Remote Sensing: Drought Monitoring and Early Warning

In recent decades, various kinds of remote sensing-based drought indexes have been proposed and widely used in the field of drought monitoring. In the past few decades, satellite-based remote sensing has provided relatively high spatial resolution and high temporal resolution. Remotely sensed imagery provides spatial continuous spectral measures across large areas that reflect both atmospheric and land surface characteristics. It aims to give a retrospective insight into the spatio-temporal evolution of agriculturally relevant droughts in consideration of growing seasons and agricultural areas.
