The Los Gatos Research (LGR) Greenhouse Gas Analyzer (GGA) is a portable analyzer suitable for in situ measurements, either airborne or ground-based. It utilizes off-axis integrated cavity output spectroscopy (OA-ICOS) technology to simultaneously measure methane (CH4), carbon dioxide (CO2), and water vapor (H2O). It can detect CH4 levels up to 100 ppm, CO2 up to 20,000 ppm, and H2O up to 30,000 ppm. The device offers a selectable measurement rate ranging from 0.01 to 1 Hz, with some models featuring a fast flow option capable of rates up to 10 Hz.
