| Zusammenfassung |
| North China Plain (NCP) is one of the most densely populated regions in
China and has experienced enormous economic growth in the past decades. Its
regional trace gas pollution has also become one of the top environmental
concerns in China. Measurements of surface trace gases, including O3,
NOx, SO2 and CO were carried out within the HaChi (Haze in China)
project at Wuqing Meteorology Station, located between 2 mega-cities
(Beijing and Tianjin) in the NCP, from 9 July 2009 to 21 January
2010. Detailed statistical analyses were made in order to provide
information on the levels of the measured air pollutants and their
characteristics. Gaseous air pollutant concentrations were also studied
together with meteorological data and satellite data to help us better
understand the causes of the observed variations in the trace gases during
the field campaign. In comparison to measurements from other rural and
background stations in the NCP, relatively high concentrations were detected
in Wuqing, presumably due to regional mixing and transport of pollutants.
Local meteorology had deterministic impacts on air pollution levels, which
have to be accounted for when evaluating other effects on pollutant
concentrations. Trace gas concentrations showed strong dependence on wind,
providing information on regional pollution characteristics. O3 mixing
ratio also showed clear dependencies on temperature and relative humidity. |
