Özet

Statistical sea surface temperature (SST) and chlorophyll a (Chl.a) maps and fields (monthly, seasonal and annual) have been prepared for the Black Sea region in the framework of the SeaDataNet project. Daily MODIS/Aqua (SST and Chl.a) and SeaWiFS (Chl.a) level 2 (L2) datasets were utilised to produce 1 km resolution final products, which are disseminated through the Internet. Data processing was done with the SeaDAS (SeaWiFS Data Analysis System) software package. Standard algorithms were used for calculation of Chl. a and SST. Only 'clean' pixels (i.e. pixels without any SeaDAS flag) were taken for averaging. Data interpolating empirical orthogonal functions (DINEOF) method was tested to reconstruct missing SST data, however, it did not work properly in conditions of insufficient data, producing some unrealistic results so it was not applied to the final products. In total, about 500 averaged maps and fields were prepared for period of September 1997 to December 2004 (Chl. a from SeaWiFS) and for period July, 2002, December 2007 (Chl. a and SST from MODIS).
