    Abstract: A method of detecting natural gas releases that 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 methane in the target area is then determined based upon the received reflected radiation and the surface reflectivity spectral profile of the target area.

    Abstract: A gas filter correlation radiometer mounted on an aircraft is flown over a target area. The gas filter correlation radiometer is configured to detect a gas in a vapour plume in the event of a liquid leak. The gas filter correlation radiometer uses a gas in the vapour or a gas that has a spectral band overlapping a spectral band of the vapour. The gas filter correlation radiometer uses background radiation to detect the vapour.

    Abstract: A gas filter correlation radiometer mounted on an aircraft is flown over a target area. The gas filter correlation radiometer is configured to detect ethane (C2H6) gas in the event of a gas leak. The gas filter correlation radiometer may use an ethane peak at 3000 cm-1 to detec ethane. The gas filter correlation radiometer uses background radiation to detect ethane. The gas filter correlation radiometer splits incoming radiation into two paths with different ethane path lengths, detectors on each path having corresponding pixels having collocated fields of view, the corresponding pixels being sampled simultaneously to detect ethane.
