“…Taking into consideration the lognormal distribution of chlorophyll data (Campbell, 1995), all error estimates and corrections were made to the log-transformed (base 10) data. The root mean square error (RMS) and bias were calculated at each pixel according to Gregg and Casey (2004) and Marrari et al (2006):…”

“…The global improvement in model-observation bias produced by application of a single scaling factor of ∼6, would translate to a significant global-scale bias in satellite chlorophyll-a concentrations or MLD climatology values. Based on past evaluations of these products (de Boyer et al, 2004;Marrari et al, 2006), a systematic bias of such magnitude seems unlikely. The assumption that isoprene is well-mixed through the MLD is an approximation.…”

“…The straight lines represent several different bio-optical models (4,37,38). methods, however, will yield different results depending on the composition of pigments within the phytoplankton, and errors can be on the order of 50% (24)(25)(26). The presence of significant amounts of chlorophyll b, characteristic of chlorophytes, prochlorophytes, and cryptophytes, causes fluorometric techniques to underestimate Chl.…”
