Abstract

The DIAL technique for remote monitoring of nitrogen dioxide is evaluated. A comprehensive field test and evaluation program was performed to determine the measuring capability for this pollutant. The potential sources of error are discussed and these are analyzed for the mobile lidar system used in the work. This system employs a dye laser pumped by a Nd:YAG laser; a laser source which has improved the measuring accuracy compared with earlier work on nitrogen dioxide. The accuracies are found to be good enough for measuring needs in many studies on air pollution problems. A few typical examples of measurements from the field test program are given.
