Sensors on a train

For the past two years, light rail trains crisscrossing the Salt Lake Valley have done more to help the valley’s air than just keeping passengers off the road. Sensors placed on the trains by U scientists continually monitor Salt Lake’s urban air, particularly levels of carbon dioxide, methane, ozone and particulate matter. The train-mounted sensors provide repeated sampling transects across the valley, helping researchers to understand the dynamics of urban air pollution. At the American Geophysical Union fall meeting in San Francisco, Tuesday, Dec. 13, the team will present their initial results from methane measurements.
