Greenhouse Gases

Now anyone can visualize greenhouse gas emissions and track them directly to source, in seconds.

Picarro is powering an emerging network of public and private GHG measurement networks across North America, Europe and Asia. Our analyzers have been designated by the World Meteorological Organization as the gold standard for high-precision GHG measurements.

By combining that technology with our intuitive P-Cubed™ cloud-based informatics platform, you can create plume maps that show the main emission sources for CO2, CH4 and N2O, with parts-per-billion resolution. From industrial facilities to whole cities, our analyzers work on any scale.

You'll get minimal drift and rugged reliability—whether you put them in one spot, drive them around in a car, or fly them overhead on a plane. Identify emission hotspots, set reduction priorities and determine the efficacy of abatement strategies with unprecedented scientific certainty.

Research Applications

Airborne greenhouse gas measurements

Researchers from NASA Ames, JPL and Japan Aerospace Exploration Agency have employed a Picarro CRDS analyzer (G2301-m) to measure vertical profiles of CO2 on a research aircraft from near ground level to 8 km above mean sea level, correlated with measurement values from the overpassing Greenhouse Gases Observing Satellite (GOSAT) and ground based CRDS measurement.

Wofsy, et al., have employed a Picarro GHG analyzer to perform high-accuracy continuous airborne measurements of CO2 and CH4 over Brazil without a drying system or any in-flight calibration gases. After corrections, the results show that the CRDS is sufficiently stable to be used in-flight without drying the air or the need for calibration; the water corrections are adequate for high-accuracy continuous airborne measurements of CO2 and CH4.

Diurnal CO2 cycle analysis at a rural site

Perez, et al., at the University of Valladolid (Spain) applied weighted average, asymmetric circular functions and conditional probability curves to CO2 concentrations recorded at three levels near surface using a GHG CRDS analyzer. Concentration duration was studied in two-hour intervals and sharp contrasts were observed between day and night, or among levels. Differences in time percentages between extreme levels provided values up to 20% during the night and around 5% during the day.

CO2 and CH4 flux measurement

Using a Picarro flux analyzer, a group of Chinese researchers have successfully quantified the flux of CO2 and CH4 in inner-Mongolian desert grassland and were equally able to quantify the contribution of livestock discharge on GHG emissions.
