Quantitative Calculation of Sea Ice over the Bohai Sea Using NOAA/ AVHRR Imagery

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.
