IMOS - SRS - MODIS - 01 day - Chlorophyll-a concentration (Carder model)

The Aqua satellite platform carries a MODIS sensor that observes sunlight reflected from within the ocean surface layer at multiple wavelengths. These multi-spectral measurements are used to infer the concentration of chlorophyll-a (Chl-a), most typically due to phytoplankton, present in the water.

There are multiple retrieval algorithms for estimating Chl-a. These data use the Carder method implemented in the SeaDAS processing software l2gen and described in Carder K. L., Chen F. R., Lee Z. P., Hawes S. K. and Cannizzaro J. P.
