Data quality processing information | Several data sets were used to develop and validate the model. The largest one is still available at http://www.science.oregonstate.edu/ocean.productivity/field.data.c14.readme.php. Since field data were insufficient to calibrate the model in several regions, PP estimates from other models (VGPM, HYR, and the MOD-27 formulation (Esaias, 1996)) were considered as measurements where there were none. Therefore, this model can be regarded as a metamodel.
As vertical profiles with very high (and possibly biased) P/B ratios were filtered out, the PP estimates obtained from this model tend to be slightly lower than those from several other models. Comparisons with other global models of phytoplankton primary production can be found in Carr et al. (2006), Friedrichs et al. (2009), Saba et al. (2010a, 2010b) and Lee et al. (2015).
