How we measure
Instrumentation at our Benchmark Sites
Advanced instrumentation paired with soil and weather measurements to capture N2O emissions and the conditions that drive them.
Flux Gradient Field Towers
Continuous, field-scale measurements of N2O using a closed-path trace gas analyzer for N2O mixing ratio analysis.
Automated Flux
Chambers
Automated chambers provide high-frequency measurements of N2O emissions on a smaller scale.
Eddy Covarience
Systems
Equipped with a sonic anemometer and open path analyzers for CO2, water vapor, and sensible heat flux.
Soil & Weather
Sensors
Soil moisture, temperature, precipitation, and wind data to inform the interpetation of emissions data.
Regional-scale monitoring
Tall Tower
Yorkton, Saskatchewan
Co-located on a CBC broadcast tower, Canada’s first agricultural “tall” tower measures N2O concentrations across a major Prairie farming region, capturing a regional picture of emissions. These data provide an independent check on national estimates and help reveal whether mitigation practices are reducing emissions at scale.
