PRELIMINARY STUDY ON REMOTE SENSING THE RELATIONSHIP BETWEEN THE BRIGHT-

ETER AND THE LIGHTNING ACTION INTEGRAL

T
he integral of lightning current squared over time, named as the“lightning action integral”, is an indicator of
Joule heat generated by lightning discharge. The temperature of air molecules is thus increased, which can
be observed by a ground-based microwave radiometer for atmospheric temperature remote sensing. Obser-
vational experiments were performed in early summer in 2017 with a ground-based, MWP967KV type micro-
wave radiometer, which is commonly used for atmospheric temperature profile remote sensing but has been
properly-configured this study in order to observe the artificially triggered lightning events at Guangzhou
field experiment site for lightning research and test (GFESL). Data from the radiometer and the instrument for
recording lightning current have been analyzed and the results from seven effective events show that a rela-
tionship like TB=exp (aX) may exist between the brightness temperature increment, TB, in unit of K, observed
in 30-50GHz band and the lightning action integral, X, in unit of A2s, calculated from high temporal resolution
lightning current records. The correlation coefficient is as high as 0.8863 while the coefficient, a is equal to
6.25381*10-5 (sample size =7).
