NOAA MSL12 Ocean Color - Science Quality - VIIRS SNPP

Updated: July 17, 2020

VIIRS Science Quality Ocean Color Level 2 (EDR) is produced by NOAA/STAR Ocean Color Team through NOAA Multi-Sensor Level 1 to Level 2 processing system (MSL12) using an improved calibration for the satellite data record (OC-SDR, which is Level 1b). CoastWatch Level-3 composites, binned and mapped data products also available.

Updated: October 26, 2020

VIIRS Ocean Color multi-sensor gap-filled analysis (Level 4) is produced with input from the VIIRS multi-sensor (SNPP + NOAA-20) daily merged chlorophyll and monthly climatology using the DINEOF method of interpolation for gap-filling. The chlorophyll algoritm used is OCI. The NOAA ocean color science team provides the gap-filled data file to NOAA CoastWatch. CoastWatch converts these to the NetCDF product and serves them.
