Professor Matthew Clark has received new funding from CAL FIRE that will seek to assess where high severity wildfires will occur in California using satellite and other spatial data, such as winds. A core component of this research is data from the NASA Global Ecosystem Dynamics Investigation (GEDI) sensor on the International Space Station, which uses a scanning laser to measure the height profile of vegetation. This data will help predict vegetation fuels that can influence wildfire behavior. This research will involve undergraduate students in paid internships through the Center for Interdisciplinary Geospatial Analysis (CIGA) to help collect ground data from plots in forests around California. This data will help calibrate and validate models.
