Associate Research Scientist, Climatology
David has been with the Desert Research Institute (DRI) and Western Regional Climate Center (WRCC) since 2003 as an Associate Research Scientist in Climatology. His professional interests cover a broad spectrum within the fields of climatology, meteorology, and physical geography including expertise in drought, mountain weather/climate, spatial analysis of climate data, GIS, field research, and climate/drought monitoring. He has been a national author for the U.S. Drought Monitor since 2012 and works in collaboration with the NOAA National Integrated Drought Information System (NIDIS) Regional Drought Early Warning Systems (DEWS) on drought issues for the western U.S. As part of the WRCC’s operations, David currently authors the NOAA Pacific Region (Hawaiian Islands, U.S. Affiliated Pacific Islands) Quarterly Climate Impacts & Outlook Report and rotates authoring the WRCC Monthly Climate Summary for the western U.S. Other current project activities include collaboration with the National Park Service (NPS) Inventory and Monitoring Program (I&M) overseeing operations and management of weather/climate monitoring networks for the Pacific Island and Mojave Desert I&M networks.
During the past 17 years at DRI, David has worked on a wide variety of projects in the fields of meteorology and climatology with state, federal, and university entities including: Bureau of Land Management, California Department of Water Resources, California Energy Commission, Coordinating Research Council, Fallon Naval Air Station, National Center for Atmospheric Research, National Renewable Energy Laboratory, National Science Foundation, National Weather Service, NOAA National Centers for Environmental Information, NPS I&M Program, Northern Arizona University, Scripps Institution of Oceanography, Southwestern Research Station (American Museum of Natural History), State of Wyoming, Storm Peak Laboratory, University of California White Mountain Research Center, University of California Natural Reserve System, University of Nevada-Reno, U.S. Environmental Protection Agency, U.S. Forest Service, and U.S Geological Survey. From 2009-2011, Mr. Simeral was lead site surveyor (Western U.S.) for the NOAA U.S. Regional Climate Reference Network.
