  • LOPAP HONO - In this work the technique for atmospheric HONO and HNO3 measurements is based on aqueous scrubbing followed by the sample derivatization to a highly light-absorbing azo dye, which is then detected with a long path absorption photometer (LOPAP) [Lee and Zhou, 1993; Heland et al., 2001; Huang et al., 2002; Zhou et al., 2002a; Kleffmann et al., 2002].
