Twenty years of monthly global maps of Hue angle, Forel-Ule and Secchi disk depth, based on ESA-OC-CCI data

Data consist of global monthly-averaged maps of Hue angle, Forel-Ule index and Secchi disk depth at ~ 4 km spatial resolution at the equator. Data extend from 1997 and 2018 and were generated from the ESA-OC-CCI v4.0 multi-sensor merged remote-sensing reflectances. Two downsized subproducts are also provided: - The global dataset, reduced at 1 degree spatial resolution - A North Atlantic dataset, reduced at 0.25 degree spatial resolution
