Wet removal is the primary method for the natural removal of atmospheric aerosol particles, and wet removal is a very complex process. According to the PM2.5, PM10, and meteorological data from 71 cities in China from 2016 to 2018, this study utilizes theoretical analysis methods based on the existing rainfall aerosol removal theory and real-time monitoring data to calculate the measured removal coefficient and theoretical removal coefficient for verification. According to the different rainfall intensities and rainfall times in Guilin, the measured value and the simulated value are verified, and the linear relationship obtained was Λs = 1.589*10− 5 + 0.609Λm, R2 = 0.673, and the simulated value approximated to the measured value after correction. The same method was utilized to calculate the theoretical removal coefficient of polydisperse aerosols in 71 cities across the country, and the calculation parameters of the rainfall removal polydisperse aerosol model in different regions were modified. |
