“There's nothing that's emitting ozone,” said National Center for Atmospheric Research scientist Sam Hall. “It's formed secondarily, and it's bad for human health. It's bad for crops. It makes your car rust faster. It has a lot of side effects because it's so potentially reactive, especially in the presence of sunlight.”

Hall is part of a team studying the formation of ozone in the atmosphere above the state through the end of August.

On March 13, Pieternel Levelt (far right), an associate director of the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), received the 2026 Snellius Medal. The Snellius medal is a prestigious award that is only given once every ten years by the Dutch Society for the Promotion of Natural Sciences, Medicine, and Surgery.

A research team led by the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR) has published a foundational inventory of emissions produced by structures destroyed by fires in the wildland-urban interface (WUI).
