Re: Low reflectances after l2gen processing of VIIRS SDR from CSPP

Many thanks, Sean! I agree 'compatible' wasn't the right word. What I meant was that, in the past (I'm talking about ~7 years ago, CSPP VIIRS SDR v2.0), it was enough to set the gains to 1 to get reasonable numbers out of l2gen from such an CSPP-derived input. In retrospective, it was very naive of ...

Low reflectances after l2gen processing of VIIRS SDR from CSPP

Hi there, We are trying to set up a NRT processing chain for Suomi-VIIRS data we acquire at level 0. We are using CSPP to process it from level 0 to level1, then l2gen for processing the resulting VIIRS SDR up to level 2. The l1->l2 step is done as follows: input_file="SVM01_npp_d20210618_t1149...
