๐ŸŒง️ Development of Wet Scavenging Process of Particles in Air Quality Modeling

Image
 The wet scavenging process —often called rainout and washout —is a vital mechanism in the atmospheric world ๐ŸŒซ️. It refers to how raindrops, snowflakes, or cloud droplets capture and remove aerosol particles from the air. This natural cleansing acts as Earth’s “sky filter,” improving air purity and influencing the global climate–aerosol balance ๐ŸŒฆ️. ☔ 1. Concept of Wet Scavenging Wet scavenging is divided into two principal components: In-cloud scavenging (Rainout) ๐ŸŒง️ – Particles are incorporated into cloud droplets and later precipitate. Below-cloud scavenging (Washout) ๐Ÿ’ง – Falling raindrops collide with and capture aerosols present below the cloud base. Together, they determine how efficiently pollutants like sulfates, nitrates, and black carbon are cleansed from the atmosphere ๐ŸŒฌ️. ⚙️ 2. Process Development and Modeling In air quality modeling , representing wet scavenging accurately is a complex challenge ๐Ÿ”ฌ. Scientists develop parameterizations —mathemati...
