Comparing atmospheric [HO_2]/[OH] to modeled [HO_2]/[OH]: Identifying discrepancies with reaction rates

Autor: Lanzendorf, E. J., Hanisco, T. F., Wennberg, P. O., Cohen, R. C., Stimpfle, R. M., Anderson, J. G.

Reactions that inter-convert OH and HO_2 are directly involved in the catalytic removal of O_3 in the lower stratosphere and in the catalytic production of O_3 in the upper troposphere. The agreement between the measured and modeled [HO_2]/[OH] tests

During the 1993 NASA Stratospheric Photochemistry, Aerosols and Dynamics Expedition (SPADE), anomalously low nitric oxide (NO) was found in a distinct sunlit layer located above the mid-latitude tropopause. The presence of a significant amount of rea

The response of ClO radical concentrations to variations in NO_2 radical concentrations in the lower stratosphere

Autor: Stimpfle, R. M., Koplow, J. P., Cohen, R. C., Kohn, D. W., Wennberg, P. O., Judah, D. M., Toohey, D. W., Avallone, L. M., Anderson, J. G., Salawitch, R. J., Woodbridge, E. L., Webster, C. R., May, R. D., Proffitt, M. H., Aiken, K., Margitan, J., Loewenstein, M., Podolske, J. R., Pfister, L., Chan, K. R.

The response of ClO concentrations to changes in NO_2 concentrations has been inferred from simultaneous observations of [ClO], [NO], [NO_2] and [O_3] in the mid-latitude lower stratosphere. This analysis demonstrates that [ClO] is inversely correlat
