Applications of real-world gas detection: Airborne Natural Gas Emission Lidar (ANGEL) system

An airborne DIfferential Absorption Lidar (DIAL) system was used to detect methane, propane, and light crude gas vapors during real-world collections. A series of overflights were conducted at two separate test locations (Kingsville/Corpus Christi, TX and Spencerport, NY). DIAL, digital orthophotogr...

Description
Summary:An airborne DIfferential Absorption Lidar (DIAL) system was used to detect methane, propane, and light crude gas vapors during real-world collections. A series of overflights were conducted at two separate test locations (Kingsville/Corpus Christi, TX and Spencerport, NY). DIAL, digital orthophotography, and video data were collected, processed and analyzed at both sites. A new Hydrocarbon Detection Algorithm (HHDA) was developed to detect gasses other than methane. The HHDA shows promise for detecting multiple species in a local area with uniform surface reflectance or known variability.
