Spring Updates from the Fire Modeling and Analysis Committee
Lisa Saperstein, USFWS - Landfire and the Interagency Fuel Treatment Decision Support System Updates for Alaska.
A new set of Landfire maps are planned for release in May 2021 using new imagery. IFTDSS has a series of module updates including exposure analysis, quantitative wildfire risk and assessment, and fuel treatment effectiveness monitoring.
Eric Miller, BLM-AFS - Evaluating the Drought Code Using in Situ Drying Timelags of Feathermoss Duff in Interior Alaska
Drying timelag is a concept that derives from the logarithmic drying rate equation that is useful in classifying components of a fuel bed based on speed of moisture loss. It is used in the Canadian Forest Fire Weather Index System to calculate current moisture content from a previous value based on weather and environmental conditions. An understanding of how timelag varies according to the physical and hydrological properties of boreal soils allows a better interpretation of the DC in Alaska as well as the causes of its eccentricities.
