When most people think of ozone, too much hairspray and a hole in the atmosphere over Antarctica might come to mind. But in Utah, it's something we actually interact with on a much more frequent basis.

“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.
