| Abstract: | Vertical concentration profiles for NH3, HNO3 and HCl-gas and for NH4+, NO3?, SO2?4, Cl? and Na+ aerosol were obtained from a meteorological tower in the central part of the Netherlands. An upward NH3 flux of 0.12 μgm?2 s?1 was calculated from the NH3 profiles and meteorological data. From the HNO3 profiles a maximum HNO3 dry deposition velocity of 4 cm s?1 was calculated. Good agreement was found between the measured concentration products NH3](g) × HNO3](g) and the theoretical values at temperatures above 0°C and relative humidities below 80%. In other cases, higher NH3 and/or HNO concentrations in the gas phase were measured than theoretically predicted. |
