Quantitative Calculation of Sea Ice over the Bohai Sea Using NOAA/ AVHRR Imagery
-
摘要: 利用NOAA及FY-1卫星监测渤海海冰的亮度温度、反照率及其与海水的差异建立了冰、水识别判据,并根据海冰反照率与冰厚的关系,对海冰进行分类。在解决了混合象元内含冰信息提取的基础上,计算了海冰覆盖度和面积等参数。Abstract: According to the difference of brightness temperature and albedo between sea ice and sea water over the Bohai Sea monitored by NOAA and FY-1, the criterion of distinguishing water from ice is set up, and according to the relationship between albedo and thickness of sea ice, the sea ice is classified. Based on the ice information within mixed pixel, the coverage and area of sea ice are computed.
