Retrieval of a High-Precision Drought Monitoring Index by Using GNSS-Derived ZTD and Temperature

Potential evapotranspiration (PET) is a key parameter for calculating drought monitoring index that is generally difficult to obtain. In addition, PET has low spatial resolution and can only be obtained at a site-based point. Therefore, retrieving PET with high precision, high spatial resolution, an...
