VIIRS-SNPP degradation since Dec 2017

by pgarnesson » Mon Feb 25, 2019 5:51 am America/New_York

Dear OceanColor team,
it seems the degradation of VIIRSN has increased during 2018 for most of the wavelenght.
Is there something planed to improve (as done with MODIS with continuous calibration)?
I have also noted a recent switch to 9.3.0-V2019.0 processing: are these changes reported/detailed somewhere?
The plots attached show some intercomparisons using MODIS as the reference and the effect on the GSM CHL algorithm.

Indeed, it is in need of an update :wink:
We're working on a revised calibration that will be applied with an upcoming reprocessing.  We will likely implement a similar forward stream refined processing strategy for VIIRS-SNPP that we do for the MODIS instruments after the reprocessing.
