متن کاملAtmospheric oxidation in the Mexico City Metropolitan Area ( MCMA ) during April 2003
The Mexico City Metropolitan Area (MCMA) study in April 2003 had measurements of many atmospheric constituents, including OH and HO2. It provided the first opportunity to examine atmospheric oxidation in a megacity in a developing country that has more pollution than typical U.S. and European cities. At midday, OH typically reached 0.35 pptv (∼7×106 cm−3), comparable to amounts observed in U.S....
