  abstract = {{T}he relative skill of 21 regional and global biogeochemical models was assessed in terms of how well the models reproduced observed net primary productivity ({NPP}) and environmental variables such as nitrate concentration ({NO}3), mixed layer depth ({MLD}), euphotic layer depth ({Z}(eu)), and sea ice concentration, by comparing results against a newly updated, quality-controlled in situ {NPP} database for the {A}rctic {O}cean (1959-2011). {T}he models broadly captured the spatial features of integrated {NPP} (i{NPP}) on a pan-{A}rctic scale. {M}ost models underestimated i{NPP} by varying degrees in spite of overestimating surface {NO}3, {MLD}, and {Z}(eu) throughout the regions. {A}mong the models, i{NPP} exhibited little difference over sea ice condition (ice-free versus ice-influenced) and bottom depth (shelf versus deep ocean). {T}he models performed relatively well for the most recent decade and toward the end of {A}rctic summer. {I}n the {B}arents and {G}reenland {S}eas, regional model skill of surface {NO}3 was best associated with how well {MLD} was reproduced. {R}egionally, i{NPP} was relatively well simulated in the {B}eaufort {S}ea and the central {A}rctic {B}asin, where in situ {NPP} is low and nutrients are mostly depleted. {M}odels performed less well at simulating i{NPP} in the {G}reenland and {C}hukchi {S}eas, despite the higher model skill in {MLD} and sea ice concentration, respectively. i{NPP} model skill was constrained by different factors in different {A}rctic {O}cean regions. {O}ur study suggests that better parameterization of biological and ecological microbial rates (phytoplankton growth and zooplankton grazing) are needed for improved {A}rctic {O}cean biogeochemical modeling.},
