Abstract: The atmospheric ice nuclei (IN) concentrations near the ground were measured in atmospheric composition station using an improved Bigg mixing cloud chamber in Fushun during May to November, 2011. The features of the diurnal and seasonal IN concentrations were analyzed and the effects of meteorological elements such as wind, air pressure, air temperature, humidity and weather situation etc. on IN concentrations were discussed. The results show that the average IN concentrations is about 30 L-1 (when activation temperature reaches -20 ℃) in Fushun during the observational stages. With the decline of activation temperature, the IN concentrations increase exponentially. The meteorological factors have a certain influence to the IN concentrations, and the influencing extent is different in the different seasons.
