Abstract: Monthly Enhanced Vegetation Condition Index (EVCI) and Temperature Condition Index (TCI) data in Hunan were retrieved from MODIS, and the correlation analysis was conducted by comparing with the meteorological drought composite index (CI) from 97 meteorological stations in Hunan. Remote- sensing drought monitoring model based on drought composite index (CI) was established by selecting appropriate weights and different remote-sensing drought levels were classified. The authors applied the remote-sensing drought monitoring model to drought monitoring from June to September of 2013 in Hunan, the model could reflect the spatio-temporal evolution of the drought well. This model weakens the effects of cloud to a certain extent and could be applied to crop growth monitoring, crop production estimation and natural disaster loss assessment in the humid south.
