The new G1301-m flight-ready trace gas analyser from Picarro is the first greenhouse gas (GHG) monitor to provide high precision and accuracy for CO2, CH4 and H2O, in operation at high altitudes.

The instrument is designed for continuous operation at altitudes up to 10,000 meters (30,0000 feet) and with climb/descent rates as high as 1 km/minute.

The analyser is also equipped to manage the rigorous vibration profiles of aircraft, ships and similar environments.

Developed and tested in close cooperation with scientists at NOAA, the Picarro G1301-m enables direct, real-time sampling and analysis in-flight, eliminating the time, cost and limited data sampling associated with traditional sample capture for lab-bound instruments. The instrument is based on Picarro’s wavelength-scanned cavity ring down (WS-CRDS) technology, proven in demanding laboratory applications and challenging field locations such as Mauna Loa and CarboAfrica (Ivory Coast).

Colm Sweeney is the lead scientist for the NOAA Earth System Research Lab Aircraft Program, at NOAA. He has participated in recent flight tests of the G1301-m analyser and explains, “Picarro’s G1301-m flight ready WS-CRDS analyser provides the pressure and temperature stability that greatly improves my ability to collect accurate vertical profiles of CO2 and other trace gases concentrations. These vertical profiles are an essential component in quantifying the net impact that the North American continent has on atmospheric concentrations of CO2.”

Mike Woelk, CEO of Picarro, added, “Our company is committed to developing simple-to-use, rugged GHG analysers to support every aspect of addressing climate change, from the most fundamental research to at-site solutions for direct source and sink monitoring and verification. We believe that it’s vitally important that these analysers use a common platform, so this must be a platform that has been rigorously designed, engineered and tested to deliver the same performance whether in a pristine lab, on a rainy, windy and exposed landfill site, or on a high-altitude aircraft.”

Just as with the company’s other WS-CRDS based products, the new analyser provides decades of linear dynamic range and is simple to both install and operate.
