Performances of AMSR2 (Advanced Microwave Scanning Radiometer 2) installed on Japanese GCOM-W1 (Global Change Observation Mission 1st–Water) satellite launched on 18 May 2012 are considered. Problems of brightness temperature Тb(ν) modeling at AMSR2 frequencies ν, development of advanced algorithms for oceanic and atmospheric parameter retrieval and Тb(ν) calibration in space are discussed. Algorithms for retrieval of total water vapor content, total cloud liquid water content and wind speed developed on the base of the modeled Тb(ν) are considered. Examples of AMSR2 data processing acquired over marine weather systems are given.
