Paper Abstract

Every year there are ice disasters in the Bohai Sea, which bring serious effect on the human’s life and production. So how to monitor the ice disaster becomes an important issue. The remote sensing technology has a good advantage of monitoring ice disaster over others. In this paper, NOAA/AVHRR data is used to retrieval each parameter of sea surface. Firstly, according to the worked brightness temperature difference can separate sea from land. Then taking advantage of the difference of the albedo of visible light and near infrared band to get rid of clouds and seawater, however, due to the thin ice albedo there exists some errors, thus we can use the multi channel split window method (MCSST) further extraction of sea ice in accordance with sea surface temperature, then we can get the sea ice area on the basis of number of pixels and satellite spatial resolution. Secondly, after getting the region of sea ice, sea ice thickness can be obtained through the empirical formula between ice thickness and near infrared band albedo. Lastly, after solving the extraction of the ice information within mixed pixels, ice concentration also can be calculated.
