GLOBAL BIOGEOCHEMICAL CYCLING ESTIMATES WITH CZCS SATELLITE DATA AND GENERAL-CIRCULATION MODELS

Computed geophysical fields from a 3-D general circulation model are c oupled with the Coastal Zone Color Scanner (CZCS) satellite data on ch lorophyll content of surface ocean waters. The CZCS satellite data on chlorophyll content of surface ocean waters are used to estimate the ' photochemical lability' of dissolved organic matter in the surface oce an. Monthly estimates are made of the global ocean to atmosphere flux of a biogeochemically important gas, carbonyl sulfide (OCS), with 2.8- degrees x 2.8-degrees latitude-longitude spatial resolution. This nove l technique provides a conceptual and computational method for integra ting data collected as part of future satellite measurement campaigns, such as the Earth Observing System (EOS) and Sea-viewing Wide-field-o f view Sensor (SeaWiFS), with 3-D chemistry-climate prediction models.
