Data collected by the MOSAiC expedition to the central Arctic (shown) and analyzed by McKelvey engineers revealed blowing snow as a previously unaccounted for source of sea salt aerosols, impacting Arctic climate models. Photo by Matthew Shupe, University of Colorado

Blowing snow contributes to Arctic warming

Atmospheric scientists led by Jian Wang discovered abundant fine sea salt aerosol production from wind-blown snow in the central Arctic, increasing seasonal surface warming.

To conduct a comprehensive analysis of what makes up wildfire smoke plumes, Rajan Chakrabarty’s team spent 45 days traveling to different wildfire locations in the western United States where they sampled gaseous smoke and aerosol species and analyzed their chemical and optical properties. This research was conducted as part of the Fire Influence on Regional to Global Environments and Air Quality (FIREX-AQ) field campaign, a joint venture led by NOAA and NASA.

A team of researchers at the McKelvey School of Engineering and the School of Medicine has developed a proof-of-concept air quality monitor that can detect live SARS-CoV-2 virus in indoor environments. The monitor uses a biosensor made with nanobodies that is integrated into an air sampler that operates based on the wet cyclone technology, pictured above. (Image: Joseph Puthussery)

Air monitor can detect COVID-19 virus variants in about 5 minutes

Proof-of-concept device could also monitor for flu, RSV, other respiratory viruses.
