Interdisciplinary team calls for modernized standards in national study on probable maximum precipitation

An interdisciplinary team, including CSU researchers, recommends updating the science that informs how dams and nuclear power plants are built in preparation for extreme rainfall. The design and engineering of critical infrastructure in the U.S. uses the concept of Probable Maximum Precipitation — or PMP. This represents the most unlikely but possible precipitation.   “Coming up with estimates of PMP is a major challenge: What is the best way to determine what…

Researchers highlight oil and natural gas development in Permian as key source of ozone pollution in Carlsbad Caverns National Park

New research shows that ozone concentrations at Carlsbad Caverns National Park frequently exceed Environmental Protection Agency health standards, likely due to oil and natural gas development in the Permian Basin and surrounding region. The work was led through the Department of Atmospheric Science at Colorado State University and is part of ongoing air quality research across the national park system by University Distinguished Professor Jeffrey Collett and his team. Andrey Marsavin, a Ph.D. student…
