LEE: NSSL Balloon-Borne Electric Field Meter (EFM) Data


Balloon-borne Electric Field Meters (EFMs) were launched into lake effect snow bands during LEE to measure the electric field associated with these storms. The balloon-borne EFM provides in-situ measurements of a storm’s vertical and horizontal electric field. The combination of the spin (powered by the instrument) and rotation (caused by lift through the storm) provides the modulation that enables measurement of the electric field. 8 different EFMs, flown multiple times, were developed and maintained by the National Oceanic and Atmospheric Administration / Office of Atmospheric Research / National Severe Storms Laboratory, OU / CIWRO, and TTU staff. Data set includes binary data files for each launch during the field project.
