Simplified classification of atmospheric charged particles

One of the most important problems on the atmospheric studies is electrostatic interaction between atmospheric cluster ions and aerosol particles. Atmospheric ions are currently classified into 5 overlapping categories having mobilities ranging from 1.3 cm2 V−1 s−1 to less than 0.004 cm2 V−1 s−1. We have considered charged ultrafine aerosols and cluster ions as charged atmospheric particles. This classification can be used in the interpretation of electrostatic interactions among these particles. Attachment processes between ultrafine aerosols can be considered as recombination processes between charged atmospheric particles. Atmospheric particles are grouped into two categories, but the number of recombination and attachment coefficients is not reduced.
