On August 21, outside of Lusk, Wyoming, Terry Bullett and Justin Mabie, like thousands of others across the United States, will be watching the solar eclipse cross the sky above. Totality there will last for less than two minutes, starting at 11:46 am. But Bullett and Mabie will be watching the eclipse with more than just their (appropriately protected) eyes: They’ve set up instruments in a field outside of Lusk to take research radar measurements before, during, and after the eclipse. Information captured by their instrument will help them study the ionosphere, a part of the upper atmosphere that’s critical for radio and other forms of communications.
Eclipse Will Have Atmospheric Impact
Ozone Treaty Taking a Bite Out of US Greenhouse Gas Emissions
The Montreal Protocol, the international treaty adopted initially to protect and ultimately to heal Earth’s protective ozone layer, has significantly reduced emissions of ozone-depleting chemicals from the United States. But in a twist, a new study by NOAA and CIRES scientists shows the 30-year old treaty has also significantly reduced climate-altering greenhouse gas emissions from the United States.
Soil Doesn’t Forget
Ecologists need to understand what and where soil microbes live in Earth’s ecosystems—these microorganisms can influence what can thrive above. But there’s a gap in the field: Today’s climate conditions do not fully explain the types of microbes they see. So CIRES researchers at the University of Colorado Boulder are looking thousands of years back in time—and they’re finding answers.
