These instruments will allow researchers to analyze storms from both below and above, and closely examine thunderstorms' impact on Earth's atmosphere.įollow Samantha Mathewson Follow us Facebook and Google+. A Nikon D6 camera with a 50 mm lens was used, in a video mode of 60 frames per second. Researchers will soon have the opportunity to capture even better storm observations from space using NASA's Lightning Imaging Sensor, which was installed on the orbiting lab in February 2017, and the Atmosphere-Space Interactions Monitor, which is slated to launch to the space station later this year. The mission objective was to manually record lightning and transient luminous events from the Cupola window in the ISS, based on preliminary thunderstorm forecasts uploaded to the crew 24-36 hours in advance. "We've gotten better at finding them, but it's mostly case-based analysis." The light is generated by the excitation of nitrogen molecules due to electron collisions (the electrons possibly having been energized by the electromagnetic pulse caused by a discharge from an underlying thunderstorm). "TLE studies have been, to an extent, fortunate observation," Tim Lang, an atmospheric scientist at NASA's Marshall Space Flight Center, said in the statement. They occur in the ionosphere 100 km above the ground over thunderstorms. Transient Luminous Events in the lower part of the Atmosphere originated in the Peripheral Regions of a Thunderstorm A.Chilingarian, G.Hovsepyan, T.Karapetyan, B.Sargsyan, E. Transient luminous events (TLEs) are short-lived electrical discharge that occur in the upper atmosphere. Furthermore, researchers also aim to learn more about why storms produce different TLEs in different circumstances. Observations of strange atmospheric features like red sprites and blue jets help improve researchers' understanding of lightning and thunderstorms, which can lead to better storm models and weather forecasts. Transient Luminous Events Red spritesare large but weak luminous flashes that appear directly above an active thunderstorm system and are coincident with powerful positive cloud-to-ground lightning strokes. These red sprites, which were spotted in August 2015, stretched roughly 60 miles (100 km) above Earth, according to the statement. Recently, however, astronauts aboard the space station have been able to capture various natural light shows on camera, including red sprites over two different storms within 3 minutes of each other - first over the American Midwest and then later near the coast of El Salvador. Some of the first observations of these events were of red sprites photographed by cameras on board the space shuttle, as well as from images taken during a NASA and University of Alaska airborne campaign. In fact, visual evidence of TLEs wasn't available until 1989.
