Analysis of the Optical Characteristic of Littoral Aerosol Influenced by Typhoon
The optical characteristic of littoral aerosol influenced by typhoon is analyzed, through measuring aerosol optical thickness with sunphotometer CE317 in a Langley method in the 19th typhoon period in 2005. Aerosol is changed obviously after typhoon, the thin particle amount decreases and thick particle amount increases. Aerosol optical thickness, ngstrm parameter α and atmosphere turbidity parameter β reach to the lowest ralue of 0.132(550 nm),0.861 and 0.079 respectively. The percentage of thin particle and thick particle in a unit volume amount, the size distribution of aerosol and amount concentration of aerosol particle are measured by aerodynamic particle sizer spectrometer, which agree well with the above α,β value.
