Chlorine-phase Partitioning at Melpitz near Leipzig

  • Detlev Möller

Hydrochloric acid (HCl) in the gas phase, chloride, and sodium in particle phase were measured first time with high time-resolution and simultaneously with a number of other atmospheric components (in gas and particulate phase) as well meteorological parameters during a campaign at the research station Melpitz (Germany) in summer 2006 to study the Cl partitioning. On most of the 19 measurement days the HCl concentration showed a broad maximum around noon/afternoon (on average 0.1 μg m−3) and much lower concentrations during night (0.01 g m−3) with high correlation to HNO3. The data support that (1) HNO3 is responsible for Cl depletion, (2) there is an increase in the Na/Cl ratio due to faster HCl removal during continental air mass transport, and (3) on average 50% of total Cl is being as gas-phase HCl.
