Short summary
Air pollution from fine and coarse particles is a major environmental issue in China, but their vertical and temporal changes are poorly understood due to insufficient long-term observations. This study shows that two major types of particles display clear differences with height and season, each having its own distinct characteristics using several years of continuous radar observations in Hefei. The radar data also indicate that these particles spread through the atmosphere differently.
