title = "Preliminary analysis of winter visibility variation in Xi'an, China",
abstract = "Relationships between winter visibility variation, air pollution and other atmospheric factors, which occurred in Xi'an, China, 2011, are shown in this paper. Similar periodicities (3-4 days) were found in visibility variation, relative humidity, PM2.5, SO2, NO2. Relative humidity played an important in visibility variation, which may be resulted from high hygroscopicity. From preliminary analysis, We thought a combined effects from PM2.5 and relative humidity are blamed for the extremely low visibility events.",
