A Simple Method for Evaluating Photochemical Dependencies in the Atmosphere

This work examines the photochemistry of the lower troposphere for clean high latitudes in spring 2000 during the Tropospheric Ozone Production about the Spring Equinox (TOPSE) experiment.TOPSE measurements included the short-lived quantities [OH], [HO2] + [RO2], and [NO]/[NO2] as well as those slow varying ones that, according to photo-chemical theory, control them, e.g.[H2O], [O3], [NOx], [CO], temperature T, pressure p, and photolysis rate coefficients (J-values).We examine this control using a simple scaling equation, which we term local sensitivity function (LSF), to correlate simultaneous measurements: [ ] [ ] [ ] [ ] [
