Long-term moisture analysis using Remotely sensed data in Mongolia
The purpose of this research work is to estimate long-term soil moisture moisture content in central part of Mongolia. The soil moisture (SM) content is one of the most important environmental variables in relation to land surface climatology, hydrology and ecology. Climate is changing in the global...
