| Abstract: | Number concentration and size distribution of atmospheric aerosols were measured in Beijing by an optical particle counter. The relationship between aerosol size distribution and relative humidity is discussed.The results show that the size distribution, diurnal variation, daily variation of atmospheric aerosols have a good relation to relative humidity and Richardson number. |

| Keywords: | Atmospheric aerosol Number concentration Size distribution Relative humidity Richardson number |
