Use of the Long-Wavelength Range for Remote Sensing of Atmospheric Aerosols

The results of laboratory experiments on recording the backscattered IR laser radiation from aerosol particles which contain organic impurities are presented. The studies were performed at the laboratory test bench according to the lidar sensing scheme along a controlled optical path. Water aerosol and water solutions with organic impurities (tryptophan, isopropyl alcohol, glycerin, and nicotinamide adenine dinucleotide (NADH)) were used as model media. A possibility of using IR lasers with frequency scanning for remote sensing of atmospheric organic aerosols is shown.
