Due to the important role of phytoplankton in the carbon cycle in the ocean, it is necessary to understand the relationships between concentration and distribution of photosynthetic pigments and physical and biological features that are easily obtained. In this work, we use the BRASIL-SR radioactive transfer model to estimate incident solar radiation over the sea surface with the aid of GOES-8 data. The estimations are weighed against the available cloud cover and sea surface temperature data (SST/AVHRR), and correspond to monthly means for 1998 and 1999. The area to be studied encompasses the whole Brazilian coastline (34,5o to 55o W and 6o to 34o S). The main goal is to analyze the temporal and spatial variability on the solar radiation, cloud cover and SST data in order to identify oceanic regions along the Brazilian coast that present potential characteristics for phytoplankton ocurrences.
