- Evapotranspiration and evaporative demand
- Drought monitoring and early warning
- Secular and climate-scale hydrologic trends
- Land surface-atmosphere interactions
- Drivers of hydrologic spatio-temporal variability
My goal is to advance drought and famine early warning by improved estimation and innovative exploitation of atmospheric evaporative demand. This entails fundamental research into land surface/atmosphere hydrology and outreach to stakeholders in the drought-monitoring and scientific communities. I generate reference evapotranspiration reanalyss for NOAA's stakeholders across the continental US and for FEWS NET's science comunities in food-insecure countries, and I convert these reanalyses into a drought index--the Evaporative Demand Drought Index (EDDI)--that offers early warning and ongoing monitoring of agricultural and hydrologic drought.
