A remote sensing method is needed to supplement fixed point monitoring of leakage from pipelines and geologic reservoirs used for carbon dioxide (CO 2) storage. An experiment tested the effectiveness of thermal infrared imagery to identify plants affected by high concentrations of CO 2 released beneath a soybean canopy in east-central Illinois. Carbon dioxide gas was released for four hours at 10 m3/hr through an oscillating sprinkler simulating a point release and a 2 m perforated pipe beneath a mature, closedcanopy field. Ground-based measurements showed a 2.5°C increase in radiant temperature of CO2-affected soybeans. Aerial thermal infrared imagery showed distinct plumes of elevated radiant temperatures in the soybean field downwind of the two CO2 point-release sites six to eight hours after gas was released. Field measurements of atmospheric CO2 concentrations taken at three heights (ground, underside, and mid-canopy) guided by an air-to-ground imagery transmitter, support aerial imagery interpretations.
