We operate air quality monitoring sites around the region. Most of our sites are designed to monitor the meteorology and chemistry of wintertime inversions and winter ozone, so they often only operate during winter. The following is an overview of measurements we collect at these sites.
Our Horsepool site (40.143, -109.469) has operated since 2011 in an area of intensive oil and gas development in the Uinta Basin. This is our flagship site, and we have hosted many collaborative research efforts at the site with NOAA, BYU, University of Utah, and others. Our permanent instrumentation at the site measures:
- NOx with an Ecotech 9841 analyzer with a UV NO2 converter from Air Quality Design
- NOy with an Ecotech 9843
- Ozone with an Ecotech 9810
- Carbon monoxide with an Ecotech 9830
- PM2.5 with a Met One BAM 1020
- Methane and total non-methane hydrocarbons with a Chromatotec ChromaTHC with methane option
- Speciated C2-C12 hydrocarbons with a Chromatotec airmozone system
- Speciated C2-C12 hydrocarbons and C1-C3 alcohols via a custom-built canister sampling system
- Net solar radiation with a Kipp and Zonen CNR4
- Incoming and outgoing UV A and B radiation with a Kipp and Zonen UV A/B
- Snow depth with a custom-built accoustic sensor
- Gaseous mercury with a Tekran 2537, a membrane-based system for oxidized mercury developed at the University of Nevada Reno, and a gaseous mercury calibrator we developed
- Basic meteorology
We also routinely measure flux of methane, non-methane hydrocarbons, carbon dioxide, and carbonyls from snow at the site with flux chambers, and we are installing capacity to measure methane and carbon dioxide fluxes via eddy covariance with an LGR fast greenhouse gas analyzer.
We operate the Roosevelt site (40.294, -110.009) in a collaboration with the Utah Division of Air Quality, which maintains a regulatory monitoring station at the same location. The following are measured at the site:
- NOx with a molybdenum NO2 converter (DAQ)
- NOx/y with an Air Quality Design NOy converter and a Teledyne 200EU and an Air Quality Design UV NO2 converter (USU)
- Ozone (DAQ)
- PM2.5 (DAQ)
- Methane and total non-methane hydrocarbons with a Thermo 55i (USU)
- Speciated C2-C12 hydrocarbons with a Perkin Elmer turbomatrix autosampler and real time GC (USU)
- Speciated C2-C12 hydrocarbons and C1-C3 alcohols via a custom-built canister sampling system (USU)
- Net solar radiation with a Kipp and Zonen CNR4 (USU)
- Snow depth with an accoustic sensor (USU)
- Basic meteorology (DAQ)
We established the Castle Peak site (40.051, -110.019) to monitor air quality in a part of the Basin that is dominated by crude oil development. At the site we measure:
- NOx with a Thermo 42i and an Air Quality Design UV NO2 converter
- Ozone with a 2B model 205
- Basic meteorology
We operate a site in Fruitland (40.209, -110.840) in cooperation with Utah DAQ to measure ozone and basic meteorology. We also operate sites that measure ozone (with portable 2B monitors) and basic meteorology on solar-powered tripods. The number and location of these sites has changed from year to year. currently we operate one of these sites at Seven Sisters (39.983, -109.344) and another at Willow Creek (39.833, -109.583).
Mobile Emissions Measurement Laboratory
We use a mobile emissions measurement laboratory to characterize emissions of methane, carbon dioxide, non-methane hydrocarbons, alcohols, and carbonyls from various sources. The trailer is currently configured to (1) measure soil or water fluxes with up to six flux chambers at a time and (2) measure emission rates from various components of oil and gas equipment with a high-flow sampler. The trailer includes these major features:
- An LGR ultraportable greenhouse gas analyzer to measure concentrations of methane, carbon dioxide, and water vapor
- A custom high flow measurement system that handles emission rates of up to 1900 L/min. This system uses a Fox FT3 thermal mass flow meter to measures air flow and is intrinsically safe and fully grounded. It is currently configured to analyze for carbon dioxide, methane, and a suite of hydrocarbons, alcohols, and carbonyls.
- A canister sampling system to collect whole air samplers to analyze for non-methane hydrocarbons and alcohols
- A DNPH cartridge sampling system to capture samples of carbonyls
- A dynamic dilution calibration system to deliver precise, customizable concentrations of gases of interest in real time.
- A meteorological tower that is attached to the trailer and sets up in seconds
- A dynamic flux chamber system modeled after the EPA emission isolation flux chamber
