| Abstract: | Using enhanced vegetation index(EVI) and land surface temperature(LST) dataset derived from TERRA/MODIS synthetic products MOD13 A2(16-day composite,DOY 209 in 2010) and MOD11 A2(8-day composite,DOY 209 and 217 in 2010),the LST-EVI two-dimensional characteristic space was constructed,and then TVDI(temperature-vegetation drought index) was extracted to indicate the top-soil moisture of northern Ti-bet.Furthermore,the simulated soil moisture was verified by synchronously measured data in the field.The two gro... |
