Data sets

ERA-40 reanalysis ECMWF https://apps.ecmwf.int/datasets/data/era40-daily/levtype=sfc/

Short summary

Decadal variability in Caspian Sea water properties (temperature, salinity, density) is investigated using a numerical modeling approach. The paper illustrates the sea response to global climate change, including abrupt surface-level variations and the strengthening of water stratification. Water exchange between the three Caspian basins (northern, middle and southern) is demonstrated to play an important role in the formation of the sea 3-D circulation.
