Paper Abstract

Vertical concentration profiles of O3 and NO2 in the lower troposphere were measured simultaneously using a multi wavelength differential absorption lidar (DIAL) system based on a pair of Nd:YAG pumped dye lasers each capable of emitting two wavelength on alternate pulses. A mixture of Rhodamine 590 and Rhodamine 610 dyes and second harmonic generation was used to generate wavelengths 288.2 nm and 293. 5 nm for O3 measurement, and sum frequency mixing of LDS765 dye laser radiation with Nd:YAG fundamental was used to generate wavelengths 448.1 nm and 446.8 nm for NO2 measurement. O3 profiles of approximately 30-50 ppb and NO2 profiles of 0-20 ppb were obtained for vertical range 1500-2500 m. The measurement error was estimated to be < 6 ppb for 150 m range resolution, or < 0.9 ppm-m, for both O3 and NO2.
