Observed Kinematic Structure of Fire Plume Using Ground-Based Remote Sensing Instrumentation
Hall E (New Orleans Convention Center )
Allison Charland, San Jose State Univ., San Jose, CA; and C. B. Clements

Doppler wind lidar and sodar observations of a fire plume were obtained during an experimental prescribed burn conducted in complex terrain located near San Jose, CA. A ground-based Halo Photonics, Ltd. Stream Line 75 Lidar acquired Doppler wind velocities and backscatter intensity in and around the fire plume from multiple vertically pointing and RHI scans. Additionally, fire-induced winds were observed at the fire front using horizontal scanning strategies. An Atmospheric Systems Corporation (ASC) miniSoDAR placed downwind of the burn area obtained vertical velocities and turbulence structure within the fire plume. These observations allowed for the study of the kinematic structure and spatial and temporal evolution of the fire plume.
