Remote Gas Detection in Solid Scattering Media using Differential Absorption Lidar

Large-scale GASMAS (gas in scattering media absorption spectroscopy) measurement, which resemble multiple-scattering differential absorption lidar (DIAL) is discussed. Preliminary experiments have been performed and limitation and possibilities will be discussed. Potential future applications could include helicopter-born detection of snow avalanche victims (trapped carbon dioxide) or leaking snow-covered natural gas pipe lines.
