Analysis of the Seasonal Dependence of the Brightness Temperature of the Ice Sheet of Antarctica by Microwave Satellite Data
The paper presents an analysis of seasonal brightness temperature variations of different regions of Antarctica according to the data of MIRAS (SMOS satellite) and SSMIS (DMSP series satellites) radiometers. As a region of study, the Dronning Maud Land was chosen which includes the main zones of Antarctica: the dome, the zone of runoff winds and the coastal zone. The interrelation of time dynamics of brightness temperature from the change of climatic characteristics of regions is considered. The main factors influencing the change of brightness temperature in different regions of the Antarctic ice sheet are revealed.
