Evaporative Demand Drought Index (EDDI): Tracking the “atmospheric demand” side of drought for monitoring and early warning

Imtiaz Rangwala, Mike Hobbins, and Jeff Lukas for the EDDI Team*

EDDI is a drought indicator that examines changes in the atmospheric evaporative demand to indicate the spatial extent and severity of drought over multiple timescales. In this webinar, we will describe the physical basis of EDDI and summarize some early results that demonstrate its potential and added value in early warning and ongoing monitoring of drought. We will also describe the various resources available from the EDDI tool, and share insights gained from our engagement with a diverse set of stakeholders on its effectiveness and usability.
