In regional scale, satellite data was gained frequency nearly a day or more shorter, and these satellite data had already been wildly used for drought monitoring. Meanwhile, a variety of information systems of drought monitoring based on client/server architecture were developed and employed. However, these systems were too professional for non-professional workers to use. With the development of...
Vegetation Health Index is computed based on the vegetation index and land surface temperature which are very important satellite products for drought monitoring with remote sensing. The quality of Temperature Condition Index and Vegetation Health Index deeply depends on the quality of the Land Surface Temperature (LST). The present retrieval algorithm of Moderate Resolution Imaging Spectroradiometer...
One of the most serious droughts in last century occurred in Sichuan Basin in the summer of 2006. In this paper, three different methods were used to monitor this drought. The first method is TVDI (Temperature Vegetation Dryness Index). The second method is TMVDI (Temperature Microwave Vegetation Dryness Index). NDVI in method one was replaced by MVI. Because the microwave radiometer data can be obtained...
