Dr. Crimmins is trained as an applied climatologist and meteorologist and has ten years experience in the application of climatological methods, tools, and data for natural resource management. Watershed management was his focus for several years while working as a private sector environmental scientist. In that position, he provided expertise on hydroclimatology, urban and agricultural non-point source runoff modeling, remote sensing and GIS applications for watershed management.
Dr. Crimmins is currently on the faculty of the Department of Soil, Water, and Environmental Science at the University of Arizona and is a Climate Science Extension Specialist for Arizona Cooperative Extension. In this position he provides climate science support to resource managers across Arizona by assessing information needs, synthesizing and transferring relevant research results and conducting applied research projects. His extension and research work supports resource management across multiple sectors including rangelands, forests/wildfire, and water resources as well as policy and decision makers. This work aims to support managers by increasing climate science literacy as well as developing strategies to adapt to a changing climate. He also serves as a drought monitoring expert on the Arizona Governor’s Drought Task Force and has worked with counties across Arizona to implement drought preparedness and impact monitoring plans.
