| Figure 3 The dependence of trace gases on wind speed and wind direction: a NO x during the whole observational period; b O x in summer; c SO 2 in the daytime 0900-1800 LST in the fall; d SO 2 at night in the non-heating months of September and October; e SO 2 at night in the heating month of November. The criterion used to examine wind consistency was 0.9 based on 2-h moving averaged wind data. |
