Discrimination of sea ice edge in the Antarctic, from NOAA MSU
スポンサーリンク
概要
- 論文の詳細を見る
Discrimination of the sea ice edge is done using the microwave 50.3 GHz brightness temperature measured by NOAA satellites. Considering the emissivity variation between the open sea and sea ice, the contour of 232K brightness temperature is regarded as the ice edge. The method is very simple but contains several sources of uncertainty owing to the atmospheric effect and low resolution. Limits and possibilities of the method are discussed. Horizontal distributions of sea ice are compared to the AVHRR imagery and good agreement is found. An annual variation of sea ice distribution is presented.
