* Field and laboratory deployable with no consumables
* Installed and operational in minutes
* Rugged and unaffected by changes in ambient temperature

Organizations seeking to understand global warming must consider a wide range of factors, including measurement, modeling, protocols and international agreements, as well as local, national and global verification. Specifically, localized greenhouse gas flux measurements are aimed at quantifying the terrestrial contribution to total global greenhouse gas emissions. For any model, the most fundamental component is accurate measurement of the three principal greenhouse gases, CO2, CH4 and H2O.

The Picarro G2301-f is ideally suited for this task. It is the only multi-species instrument that combines the high-speed required for Eddy Covariance flux measurements with the unmatched long-term stability necessary for background concentration measurements. Its compact, portable chassis ensures the G2301-f operates equally well in the reference laboratory, as a portable spot measurement tool, or remotely as an unattended continuous monitoring station. The Picarro analyzer combines parts per billion sensitivity with the dynamic range necessary to measure undiluted ambient atmospheric levels of these species. Further, because it is a fully self-contained, rugged instrument with no moving parts, the G2301-f can operate for months in the field without the use of calibration gases.

The G2301-f analyzer is based on WS-CRDS technology, ensuring there is no crosstalk between the CO2, CH4 and H2O detection channels, and all three channels are unaffected by changes in other gas species. Also, data are immune to changes in ambient temperature and pressure.
