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