1. An imaging system for the detection of a greenhouse gas comprising:

  • a first thermal camera for generating a static image comprising;

    an uncooled thermal detector; and

    a first spectral filter in an optical path for passing wavelengths within an absorption range of the greenhouse gas;

    a second thermal camera for generating an additional static image comprising;

    another uncooled thermal detector; and

    a second spectral filter in another optical path for passing wavelengths outside of the absorption range of the greenhouse gas, wherein the second thermal camera is aligned with the first thermal camera, and wherein the first and second thermal cameras are operative to co-collect long exposure images; and

    a robotic platform, coupled to the first and second thermal cameras, for moving the first and second cameras to facilitate detection of the greenhouse gas in a scene, wherein the greenhouse gas is detected based on the static image, the additional static image, and a difference between the static image and the additional static image.
