How to use

  • ・Physical quantity=DN*slope + offset
  • ・Valid values are during Minimum_valid_DN~Maximum_valid_DN
  • ・Bit-14 (non-polarization) and 15 (polarization) of QA_flag are set when the grid is recovered by the pre-day’s BRDF table. Available data on the target day can be identified by selecting the pixel of the Bit-14 (15 for the polarization channels)=0.
