Abstract

The Differential Absorption Lidar (DIAL) experiment conducted for determining the atmospheric NO2 concentration remotely over a path length of 7574 m is described. A tunable, continuous wave Argon ion laser is used as an emitter and a 25-cm Newtonian telescope equipped with a cooled photomultplier tube is used as a detector. The long-path absorption technique followed in the present experiment involves backscattered signal strength at the ON (496.5 nm) and OFF (501.7 nm) wavelengths of the laser from a topographic target (hill) which is 3787 m away from the lidar equipment. The preliminary results of path-averaged atmospheric NO2 concentration observed on four typical nights are presented.
