Case Investigation on the Influence of In‐Snow Particles' Size and Composition on the Snow Light Absorption and Albedo

Abstract The snow physical parameters are closely related to the sizes, shapes, and chemical composition of light‐absorbing particles (LAPs). By utilizing a computer‐controlled scanning electron microscope software called IntelliSEM‐EPAS TM , we first report measured size‐resolved concentration soot, dust, fly ash in fresh (wet) aged (dry deposition) samples collected at an industrial city China during after snowfall intervals 6–8 days. Due wet scavenging by seasonal snow, soot dust absorbed 69.7% 30.3% wavelengths 550 nm, lowering albedo 0.0089 0.0039, respectively. Soot particle size increases slightly dry deposition, whereas mineral does not undergo significant shift size. These results indicate essentiality involve effects accurate in‐snow LAPs for better assessment light absorption reflectance.
