CSL is partnering with San Jose State University for a 6 week aircraft-based study of wildfire behavior and its response to spatially and temporally evolving wind fields in California. A NOAA Twin Otter will be outfitted with a scanning Doppler lidar to measure horizontal wind fields, plume vertical dynamics, spatial extent and transport. The aircraft will also have a high-resolution infrared imaging system to track the behavior of the active flame front and other sensors to measure fire radiative power (FRP). Ground-based mobile scanning radars and lidars will be positioned around the fire to track the temporally evolving input wind field and the spatial structure and internal dynamics of the fire plume while the NOAA Twin Otter flies overhead to track fire behavior and strength and make dynamics measurements over a larger spatial scale. Airborne CSL instruments include NightFox (for FRP) and a ARS Micro-pulse Doppler lidar (MicroDop) sidescanner for lidar. For ground-based measurements, CSL will have a stationary scanning Doppler lidar (staDOT) and a mobile Dppler lidar (PUMAS).
