Computation of the Particulate Organic Carbon (POC) v5 products on sinusoidal and geographic projections at 4 km resolution are based on a modified remote sensing reflectance (Rrs) band ratio algorithm by Stamski et al. (2008): 292*Rrs(490)/Rrs(560)^-1.49. The Rrs at 490 and 560 nm were obtained from the European Space Agency (ESA) Ocean Colour Climate Change Initiative version 5 dataset (OC-CCI v5) (Sathyendranath et al., 2021). The coefficient parameters of the algorithm were estimated by applying Type II linear regression model to a global in-situ and OC-CCI v5 satellite match-up POC products. Uncertainties of log_10 transformed POC in each pixel were computed by weighting the uncertainties in each OC-CCI optical water class by their membership (Brewin et al., 2017; Jackson et al., 2017).
