Abstract:

In this project, the potential of using passive microwave PMW emissivity instead of the direct use of Tb information in the detection and analysis of FT states will be investigated. The advantage of using emissivity instead of Tb is that emissivity values are expected to provide invaluable information about the state of the surface since the dielectric constant of the surface changes significantly during the FT process. However, the direct use of Tb is typically fraught with atmospheric and temperature noises. Transition between freeze and thaw states depends on the amount of heat energy the surface receives or releases and on the corresponding change in seasonal and diurnal temperature. This project aims to develop a method using emissivity estimates from two similar kind of passive microwave sensors AMSR-E and AMSR2 for FT states detection.
