Absolute spectral irradiance measurements of lightning from 375 to 880 nm.

Abstract

A spectrometer-detector optical multichannel analyzer system capable of absolute spectral irradiance measurements has been used to record the time-integrated emissions (150 or 300 ms) from cloud-to-ground lightning. Two detectors, one operating in the 375-695 nm region and one in the 650-880 nm region, recorded emissions from the same lightning. A summary table of spectral irradiance values in 50 nm increments is presented. -from Authors
