DISPATCH is a disaggregation algorithm of the low-resolution soil moisture (SM) estimates derived from passive microwave observations. It provides disaggregated SM data at typically 1 km resolution by using evaporative efficiency (SEE) estimated optical/thermal collected around solar noon. based on relationship between evapo-transpiration rate and surface under non-energy-limited conditions hen...

Droughts are normal recurring climatic phenomena that vary in space, time, and intensity. The spatial and temporal variability and multiple impacts of droughts provide challenges for mapping and monitoring on regional scales. With the launch of new generation sensors such as Moderate Resolution Imaging Spectroradiometer (MODIS), the monitoring of aberrant climatic events may be explored in an e...

Passive microwave surface soil moisture (SSM) products tend to have very low resolution, which massively limits their application and validation in regional or local-scale areas. Many climate hydrological studies are urgently needed evaluate the suitability of satellite SSM products, especially alpine mountain areas where plays a key role terrestrial atmospheric exchanges. Aiming overcome this ...

Taking the Dadu River Basin in Danba area of Ganzi Prefecture, Sichuan Province as research area, based on 2013 and 2016 Landsat8 remote sensing images, temperature vegetation drought index (TVDI) method is used to divide dry valley into 6 arid gradient regions. Using ArcGIS10.5 software Fragstats4.2 calculate landscape pattern different areas years, combined with survey results agricultural po...
