The ESI tracking system monitors drought by picking up signals of plant stress. This narrated visualization demonstrates how drought developed in 2010, 2011, and 2012.For complete transcript, click here.This video is also available on our YouTube channel. The Evaporative Stress Index (ESI) provides objective, high-resolution information about the evaporation of water from land surface. The ESI model combines satellite data with other meteorological factors to determine how much water is used by crops and vegetation. The resulting data helps to detect drought.This visualization shows ESI data for 2010, 2011, and 2012. 2010 was a relatively wet year despite occasional drought. In 2011, the ESI shows extremely dry conditions across all of Texas, Louisiana, and Oklahoma, tracking one of the country s corn and soy been supply.The kind of early-warning detection system ESI provides will enhance the US arsenal of drought monitoring tools and help farmers adapt to drought before it evolves.

Still image showing Evaporative Stress Index data from August 18, 2012, when the drought in the mideast US was extremely high and spread over several states. Evaporative Stress Index color scale.
