Table 3. Chl Algorithm Performance From MODIS/Aqua Measurements for Chl <= 0.25 mg m-3, as Gauged by in Situ Chla
Algorithm RMS URMS Mean Ratio Median Ratio MRE R2 (Linear) R2 (Log) N
OC3 77.7% 44.2% 1.24 1.05 32.0% 0.42 0.66 63
CI 43.9% 32.7% 1.15 1.04 25.4% 0.62 0.71 63
aMODIS/Aqua Rrs(lambda) were used as the input of all algorithms. URMS, "unbiased" RMS (see text for details); MRE, mean relative error after converting negative errors to positive.
