  abstract = {{T}he third primary production algorithm round robin ({PPARR}3) compares output from 24 models that estimate depth- integrated primary production from satellite measurements of ocean color, as well as seven general circulation models({GCM}s) coupled with ecosystem or biogeochemical models. {H}ere we compare the global primary production fields corresponding to eight months of 1998 and 1999 as estimated from common input fields of photosynthetically-available radiation ({PAR}), sea-surface temperature ({SST}), mixed-layer depth, and chlorophyll concentration. {W}e also quantify the sensitivity of the ocean-color-based models to perturbations in their input variables. {T}he pair-wise correlation between ocean-color models was used to cluster them into groups or related output, which reflect the regions and environmental conditions under which they respond differently. {T}he groups do not follow model complexity with regards to wavelength or depth dependence, though they are related to the manner in which temperature is used to parameterize photosynthesis. {G}lobal average {PP} varies by a factor of two between models. {T}he models diverged the most for the {S}outhern {O}cean, {SST} under 10 °{C}, and chlorophyll concentration exceeding 1 mg {C}hl m 3 . {B}ased on the conditions under which the model results diverge most, we conclude that current ocean-color-based models are challenged by high-nutrient low-chlorophyll conditions, and extreme temperatures or chlorophyll concentrations. {T}he {GCM}-based models predict comparable primary production to those based on ocean color: they estimate higher values in the {S}outhern {O}cean, at low {SST}, and in the equatorial band, while they estimate lower values in eutrophic regions (probably because the area of high chlorophyll concentrations is smaller in the {GCM}s). {F}urther progress in primary production modeling requires improved understanding of the effect of temperature on photosynthesis and better parameterization of the maximum photosynthetic rate.},
