The primary scientific goals of DC3 involved improving our understanding of the chemical impacts of thunderstorms and their anvils. However, the Colorado domain provided opportunities to study other interesting phenomena, including the potential impacts of smoke ingestion on convection and thunderstorms, electrification processes in smoke plumes and pyrocumulonimbus clouds, and the production of sprites by unconventional thunderstorm.
We report the observations of two gigantic jets, one during daytime over sea and one at nighttime over land, in the context of detailed associated observations of lightning flash and discharge evolution provided by a variety of radio measurements.
