| Summary: | Abstract. Today, the routine assimilation of satellite data into operational models of ocean circulation is mature enough to enable the production of global reanalyses de-scribing the ocean circulation variability during the past decades. The expansion of the “reanalysis ” concept from ocean physics to biogeochemistry is a timely challenge that motivates the present study. The objective of this pa-per is to investigate the potential benefits of assimilating satellite-estimated chlorophyll data into a basin-scale three-dimensional coupled physical–biogeochemical model of the North Atlantic. The aim is on the one hand to improve fore-casts of ocean biogeochemical properties and on the other hand to define a methodology for producing data-driven cli-matologies based on coupled physical–biogeochemical mod-eling. A simplified variant of the Kalman filter is used to |
