Satellite Based Aridity Mapping
نویسندگان
چکیده
For the instantaneous dryness mapping, the satellite derived aridity index is proposed. The proposed index is derived from the day/night surface temperature and the maximum solar flux, also it is proved that the index corresponds to the thermal admittance from the theoretical analysis of the surface energy balance. From the MODIS LST and reflectance product during 10 years, daily/monthly global aridity map are made and compared with the NDVI and solar zenith.
