英文摘要	This paper employed ground-based measurements, multiple satellite observations, NCEP reanalysis data, meteorological sounding data and Modeled HYSPLIT4backward trajectory results to analyse the pollution characteristics and forming process of haze pollution in Zhongmou, a rural site located in the central North China Plain. The Comprehensive observation campaign lasted from December 13th, 2014 to January 16th, 2015 and a total of five haze pollution episodes were captured Haze days accounted for 82% of the total number of days, while heavily polluted days (Class V and VI based on AQI level) accounted for 46%. The ground-based observations showed that: 1) the concentrations of PM and SO2, NOxwere highly correlated, 2) fine particulate matters were dominant among the ground-level pollutants, 3) and the secondary aerosols transformed from gaseous pollutants accounted for a predominant fraction of fine particles. CALIPSO and AMPLE vertical detection data showed that thick haze clouds were dominated by floating dust in the middle and upper layer, and coarse dust particles were prevalent over North China Plain, which accounted for a predominant fraction in the columnar optical volume. Based on meteorological sounding data, the atmospheric stratification of the planetary boundary layer (PBL) was stable, suppressing air turbulence in PBL and favoring formation and maintenance of haze. Meteorological data also showed that near-ground wind speed and direction had a great influence on haze maintenance and dissipation; High-level wind field data indicated that the first haze was influenced by floating dust from the northwest, and the fifth episode was influenced by water vapor from the south. By tracking the 100m air mass using HYSPLIY4model, the low-altitude pollutants were transported from northwest and northeast. The contribution from northeast, accounting for almost 14%, passed Hebei and Shandong province, while short distance transportation traces were mostly from Zhengzhou and Luoyang, accounting for almost 33%. © 2016, Editorial Board of China Environmental Science.
