摘要: 利用差分光学吸收光谱仪(DOAS)进行亚硝酸(HONO)气体的测量并同时在固定的波长范围内(3 07—380 nm)反演气溶胶参数包括气溶胶的平均直径、总个数和总比表面积等. 实验结果表 明利用自测的NO2标准吸收截面可以更加准确地拟合HONO的浓度，同时在较短的 波长范围内能准确反演气溶胶参数.

Abstract: Differential optical absorption spectroscopy (DOAS) is a spectroscopic technique which can be used to monitor many kinds of air pollutants simultaneously. In th is paper, in situ measurement of nitrous acid and retrieval of aerosol parameter s in a fixed wavelength range (307 nm—380 nm) were performed with DOAS system d eveloped by our laboratory. The measurements of HONO concentration were more acc urate using the NO2 standard absorption cross section measured by our selves a nd aerosol parameters were retrieved successfully in a shorter wavelength range.
