Analysis of thermal infrared emissivity for sand dust source regions in northwest China


Abstract:
Various types of surface emissivities for dust source regions in northwest China were measured by 102F.The comparison between field measured spectra and the ASTER JHU spectral library data showed the reliability and necessity of the field measurement.The analysis results showed that emissivity had significant differences for different types of land surface.The regular differences in emissivity for the same type surface were related to the different physical characteristics.The emissivity was relatively stable on the time scale.The measurement and analysis of the emissivity data for the sand dust source regions provide important information for sandstorm related researches.
