Hydrographic: This is the first version (1.0) of a hydrographic climatology for the region 47 to 65 °N, 15 °W to 15 °E. It contains monthly and yearly mean temperature and salinity data at 179 depth levels on a 0.25° x 0.5° latitude-longitude grid in the period 1890 to 2011. For the calculation of the means all available temperature and salinity data from water sample, CTD, and float measurements in this period were selected from the World Ocean Database 2009, the ICES (International Council for the Exploration of the Sea) data base, and the BSH data base, rejecting double stations. The derived data base consisted of about 735,000 stations. The original profiles of temperature and salinity were interpolated on 179 depth levels. There was no interpolation if the gap between two measurements in the original profile was too large. The data were then sorted in 0.25° x 0.5° latitude-longitude boxes. Atmospheric: This is the first version (1.0) of a meteorological climatology for the region 47 to 65 °N, 15 °W to 15 °E. It contains monthly mean air temperature, air pressure, dew point, relative humidity and windspeed data on a 1° x 1° latitude-longitude grid in the period 1950 to 2010. For the calculation of the means all available data from voluntary ship observations and buoys measurements in this period provided quality controlled by the DWD (Deutscher Wetterdienst) were taken.
