Multichannel microwave radiometer MTVZA-GY onboard of meteorological satellite Meteor-M N 1 performs carries out measurements of outgoing radiation of the atmosphere-underlying system. Both internal and external calibrations of the measured radiation as well as the results of numerical integration of microwave radiative transfer equation are used to derive brightness temperatures T Bs at vertical (V) and horizontal (H) polarizations at MTVZA-GY frequencies. Radiosonde data for T Bs modeling and comparison with the measured values were selected for various physical-geographical regions. The spatial structures of the marine weather systems measured by MTVZA-GY and AMSR-E were mainly similar. Their differences were due to the differences in the incidence angle: 55° for AMSR-E and 65° for MTVZA-GY. © 2010 IEEE.

The brightness temperatures TBs measured by Aqua AMSR-E and Meteor-M N 1 MTVZA-GY microwave radiometers as well as the total atmospheric water vapor content, total cloud liquid water content and sea surface wind speed retrieved from the TBs are used to study the structure and evolution of severe marine weather systems and to improve temporal resolution required for their satellite monitoring. The microwave data are compared with visible and infrared images and with in situ observations. The microwave signatures of tropical and polar hurricanes are compared to get more accurate data on the emissivity of the surface at gale winds. © 2012 IEEE.

14th Specialist Meeting on Microwave Radiometry and Remote Sensing of the Environment, MicroRad 2016 - Proceedings | Year: 2016

On July 8, 2014 meteorological satellite Meteor-M No. 2 with a module of temperature and humidity atmospheric sensing MTVZA-GY was launched on a circular sun-synchronous orbit. Microwave radiometer MTVZA-GY has 16 scanner channels at frequencies of 10.65, 18.7, 23.8, 31.5, 36.5, 42.0, 48.0 and 91.65 GHz and 13 sounder channels at frequencies in the ranges of 52-57 and 176-191 GHz and carries out conical scanning of the Earth at angle of incidence 65°. Swath width is 1500 km. The brightness temperatures TBs were computed by numerical integration of microwave radiative transfer equation using the radiosonde and reanalysis atmospheric profiles as the input information. The TBs for the Amazon forest and the Ocean under clear sky and weak winds were selected for the vicarious calibration. The long-term stability of MTVZA-GY operation was examined by analysis of time series of TBs measured over the Eastern Antarctica (Dome C), Greenland (GEOSummit) and Amazon rain forest test areas. TBs time series were also obtained for the GCOM-W1 AMSR2 measurements. MTVZA-GY data were used for study of severe marine weather systems. © 2016 IEEE.
