Zusammenfassung |
The NO-NO2 system was analyzed in different chemical
regimes/air masses based on observations of reactive nitrogen species and
peroxy radicals made during the intensive field campaign MIRAGE-Mex (4 to 29 March 2006). The air masses were categorized into 5 groups based on
combinations of macroscopic observations, geographical location,
meteorological parameters, models, and observations of trace gases: boundary
layer (labeled as "BL"), biomass burning ("BB"), free troposphere
(continental, "FTCO" and marine, "FTMA"), and Tula industrial complex
("TIC"). In general, NO2/NO ratios in different air masses are near
photostationary state. Analysis of this ratio can be useful for testing
current understanding of tropospheric chemistry. The ozone production
efficiency (OPE) for the 5 air mass categories ranged from 4.5 (TIC) to 8.5 (FTMA),
consistent with photochemical aging of air masses exiting the Mexico
City Metropolitan Area. |
