Gas sensing in remote regions and in our oceans is becoming increasingly important for developing mitigation strategies and policies in response to global warming. This project will develop a monitoring strategy based on inexpensive, passive and biodegradable sensors, which can be distributed in the environment without detrimental effects, combined with optical spectroscopy. The sensors are placed in corner-cube arrays that acts as retroreflectors, whose signals are remotely detected by spectroscopic interrogators that can be placed in stationary base stations or on movable platforms, e.g. airplanes and drones. The research has a dual focus of developing the sensor technology and the deployment strategy.
