The SeaDataCloud Temperature and Salinity Climatologies have been processed from the SeaDataCloud historical Data Collection of the North Atlantic Ocean including temperature and salinity in situ data of the water column in the North Atlantic Ocean (from 10°N to 65°N including the Labrador Sea) for period 1950 – 2019. Several versions are proposed in seasonal and monthly format for seven decadal periods (1950-1959/1960-1969/1970-1979/1980-1989/1990-1999/2000-2009/2010-2019). A subset of the CORA dataset has been integrated as external data-source to improve the product’ spatial and temporal coverage.
