Ground-mobile and airborne carbon dioxide laser systems were developed to measure vapor clouds using differential absorption lidar DIAL techniques. Field testing with the ground-mobile lidar detected a vapor cloud at 7 km using the return signal from a topographic target at a range of 8.5 km. Range-resolved detection enabled mapping of vapor cloud concentration to a range of at least 1 km. The airborne lidar mapped vertically integrated, cross-cloud gas concentrations at 3 km and detected vapor clouds 7 km downwind from the vapor source. Keywords Standoff detection, Remote detection.
