Emerging Technologies
An aircraft based active differential absorption technique for determining changes in the column integrated concentration of carbon dioxide in the the atmosphere. operates at a 2 micron wavelength that enables the column to be weighted close to the surface. Uses nadir pointing lasers reflected off the Earth's surface. Instrument is eye safe at all ranges. Requires a nadir viewing port with a clear aperture of ~ 30 cm diameter. instrument is currently flown on a Twin Otter aircraft but can be adapted to other aircraft. Modular design accomodates easy integration and deintegration (4-6 hours for the Twin Otter). Limited number of aircraft check-out flights and measurement not yet validated against accepted in-situ standards as of 4/8/2007.

Current aircraft instrument is a first generation instrument but engineered to be robust. Goal of aircraft instrument is to validate the approach for an eventual space-based instrument deployment.
