Abstract:By comparing monthly maximum Land Surface Temperature (LST) of January 1999 retrieved from NOAA-AVHRR data with the result from ground observation, it is found that there is a correlation coefficient of 0.86 with a standard deviation of 5.6℃ between the monthly maximum LSTs from remote sensing and those from ground observation. Monthly maximum LSTs retrieved from remote sensing are generally 2.8℃ lower than those from ground observation. It is necessary to revise LSTs retrieved from remote sensing to reduce the mean deviation between them and LSTs from ground observation without any delay. After the revision of the monthly maximum LSTs retrieved from remote sensing, the correlation coefficient between the modified monthly maximum LSTs retrieved from remote sensing and LSTs from ground observation remains 0.86, the standard deviation is reduced from 5.6℃ to 5.2℃, and the mean deviation decreases from 4.9℃ to 4.1℃. Although the modified monthly maximum LSTs retrieved from remote sensing remain lower than those from ground observation, the mean deviation is reduced from 2.8℃ to 0.1℃.
