Retrieval of Plant and Soil Temperature by AMTIS Data
Now the remote sensing of LST is an important task of us. Components temperature retrieval is the main object of LST retrieval. If the emissitivity or temperature of components is obviously different
the information of components’ temperature can be extracted from the multi angle radiance data. In this paper
we construct the matrix model of infrared radiance
analyze the correlation of W K×J
choose the optimal viewing angles and select the parameters that can be retrieved. Then based on data of the airborne sensor AMTIS developed in China
through geometrical and atmospherical correction
the plant and soil temperature in mixed pixels are separated using matrix retrieval method. The results and the error analysis show that the accuracy of retrieved soil temperature is good
but the result of retrieved plant temperature is not good enough.
