Abstract This reseach compares the correlation between GPS PWV (precipitable water vapor) and PM2.5/PM10 of Beijing in 2013. It is concluded that there is a significantly positive correlation among autumn, winter and spring seasons, in which the correlation coefficient is greater than 0.5 and the best correlation coefficient amouted to 0.89. The correlation is not obvious in summer. The important factor in causing fog and haze weather is the rise of PWV in the autumn, winter and spring seasons.
