分裂窗演算法

① 地表溫度的溫度數據

NASA官網的搜索就可以找到。有圖例說明，也有數據說明，不過都是英文版的,但也可以轉換成中文。

② 陸地表面溫度反演的方法是什麼

利用分裂窗演算法反演陸地表面溫度的研究進展

PROGRESS IN SPLIT-WINDOW ALGORITHMS FOR RETRIEVING LAND SURFACE TEMPERATURE

俞宏 石漢青

摘 要：本文對LST反演的分裂窗演算法作了回顧和比較.LST反演的分裂窗演算法最一般的形式是TS=T4+A(T4-T5)+B,其中TS是陸地表面溫度,T4和T5分別是AVHRR分裂窗通道4和5的亮溫度,A和B是由大氣、觀測角及地表輻射率所決定的系數,不同的演算法其系數的確定有很大的不同.地表比輻射率的確定是LST反演中的主要難點,目前也有多種方法來確定地表比輻射率值.最後本文還指出了目前在LST反演中存在的局限性.
