基于MODIS数据反演云南省地表温度，采用分裂窗算法需要参数较少、易实现。研究表明：云南省地表温度由北向南递增，东部高、西部低，基本符合云南省实际情况。利用气象观测站实测数据进行验证，平均误差为3.16℃，两组数据基本接近，证明基于MODIS数据和分裂窗算法反演云南省地表温度是可行的。
基于MODIS數據反縯雲南省地錶溫度，採用分裂窗算法需要參數較少、易實現。研究錶明：雲南省地錶溫度由北嚮南遞增，東部高、西部低，基本符閤雲南省實際情況。利用氣象觀測站實測數據進行驗證，平均誤差為3.16℃，兩組數據基本接近，證明基于MODIS數據和分裂窗算法反縯雲南省地錶溫度是可行的。

Land Surface Temperature (LST)of Yunnan Province was retrieved using the split window algorithm based on MODIS data.This algorithm needs fewer parameters and is easy to achieve.The results showed that the temperature was increased spatially from north to south in Yunnan.The eastern land surface temperature is higher than the west.The result was accorded to the actual situation of Yunnan.The observed data of the weather was used to verify the retrieval result.The average error was 3.16℃.Two groups of data were very close.Therefore,it was practicable to retrieve land surface temperature in Yunnan province applying the split window algorithm based on MODIS data.
