Lightning strikes may trigger short-term thinning in the ozone layer

Oct. 11, 2021

Crack! Lightning strikes are bright and loud—violent 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’s atmosphere, even affecting Earth’s all-important ozone layer. The results, published...

Mapping the energy of lightning in space

April 12, 2019

A lightning strike releases an incredible amount of energy, most of it felt on Earth’s surface, but some of that energy travels up, far above the clouds and into space, and a new satellite is being designed by the University of Colorado Boulder to map the phenomenon. Professor Bob Marshall has received a four-year, $1.2 million National Science Foundation grant to develop...

Day to Night and Back Again: Earth’s Ionosphere During the Total Solar Eclipse

Aug. 10, 2017

Assistant professor Bob Marshall wants to know more about Earth's ionosphere, and the upcoming solar eclipse is giving him a rare chance to study it. “The eclipse turns off the ionosphere’s source of high-energy radiation. Without ionizing radiation, the ionosphere will relax, going from daytime conditions to nighttime conditions and...
