摘要：Land surface temperature is one of the most important factors in climatology studies and human – environment interactions. Besides, land surface temperature is also an important factor when monitoring soil moisture. Ground-based observations reflect only thermal condition of local area around the station and in fact cannot establish the number of meteorological stations with expected density due to the high cost. Remote sensing technology with advantages such as wide area coverage and short revisit interval has been used effectively in the study of land surface temperature distribution. This article provides a synthetic analysis method of the actual problems monitoring the land surface temperature using LANDSAT thermal infrared image for monitor drought.
