Aircraft(ER-2) and Balloon In-Situ Measurements of HC1, NO(sub 2), HNO(sub 3), N(sub 2)o, and CH(sub 4) for Testing Heterogeneous Chemistry on PSC's and Sulfate Aerosols in the 1991/92 Arctic Winter

摘要

Concentrations of HC1 measured in the 1991/3 northern hemisphere lower stratosphere from the ER-2 aircraft are significantly lower than model predictions using both gas phase and heterogeneous chemistry, but are in much better agreement with model predictions for the 1994 southern hemisphere.
