The SDC_BAL_CLIM_TS_V1 product contains Temperature and Salinity Climatologies for the Baltic Sea including seasonal and monthly fields for the 1955-2014 period and seasonal and monthly fields for 6 decades starting from 1955 and ending in 2014. The climatological fields were computed from merged Baltic Sea data that combines data extracted from the 2 major sources: 1) SeaDataNet infrastructure and 2) Coriolis Ocean Dataset for Reanalysis. The computation was done with the DIVAnd (Data-Interpolating Variational Analysis in n dimensions), version 2.3.1.
