Heterogeneous Uptake of HNO3 on CaCO3: Determination of the Gas-Particle Reaction Probability as Function of Relative Humidity
EMSL Project ID
25609
Abstract
The proposed work will provide an accurate measurement of the heterogeneous reaction probability for HNO3 on CaCO3 and its dependence on relative humidity. The value of γHNO3 (uptake coeficcient) determined from this work can then be used in atmospheric chemistry models to better assess the impact of heterogeneous reactions on mineral dust surfaces on the overall chemical balance of the atmosphere.
