Atmospheric Integrated Water Parameters in the Arctic: Seasonal Variability and Influence on the Amsr2 Measured Microwave Radiation of the Sea Ice-Atmosphere System

In this study Era-Interim re-analysis data on the atmospheric total water vapor content (WVC), total cloud liquid water content (CWC), ice water content (IWC) and profiles of the atmospheric meteorological parameters for the whole 2015 year are used to analyze WVC, IWC and CWC seasonal variability over the sea ice and sea water surfaces and estimate the influence of the atmospheric integrated water parameters on the total microwave radiation of the sea ice and sea water - atmosphere system at the frequencies and polarizations of the Advanced Microwave Scanning Radiometer 2 (AMSR2). The brightness temperature (BT) of the sea ice - atmosphere system microwave radiation for the AMSR2 channel characteristics is modeled for the conditions of non-scattering atmosphere. The arrays of BTs are calculated using published data on the sea ice emissivities and Era-Interim re-analysis data on the sea ice concentration (SIC) and temperature.
