Greg has been working with the Climate Hazards Group since its inception, starting as a graduate student and now as Assistant Researcher and Principal Investigator. Greg received his MA from UCSB looking at global landcover maps under Dr. Jack Estes. This Masters research led him to the FEWS NET work, and satellite estimates of rainfall. His PhD work focused on developing statistical tools for leveraging existing products to provide improved rainfall monitoring and forecasting. Notably was the development of the Standardized Precipitation Index (SPI) using satellite RFE combined with disparate historical records, and the development of the Forecast Interpretation Tool (FIT) to combine probabilistic forecasts with historical records. Recent work has returned him to his land remote sensing training by estimating cropped area using limited satellite imagery acquisitions and statistical expansion over wide areas. Current work focuses on cropped area estimation, developing rainfall monitoring tools to better capture crop conditions and the synthesis of a variety of indicators to estimate crop production conditions for a finite area.
