Compact Low Power Sensor for Measurement of Multiple Trace Gases

Development of a highly versatile turn-key sensor for measurement of atmospheric trace gases at high accuracy is proposed. The laser-based sensor targets simultaneous measurement of carbon monoxide, nitrous oxide, and methane with 0.1 second time resolution. The sensor will be designed for use on airborne platforms, including manned and unmanned aircraft, UAVs and drones, and balloons. It will be designed for meaurements throughout the troposphere and lower stratosphere. Key specifications include compact size (volume of 72 cubic inches or less) and weight (1 kg or less), with a power requirement of less than 3 watts. The Phase I research will emphasize establishing feasibility of the approach through laboratory testing, followed by production and testing of prototype sensors in Phase II. Target markets for the sensor include NASA and other federal and international government agencies that are engaged in atmospheric research. Potential markets include wildfire monitoring as well as industrial and agricultural process applications.
