摘要：

Mixing ratios of gaseous nitric acid (ranging from 0.8 to 2.2 ppbv) were measured at the UBA station in the Black Forest, F.R.G., and (ranging from 0.12 to 0.9 ppbv) at the Dutch North Sea coast in Petten (ECN). A novel laser-photolysis fragment-fluorescence (LPFF) method was used which monitors HNO3 in air by OH fluorescence after irradiation by ArF laser light. Simultaneous measurements of HNO3, other trace species, and further parameters were additionally performed by the host institutions (UBA and ECN). The HNO3 data show variable agreement.
