Research Abstract

Following two researches were carried out in order to develop the technique which estimates the physical parameters of the snowpack on the earth surface from satellite observation data acquired in the close future.
1. The multifrequency microwave radiometer is passive sensor, which observes the multiple microwaves in which the combination of frequency and polarization differs, and it is also the one on AMSR mounted at the ADEOS-Il that the launch has been scheduled in 2000. From the data observed at five selected frequencies of AMSR, the algorithm for extracting two different snowpack parameters was developed. Using snowpack parameters observed in the Hokkaido district generally, the effectiveness of developed algorithm was investigated. The result of the investigation showed being effective so that the algorithm may measure depth and grain size of the snowpack of wide area.
2. The technique that estimated the snowpack parameter using the phase information, which is included for multiple microwave images obtained by the observation of synthetic-aperture radar, was developed. Simulation and analysis of the data to be obtained when the L band interferometric SAP (InSAR) observed the snowpack with the layered structure were carried out. The result of the analysis showed that the scattering effect from the boundary in the snow layer was smaller than scattering effect from the ground, and that it is effective so that InSAR using the frequency of the L band may measure the depth of the snowpack at the good accuracy. In addition, that to visualize the spatial distribution of the depth of the snowpack using the interference fringe was possible also clarified.
