Abstract

TASI can provide abundant useful information for the retrieval of emissivity spectrum and temperature. This paper sums up the progress of land surface temperature; summarize several methods for temperature and emissivity separation analyse the advantage and disadvantage of each method. In addition, This paper establishes regression between MMD and min using 274 laboratory reflectance and field emissivity spectra, analyzes its accuracy using the data field measuring, and evaluates urban surface diurnal temperature range. Due to the effects of scale and atmosphere, the predicted value does not equal to the laboratory measurement, but the pattern of predicts is similar to the laboratory measurement; Therefore, the accuracy of this method can satisfy operational application and it is feasible to retrieve the emissivity spectrum and temperature for TASI data. Based on this relation, the TASI thermal infrared data were used for inversion and retrieval of the SiO2 content in the Xuemisitan area. The result of inversion conforms to the geological fact.
