Analysis of the Seasonal Dependence of the Brightness Temperature of the Glacier Sheet of Antarctica by Microwave Satellite Data

Resumo

In this paper, an analysis of seasonal dependences of the brightness temperature of different regions of Antarctica according to radiometer data from MIRAS (SMOS satellite) and SSMIS (DMSP series satellites) is presented. Queen Maud Land (Norwegian: Dronning Maud Land) was chosen as the region of study, 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 as a function of the change in climatic characteristics of regions is considered. The main factors influencing the change in brightness temperature in different regions of the Antarctic glacier sheet are revealed.
