Minimize Level-2 SRAL/MWR Product Types

A Level-2 SRAL/MWR complete product contains three files in netCDF format:

  • one "reduced" (Red) data file, containing a subset of the main 1 Hz Ku band parameters
  • one "standard" (Std) data file containing the standard 1 Hz and 20 Hz Ku and C-band parameters
  • one "enhanced" (Enh) data file containing the standard 1 Hz and 20 Hz Ku and C-band parameters, the waveforms and the associated parameters necessary to reprocess the data (at least in LRM mode).

Each of these three files contains one or more data sets from among the following:

  • "20-Hz LRM/SAR_Ku" data set: set of 20 Hz Ku-band parameters issued from SRAL tracking measurements performed in LRM and SAR modes
  • "20-Hz LRM/SAR_C" data set: set of 20 Hz C-band parameters issued from SRAL tracking measurements performed in LRM and SAR modes
  • "1-Hz LRM/SAR_Ku/C" data set: set of 1 Hz Ku/C-band parameters issued from SRAL tracking measurements performed in LRM and SAR modes.
