A Global Climatology of Phytoplankton Pigment Concentration
Abstract
Satellite ocean color imagery and in-situ measurements are combined to generate a monthly climatology of phytoplankton pigment concentration over the global oceans at 0.09 degree resolution. The climatology includes data from CZCS (Nov 78 - Jun 86), POLDER and OCTS (Nov 96 - Jun 97), SeaWiFS (Sep 97 - Aug 01), and the SeaBASS archive (Mar 61 - Aug 01). The satellite data sets are individually calibrated against in situ measurements. The various time-series data, satellite and in situ, are weight-averaged to produce climatological values for each month of the year. An average, monthly varying ice mask is used. A temporal interpolation followed by a spatial interpolation based on classic triangulation of available nearest neighbors is performed to fill up missing information. The resulting climatology is compared with previous climatologies and analyzed for seasonal variability on regional to global scales.
