| Research Abstract |
The sea ice rapidly decreasing in the northern hemisphere. For the future, especially thin sea ice area is expected to melt. Then, the purpose is to estimate the sea ice thickness using passive microwave sensor. The analysis did the observation and the calculation of the radiative process of sea ice. As a result, 18GHz horizontal is effective, and the snow on sea ice is important to estimate the thickness. The models of the sea ice were improved and compared observational data. As a result, the microwave emission of the sea ice with different thickness became possible to estimate of high accuracy.
