
  2. Output product file: Select the output product file by either typing the product path into the text filed or by pressing the file selection button to invoke a standard file dialog.
  3. Output product format: Select one of the available output product formats. Currently BEAM-DIMAP, HDF5 and GEOTIFF format are available.
  4. Generate cloud mask only:If selected, only the cloud mask will be generated
  5. Perform BAER and generate aerosol products: If selected, BAER algorithm ill be applied and aerosol (AOT & alpha) bands will be written
  6. Generate atmospherically corrected reflectances: If selected, atmospheric correction will be performed and corrected reflectance bands will be written
  7. Atmospheric correction algorithm: Select the method to estimate the surface reflectance between UBAC and SMAC.
  8. Aerosol phase lookup table: Select the look-up table for the coefficients of the aerosol phase function to be used.
  9. Bitmask: Specify a boolean expression which selects the pixels to be processed by the BAER processor

The BAER Processing Request File

The following table describes the BAER specific processing request file parameter. For a detailed description of the processing request file concept and file specification please look at the general description section.

Parameter name Description Type Example Value
type Request type. Mandatory attribute of the Request element String "BAER"
bitmask Bitmask expression which evaluates to a Boolean value. Pixel is used for processing only if the bitmask evaluates to true. String "l2_flags.LAND"
aer_phase_lut Lookup table for aerosol phase function coefficients. Can be "LACE-98", "OPAC_AC" or "OPAC_CC" String "LACE-98"
atm_corr_method Method used for atmospheric correction. Can be "SMAC" or "UBAC". String "UBAC"
cloud_process Whether or not only a cloud mask shall be derived. Boolean "true"
baer_process Whether or not the BAER algorithm shall be applied. If true, aerosol parameters are generated. Boolean "true"
atm_cor_process Whether or not atmospheric correction shall be applied. If true, corrected reflectances are generated. Boolean "true"
