Abstract: A method of detecting a target gas includes the step of traversing a target area with a gas-filter correlation radiometer having a field of view oriented towards the target area. The gas-filter correlation radiometer receives reflected radiation in a passband from the target area and produces gas-filter correlation radiometer signals from the received reflected radiation. A surface reflectivity spectral profile of the target area is determined. The presence of the target gas in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.
