Dust aerosol can cause the change of the land surface temperature(LST) by altering the thermal infrared radiative transfer of earth-atmosphere system.The influence of different winter and summer dust aerosol optical depth(AOD) on thermal infrared brightness temperature(BT) and LST retrieval was systematically studied and the inversion results influenced by water vapor in the atmosphere and surface factor were also studied.Thermal infrared radiative transfer calculation indicates that 1.brightness temperatur...
