This project addressed SNPLMA Round 10 Subtheme 3c - Understanding basin meteorology, and the issue of developing and/or improving meteorological data and monitoring tools for use in forecasting and making burn day decisions for prescribed fires. The products and deliverables from this project for the Lake Tahoe Basin included: 1) a 300-m gridded climatology of surface wind; 2) a 4-km mixing height climatology with associated transport wind; 3) 400-m resolution gridded operational forecasts of surface wind; 4) new weather station observations during the project period for an elevation transect within the Tahoe Basin; and 5) a customized smoke prediction website tool. These deliverables were developed from a suite of existing tools including the operational CANSAC forecast system at the Desert Research Institute, the Bluesky smoke prediction framework, WindNinja and field weather instruments. The project was developed in response to identified needs of improved meteorological information for burn day decisions after consultation with Lake Tahoe Basin Management Unit, California Air Resources Board, and USFS Predictive Services personnel.
