USOS 2024

What: Utah Summer Ozone Study (USOS)

When: July - August 2024

Where: Wasatch Front region of northern Utah

How: NOAA CSL will carry out observations through a combination of mobile laboratory (i.e., instrumented vehicle) measurements and augmentation of fixed ground sites with research grade instruments.

NOAA CSL will conduct a study of summertime ozone in the Wasatch Front region of northern Utah in the summer of 2024. This region (population of 2.5 million and growing), exhibits regular exceedances of the National Ambient Air Quality Standard (NAAQS) for ozone. Measurements of the spatial distribution and speciation of major ozone precursors (NOx and VOCs), together with additional chemical measurements and meteorological data, will enable better understanding of the factors that lead to high ozone.
