Lightning strikes are bright and loud鈥攙iolent enough to shake your bones and light up the sky. Now, a new study led by the University of Colorado Boulder suggests that these powerful events may also alter the chemistry of Earth鈥檚 atmosphere, even affecting Earth鈥檚 all-important ozone layer.</p> <p>The results, <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2021JD034914" rel="nofollow">published in the <em>Journal of Geophysical Research: Atmospheres</em></a>, shed new light on what it means to live on a planet rife with lightning.&nbsp;</p> <p>鈥淵ou have about 1,800 active thunderstorms across the globe at any given time, generating about 50 flashes per second,鈥 said Robert Marshall, a coauthor of the new study and assistant professor in the <a href="/aerospace/" rel="nofollow">Ann and H.J. Smead Department of Aerospace Engineering Sciences</a>.</p> <p>All that flashing may have a broader impact on the atmosphere than scientists once thought, he said.&nbsp;</p> <p>The research hinges on a complicated phenomenon called lightning-induced electron precipitation, or LEP. Whenever lightning strikes, Marshall explained, the bolt shoots off a pulse of electromagnetic energy that can spread all the way around the Earth and into space. There, that energy interacts with the radiation belts that surround our planet, rattling loose some of the electrons trapped inside鈥攚hich then rain back down toward Earth.</p> <p>Picture it like shaking a tree branch to knock off wet snow.&nbsp;</p> <p>In their new study, he and colleagues tracked the fallout from three thunderstorms over the last decade that stretched from Nebraska to the Caribbean. Based on their calculations, these individual storms may have kicked off a chemical chain reaction in the atmosphere that caused the ozone layer to shrink in certain locations by as much as 5%鈥攁 loss that potentially lasted for up to 12 hours.</p> <p>Humans have lived with lightning for a long time, so those fluctuations in ozone likely don鈥檛 threaten peoples鈥 safety. But, Marshall said, the team鈥檚 findings hint that鈥攚hen spread over dozens of storms all happening at once鈥攍ightning could have a surprisingly big influence on what happens in the air above our heads. The researchers are hoping to study just how sizable that global influence is next.</p> <p>鈥淎 single lightning strike has a minor impact on the atmosphere,鈥 Marshall said. 鈥淏ut over thousands of lightning strikes, it may be much more significant. We don鈥檛 know yet.鈥</p> <h2>Lightning crashes</h2> <p>It can also be something to behold. In October 2015, for example, Hurricane Patricia made landfall in Texas and Mexico. The storm brought some rain and flooding to the region鈥攏ot to mention more than 33,000 lightning strikes over the span of just two-and-a-half hours.&nbsp;</p> <p>In their latest research, Marshall and his colleagues used detailed computer simulations to follow what happened in the atmosphere after that wild event鈥攑lus a similar storm in the Caribbean in May 2017 and one more than roiled the skies above Nebraska in August 2013.&nbsp;</p> <p>鈥淭hese storms are triggering electrons to be removed from the radiation belts,鈥 Marshall said. 鈥淚t dumps energy into the atmosphere, and we鈥檙e asking what is that energy input doing to the atmosphere?鈥</p> <p>Here鈥檚 what happened: As the storms progressed, the electron energy raining down to Earth began to react with gases high in Earth鈥檚 atmosphere, roughly 30 to 70 miles above the surface. Concentrations of certain molecules in the air, including hydrogen oxides and nitrogen oxides, shot up almost at once. Nitrogen oxides, for example, increased by as much as 150%.&nbsp;</p> <p>On their own, these gases can鈥檛 do much harm. But, Marshall said, they may mix deeper into the atmosphere, eventually reaching the ozone layer鈥攁n important boundary that sits less than 20 miles above the ground and helps to shield life from the sun鈥檚 radiation.</p> <p>鈥淭he increase in nitrogen oxides can last for 24 hour or more, and those gases will slowly descend in altitude where they can destroy ozone,鈥 Marshall said.&nbsp;</p> <p>The team doesn鈥檛 expect that destruction to spread far away from the area just above the storm, creating a short-lived thin patch in the ozone layer. But the loss in ozone is comparable to what scientists have observed during other major atmospheric disturbances, including the aurorae, or Northern Lights, that make the sky glow at high latitudes.&nbsp;</p> <p>Going forward, Marshall and his colleagues intend to keep an eye on those dark and stormy nights.&nbsp;</p> <p>鈥淚n this study, we鈥檙e looking at the effect of individual storms,鈥 he said. 鈥淭he next step is to say what鈥檚 the global, cumulative effect of lighting on the upper atmosphere.鈥</p> <p><em>Wei Xu, a former postdoctoral scholar at 兔子先生传媒文化作品, was the lead author of the paper.

They can be used to demonstrate new satellite technologies, to test new capabilities, or to provide hands-on educational experience to students. In recent years, however, CubeSat technology has matured to the point that full-fledged operational or science missions can be conducted from these small satellites. This development has opened the door to unique, focused science missions with big impact that can be designed, built, and operated by universities such as 兔子先生传媒文化作品.</p> <p>My research group is currently developing three CubeSat science missions: AEPEX, CANVAS, and COSMO. I will give an overview of these three missions and how they fit into the overall research program of the LAIR research group. I will then use the CANVAS mission to illustrate how the development of CubeSats contributes to science, engineering, and education in our department. CANVAS is designed to measure and map very-low-frequency (VLF) radio waves in low-Earth orbit; these radio waves play a key role in controlling the fluxes of energetic electrons in the Earth鈥檚 radiation belts. Results from this mission will provide the first quantitative assessment of global VLF energy injected into space from below. Like our other CubeSats, CANVAS also has its share of unique engineering challenges, resulting in the development of several novel solutions. Finally, as an NSF-funded mission, CANVAS is driven by both research and education, and is therefore developed largely by students in the Graduate Projects curriculum in the Aerospace Engineering Sciences department. These students take on technical and leadership roles that provide training and experience for their future careers. This brief overview of the CANVAS CubeSat will show how science, engineering, and education come together in pursuit of this unique mission.</p> <p><strong>Bio: </strong>Bob Marshall is an Assistant Professor in the Aerospace Engineering Sciences department at the University of Colorado Boulder, where he leads the Lightning, Atmosphere, Ionosphere and Radiation Belts (LAIR) research group. His broad range of research interests include lightning and its effects in space; meteors; and coupling between the radiation belts and the upper atmosphere.

We want to better understand that coupling.鈥</p> <p>These particles can be damaging to spacecraft electronics and the health of astronauts.</p> <p>The process that leads them to enter Earth鈥檚 atmosphere has long been recognized, but past studies have generally monitored single locations. Whether from a ground station looking up or a satellite staring down, they can only see what is directly in their path.</p> <p>Marshall wants to build a three-dimensional map of the particles across thousands of square kilometers.</p> <p>鈥淵ou can measure the particles with a satellite, but it鈥檚 a single point measurement. It doesn鈥檛 tell you what鈥檚 happening elsewhere, or give an idea of the spatial extent of the coupling region. You could do it with multiple satellites to cover a larger area, but that gets very expensive,鈥 Marshall said.</p> <p>Marshall has found an answer in very low frequency (VLF) radio waves, used by the Navy to communicate with ships and submerged submarines. Most radio waves have limited range, but VLF signals interact with and bounce off the Earth鈥檚 ionosphere, allowing the signals to be received thousands of kilometers away.</p> <div class="image-caption image-caption-left"> <p> </p><p>Bob Marshall</p> </div> <p>鈥淚f you observe these signals, they vary dramatically with time. This variation is caused by shifts in the lower part of the ionosphere along the path between the transmitter and the receiver. When we observe these signal variations, they can tell us how the lower ionosphere is changing,鈥 Marshall said.</p> <p>The ionospheric coupling is most prevalent at northern latitudes, so Marshall is focusing his efforts on the ionosphere above Canada.</p> <p>He intends to set up an autonomous network of ten or more receivers at locations across northern Canada. The data collected will be fed into a computer model to build a continuous 3D map of the ionosphere.</p> <p>The research also opens up educational opportunities for high school students.</p> <p>鈥淎 challenge with this project will be finding sites and getting to these sites to install the receivers. The number of populated places in Canada falls quickly as you go further north. Our approach is to find a small-town high school and work with a science teacher,鈥 Marshall said. 鈥淲e get students involved so they can learn about space science and instrumentation that they would never normally be exposed to. It鈥檚 critical to the research, but also part of the broader impacts of the project.鈥</p> <p>The VLF receiver equipment is highly specialized. The electronics are purpose-built, and since outdoor installation is required, they have to endure Canadian winters 鈥 heavy snow and temperatures that can drop to -60掳F at night.</p> <p>Marshall is excited to get started on the work. With COVID-19, the Canadian border is still closed to most travel, so his lab is currently working on improving the VLF receiver design.</p> <p>The grant, worth about $600,000, will run for five years.</p> <div class="ucb-box ucb-box-title-hidden ucb-box-alignment-right ucb-box-style-fill ucb-box-theme-darkgray"> <div class="ucb-box-inner"> <div class="ucb-box-title"></div> <div class="ucb-box-content">Bob Marshall was one of 12 NSF CAREER Award winners in the 兔子先生传媒文化作品 college of engineering in 2021.<br> <a href="/engineering/2021/04/19/college-celebrates-12-nsf-career-award-winners-2021" rel="nofollow">Check out more of their research.</a></div> </div> </div> <p>鈥淏eing selected is empowering.

The FPGA expands on an earlier design Marshall previously worked on for the VPM CubeSat, an Air Force Research Laboratory project expected to launch later this year.</p> <p>While not part of the CANVAS mission, the wave maps it generates could eventually be used to help predict changes in Earth鈥檚 Van Allen radiation belts, an area of dynamic populations of charged particles that encircle our planet.
