Air Quality Monitoring

 

mobile air quality monitoring station

The Wyoming Department of Environmental Quality’s Air Quality Division placed a mobile air quality monitoring station on the National Elk Refuge in August 2018. It’s one of three mobile monitoring sites across the state and will be here until August 2019.

Robb Sgroi, the Land Resources Specialist for Teton Conservation District, serves as the site operator for the station. He keeps the site functioning and performs monthly instrument checks. The site is subject to challenges including power surges that can damage equipment, instrument failures, and leaking gas lines. We work with the Wyoming Department of Environmental Quality to diagnose and repair problems with software and hardware. The monthly site visits involve running tests and checking instruments to ensure instruments are taking correct readings. To learn more about Robb’s regular checks, read this blog entry.

In addition to measuring standard meteorological parameters like wind speed and direction, temperature, precipitation, and humidity, the mobile station also measures ozone, oxides of nitrogen, sulfur dioxide, hydrocarbons, and particulate matter .
