Airborne Doppler Wind Lidars: Overview and recent research projects
G. D. Emmitt, PhD
President and Senior Scientist
Simpson Weather Associates, Inc.
Airborne Doppler Wind Lidars have been used for atmospheric research since the 1970’s. The speaker has been involved with their use since 1981 when NASA/MSFC flew a C02 coherent Doppler lidar on a Convair 990 to map multiple thunderstorm outflow interactions as part of CCOPE. Since that time, we have used coherent Doppler lidars on the NASA DC8 (MACAWS and now DAWN), a Navy’s Twin Otter (TODWL) and a Navy’s P3 (P3DWL). Within the last 5 years the TODWL has been used in marine boundary layer experiments, mountain meteorology experiments, C-17 Wing Tip Vortices studies, and several model validation campaigns. Current projects include an ADWL on NOAA’s P3 for the 2014 hurricane season and NASA’s DC8 for two Arctic missions.
Dr. Emmitt has more than 40 years of experience performing atmospheric research using tethered balloons, radars, lidars and mesonets. Since the early 1980’s he has focused much of his effort upon the use of Airborne Doppler Wind Lidars (ADWL) to probe the lower atmospheres associated with typhoons, tornadoes, marine boundary layers, low level jets and other organized flows within the atmospheric boundary layer. Over that past 10 years, an increasing emphasis has been on numerical model (WRF, COAMPS and EPA CALMET) validation. He works with the Army, Navy, and Air Force, as well as NASA and NOAA, on the use of lidars and the interpretation of the data recorded. He has experience installing, operating three ADWLs and analyzing the data from customized coherent detection lidars based upon the Wind Tracer product developed by CTI and LMCT.
