CSDMS all hands meeting 2013

Use of satellite remote sensing to study land surface changes during extreme events

Venkat Lakshmi, University of South Carolina Columbia South Carolina, United States.

[[Image:|300px|right|link=File:]]Satellite remote sensing is a powerful tool for terrestrial hydrological studies. In particular studies of droughts and floods - hydrological extremes can be well accomplished using remote sensing. In particular, we will use data from the visible-infrared and microwave sensors on NASA platforms to studies the onset and propagation of droughts as well as spatial extent of flooding. In this talk we will present numerous examples of hydrological extreme events and the use of satellite remote sensing as a tool for mapping the spatial extent and the temporal persistence. The droughts of 1988 and 2012 in the United States Midwest, flooding in 1993 and 1998 are strong examples in United States. There have been numerous such events in Asia in India, Pakistan and China which have affected billions of people who depend on the land and agricultural productivity to a much greater degree than in United States.
