Air

When Professor Asmeret Asefaw Berhe arrived at UC Merced in 2009, she and her husband, Professor Teamrat Ghezzehei, were leaving major research institutions to join a brand-new campus in California’s Central Valley. It was a leap of faith — one made easier by the Sierra Nevada Research Institute.

As nations cut emissions that once fueled urban smog, scientists are discovering unexpected chemistry taking place in the atmosphere.

UC Merced Professor Xuan Zhang is leading a project to uncover how these chemical shifts could affect the air we breathe and the climate. The project is supported by a National Science Foundation CAREER Award.

Zhang is the 43rd researcher from UC Merced to earn a CAREER award from the NSF.

As the Hellman Fellowships celebrate their 30th year, three more researchers, one from each of UC Merced’s schools, have joined the prestigious ranks of recipients.

Electrical engineering Professor Qian Wang, sociology Professor Meredith Van Natta and Earth systems Professor Adeyemi Adebiyi will receive funding through their fellowships for projects they have proposed.

An average of more than 1 million acres of idled farmland a year is a significant contributor to a growing dust problem in California that has implications for millions of residents’ health and the state’s climate.

People don't think about dust much until it's time to clean the house, but a new report by UC researchers could raise awareness of the growing threat of dust and dust storms.

Dust affects everything from cardiovascular and brain health to traffic collisions and agricultural yield. “Beyond the Haze: A UC Dust Report on the Causes, Impacts, and Future of Dust Storms in California” details the wide-ranging impacts of dust on health, public safety, the environment and California's economy.

Pictures accompanying Professor John Abatzoglou's presentation on the 2025 fire season were blurry. That was intentional, he said, because so much about wildfire is unpredictable.

"There's a lot that we know, and a lot we don't know," he said.

Faculty members at UC Merced are taking the lead on four Multicampus Research Program Initiatives (MRPI), working with colleagues around the University of California system to address challenges around labor and agriculture, active matter, Indigenous health and fusion energy.

A major study publishing Friday in Science reveals that carbon dioxide emissions from forest fires have surged by 60% globally since 2001, and almost tripled in some of the most climate-sensitive northern boreal forests.

Scientists, policymakers and concerned community members will gather at UC Merced this week to compare notes and chart new directions to improve air quality and public health in the San Joaquin Valley.

When the city of Fresno and the San Joaquin Valley Air Pollution Control District wanted specifics about the impacts of truck traffic on the health of some of the city's most vulnerable residents, officials turned to UC Merced's Community Labor Center (CLC) and public health Professor Sandie Ha.
