Air Quality

Brown smoke obscures a building with the sign "...D CENTRAL BAKERY". People in masks wait in line outside. Barricades with "road closed" sign block the adjacent street.

Wildfire smoke trends worsening for Western U.S.

The warming climate has made wildfires and smoke increasingly common. Researchers in the Department of Atmospheric Sciences evaluated data from a number of sources to look at air quality trends in the West. A new paper by doctoral student Kai Wilmot with Gannet Hallar and John Lin (GCSC-affiliated faculty) and Derek Mallia (past GCSC fellow) […]

Mitchell: what happens to air quality when we stay home?

Logan Mitchell, Research Assistant Professor in Atmospheric Sciences and GCSC affiliate, monitors greenhouse gases in the Salt Lake urban region. He reports on the changes in air quality when residents have dramatically reduced vehicle trips during the coronavirus pandemic. Read about Dr. Mitchell’s preliminary findings on the Atmospheric Sciences page.


Mendoza & Lin: How Much Can Transit Improve Air Quality?

It makes sense that riding public transit is better for air quality than single riders each driving a personal vehicle. In a new study, GCSC affiliates Daniel Mendoza and John Lin, along with colleague Martin Buchert, quantify those emissions reductions. The research team analyzed rider data along with transit service schedules and routes to estimate […]


McKenzie Skiles Studies Threat to Utah’s Snow

What does the level of the Great Salt Lake have to do with skiing Utah’s “greatest snow on earth?” GCSC affiliate McKenzie Skiles, assistant professor of geography, studies snow hydrology, light absorbing particulates in snow/snow energy balance, remote sensing of the cryosphere, and cryosphere-climate interaction. Light-absorbing particulates includes dust. Dust on snow accelerates melting. In […]


Workshop on Urban Greenhouse Gas Emissions

With the support of GCSC staff, the Land-Atmosphere Interactions Research Group (LAIR) hosted the second CO2-Urban Synthesis and Analysis workshop in SLC on Oct 24-25. The workshop brought together close to 100 leading researchers and stakeholders from around the nation working on understanding and mitigating greenhouse gas emissions from cities. The University of Utah has […]
