NOAA MSL12 multi-sensor DINEOF global gap-filled products: Chlorophyll-a, diffuse attenuation coefficient Kd(490), and suspended particulate matter (SPM)

B2022167_A1_WW00_chlora_120.png The NOAA Multi-Sensor Level-1 to Level-2 (MSL12) Ocean Color, science quality, multi-sensor global gap-filled analysis includes chlorophyll-a, Kd(490), and SPM products. These global gap-free data are generated using the data interpolating empirical orthogonal function (DINEOF) method (Liu and Wang, 2022). The data that go into this product currently come from 3 instruments: the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor aboard the Suomi National Polar-orbiting Partnership (SNPP) satellite, VIIRS on the NOAA-20 satellite, plus the Ocean and Land Colour Instrument (OLCI) on the Sentinel 3A satellite from the Copernicus program of the European Union.

NOAA MSL12 Ocean Color, science quality, VIIRS multi-sensor (SNPP + NOAA-20), chlorophyll DINEOF gap-filled analysis

V2020006_A1_WW00_chlora_120.png 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.
