The aerosol fraction distribution in Vietnam was determined based on monitoring data LIDAR at Hanoi and GEOS–Chem using back-trajectory statistical methods. The results showed that the aerosol concentration is the highest in northeastern of Vietnam and decreasing in the southern and western directions. Maximum of organic aerosol concentration is on the north-west. The highest sea salt aerosol concentrations are in East sea and Bengal bay. Aerosol consists mainly of sulfate, organic aerosol, and sea salt aerosol: sulfate, nitrate, black carbon, ammonium, mineral dust aerosol… The result shows the complicated aerosol distribution in Vietnam.
