T-28 Formation Flights with the Special-Purpose Test Vehicle for Atmospheric Research (SPTVAR) for Calibration of Electric Field Vector Retrievals (NMEX 1997)
Overview
The armored T-28 deployed to Albuquerque, New Mexico, to carry out electric
field measurement intercomparisons with the SPTVAR aircraft operated by
the New Mexico School of Mining and Technology (NMIMT). Flights were carried
out in the vicinity of small thunderstorms that formed near NMIMT's Langmuir
Laboratory, west of Socorro. The aircraft flew in close formation around
the bases of these storms, as well as through some of the precipitation
shafts. The SPTVAR was equipped with two quasi-independent systems of electric
field meters. The flights thus yielded 3 sets of measurements, two
from SPTVAR and one from the T-28, from which estimates of the ambient
vector electric field and aircraft charge were derived. Comparisons among
the 3 systems were generally good, and allowed some exploration of the
effects of corona emission on the measurements.
