This webinar is co-hosted by LANDFIRE and members of the Joint Fire Science Program: Great Basin Fire Science Exchange, Southwest Fire Science Consortium, and the Northern Rockies Fire Science Network. Content will address challenges that managers of large landscapes deal with in these regions. The LANDFIRE Program strives to produce consistent fire behavior fuel model grids for the U.S. These models are relevant for predicting fire behavior, including spread and intensity, during average conditions; however, they often fall short during drought or seasonably dry conditions. To address the need for that information, LANDFIRE developed a seasonal product named the Modeling Dynamic-Fuels with an Index System (MoD-FIS). These provisional products have been released for the Southwest and Great Basin regions, and are ready for testing and review by those who use LANDFIRE data. In this webinar, Charley Martin, LANDFIRE Fuels Team Lead, and Tobin Smail, Fire and Fuels GIS specialist, both Technical Support Services Contractors to the USGS Earth Resources Observation and Science (EROS) Center, offer a MoD-FIS primer, explain how the products can be used in these regions, and solicit users’ input and review.
