![]() ![]() High-speed lightning photography and spectroscopy.In particular, NASA satellites map lightning on planet Earth, 24 hours per day, following our discovery of the strong emissions from the first multiplet of oxygen (OI) atoms at 777.4 nm. Lightning Spectroscopy We have discovered and mapped the emissions from lightning in the 400-900 nm wavelength range.The effects of lightning on the environment are a key focus of our research. The Houston Lightning Mapping Array (LMA) is a recent addition to our research projects and detects all lightning emissions, both CG and IC emissions, within 200 km of Houston. NLDN and the LMA My research focuses on a wide range of topics using the National Lightning Detection Network (NLDN) with a database of CG lightning from June 1983 to the present. ![]() He has over 150 reviewed publications identified in ResearcherID. This instrumentation base consists of the WSR-88D installations in Texas, access to the National Lightning Detection Network (NLDN), which Orville established in the 1980’s, and a recent installation of a total Lightning Mapping Array (LMA) around Houston. Nielsen-Gammon, Schumacher and Zhang) has developed a comprehensive program on the meteorological characteristics of lightning associated with lightning discharges to ground. Orville, in cooperation with other faculty, (Drs. ![]()
