【摘要】 应用四种典型的劈窗算法 ,对南宁市区范围 1 998～ 2 0 0 1年 3 6景 NOAA-AVHRR图像数据进行陆面温度的试算对比 ,并用四个气象观测站点的地面观测数据预测图像相应时刻的地温来与各种算法反演地温相对比 .在此过程中 ,对图像数据进行了大气散射校正 ,并使用大气散射校正数估算大气水分含量 .最后 ,采用一种劈窗算法制作了南宁市城区陆面温度等值线图 ,得到比较理想的结果更多还原

【Abstract】 Four split window algorithms were compared to retrieving land surface temperature on four meteorological stations using NOAA-AVHRR images of 36 scenes in 1998~2001 years,and the land surface temperature was compared with forecasting land surface temperatures using observer data. Atmosphere scatter correcting was applied to image data, and the value of atmosphere scatter correction was used to account water vapor content. A split window algorithm was used to make contour map of the land surface temperature on NANNING City, the result is ideal.更多还原
