Atmospheric physic and optical properties in Science Island, Hefei were continuously measured and statistically analyzed from January 29 to 31, in 2008. The characteristic parameters, such as temperature, relative humidity, wind velocity, turbulence refractive index constant, size distribution of aerosol particles, total number concentration, scattering coefficient and absorption coefficient were measured synchronously. Some of statistical results had distinct difference with results of routine measurement in winter. The variation of aerosol in the case was discussed.
