Description
Summary:This paper describes theoretical calculations of atmospheric ammonia profiles during precipitation events. The PLUVIUS reactive storm model (Hales, 1982, Atmospheric Environment 16,1775–1783) was used in a simplified form relevant to this specific system. Calculated NH 3 profiles for dry atmospheres were consistent with distributions previously reported in the literature. NH 3 profiles in the gas and cloud phases, following a simulated convective storm, showed large variations with height. These variations are strongly dependent on storm duration. In some cases, NH 3 gas concentrations were depleted by more than 50% by the precipitation scavenging process. Modeled NH 3 gas profiles regenerate slowly with time after storm termination.
