Unique Polar Processes

Oct. 4, 2017

This <5 minute video describes sea ice and land ice processes that are unique to polar regions. Key take-home messages: Melting land ice raises sea level and is irreversible on human timescales. Melting sea ice does not raise sea level and is reversible on human timescales.

Scientists brave Hurricane Harvey's fierce winds and pelting rain—Irma is next

Sept. 8, 2017

"People just grabbed whatever they could carry and went," said atmospheric scientist Josh Wurman, director of the Center for Severe Weather Research (CSWR) in Boulder, Colorado. Wurman should know. He and scientist Karen Kosiba, also of CSWR, were running the wrong way, heading for ground zero, where Harvey's fury would roar onshore. They weren't alone. A National Science Foundation (NSF) Doppler-on-Wheels (DOW) was with them.

ATOC Solar Eclipse Observations

Aug. 25, 2017

Dr. John Cassano has posted a couple of plots showing the temperature and solar radiation observed by the ATOC weather stations during the eclipse on Monday. I've also posted a video of the total eclipse as seen from Douglas, WY and a couple of satellite animation perspectives of the eclipse on my weather web page at http://atoc.colorado.edu/~cassano/weather/201708_eclipse/index.html .

Dinosaur-killing asteroid could have thrust Earth into 2 years of darkness

Aug. 21, 2017

Tremendous amounts of soot, lofted into the air from global wildfires following a massive asteroid strike 66 million years ago, would have plunged Earth into darkness for nearly two years, according to a news release from the National Center for Atmospheric Research (NCAR). This event would have shut down photosynthesis, drastically cooled the planet and contributed to the mass extinction that marked the end of the age of dinosaurs.
