GOCI chlor_a algorithm description

by emaure » Mon Jun 15, 2020 10:00 pm America/New_York

Hi All,

I recently download GOCI images and in the metadata for chlor_a the Hu, C., Lee Z., and Franz, B.A. (2012). Chlorophyll-a algorithms for oligotrophic oceans: A novel approach based on three-band reflectance difference, J. Geophys. Res., 117, C01011, doi:10.1029/2011JC007395 reference is given but I cannot find the description of the GOCI algorithm for chlor_a in this https://oceancolor.gsfc.nasa.gov/atbd/chlor_a/#sec_2.
So, I was wondering, where I can get such information?

Thanks
Eligio

For GOCI we use an OC3 variant (similar to MODIS) with the following coefficients:

chloc3_wave=[443,489,555]
chloc3_coef=[0.2515,-2.3798,1.5823,-0.6372,-0.5692]
