Optical Measurements of Particulate Matter in the El Paso–Juarez Region: Natural Mineral Dust and Soot

摘要

The absorbing effect of soot suppresses the daytime PBLheight and impedes its growth by heating the air above PBL.This can have serious impacts on air quality, especially in thesummer and winter seasons.14 Shallow PBL leads to confinementof the pollutant precursors and resulting in high pollutionepisodes. Therefore, ceilometer and photoacousticextinctiomers are ideal for air quality studies and can provideair quality policymakers useful information.
