| Abstract: |
| With the development of remote sensing application,many kinds of surface temperature retrieval algorithms have been proposed.This paper analyzed the relevant algorithms,explained the relevant parameters of mono-window algorithm and their calculation methods in detail.Finally,true land surface temperature in the urban area of Chengdu was obtained based on the mono-window algorithm by using Landsat ETM data.The research has shown the following.In the case of lacking detailed cross-section data of the atmosphere,it is feasible and reliable to study the urban thermal island effect by using the mono-window algorithm. |
