Geospatial Environmental Modeling of Climatic Hazards and Their Impacts (climateGEM)


Overview

Understanding climate requires the study of important geospatial and environmental components. For example, climatic hazards such as drought do not occur uniformly across a region, and the spatial patterns of such threats can and do change seasonally and interannually. Additional factors such as changes in elevation across an area make the resulting impacts vary even more. Through Geospatial Environmental Modeling (GEM) we assess and anticipate environmental impacts from climatic hazards at regional scales as they have played, are playing, and might play out over time.

Led by Jeremy Weiss, this new research focus of the laboratory integrates traditional analysis techniques from the atmospheric and related sciences with geospatial data modeling to investigate climatic hazards and their impacts. In addition to aggregating climate data in a state-of-the-art geographic information system (GIS), this new research focus will serve as the hub for web map visualization tools that enable the public to view geospatial data from new and potentially powerful research perspectives.
