In this study, numerous approaches used in research from 2009 to 2023 are discovered by studying several research papers. A lot of studies have concentrated on characterizing particulate matter chemically and by measurement. The bulk of studies, however have indicated that PM2.5 particles are significantly more significant because they are the root of global climate changes, health issues and visibility impairment. Recent research confirms that the duration and intensity of rain, particularly in the below-cloud scavenging process have an impact on scavenging of particle aerosols and can change the air quality index. According to some researchers, wet scavenging has been a popular method for eliminating particulate matter on a worldwide scale recently and precipitation can reduce particulate matter concentration.
