The Evaporative Stress Index (ESI) is a thermal indicator of anomalous ET conditions that can be used for drought monitoring. CALMIT has been involved in several ESI projects to develop and test ESI-related products for drought detection and assessment within the U.S. and North American Drought Monitors. The work involves the development of ESI products at multiple spatial scales using thermal observations the GOES and MODIS sensors and testing their applicability for drought monitoring in the U.S. and globally. Research also includes the downscaling of ESI to landscape scales for field to sub-field assessments using Landsat imagery.
