Towards a model for aerosol removal by rain scavenging: the role of physical-chemical characteristics of raindrops
[EN] A one-year study was carried out in León, Spain, in order to characterize physically and chemically the precipitation. With the aim of studying the scavenging process of atmospheric pollutants, scavenging ratio and removal coefficients were calculated through physical parameters of raindrops (o...

With the aim of studying the scavenging process of atmospheric pollutants, scavenging ratio and removal coefficients were calculated through physical parameters of raindrops (obtained by disdrometer data) and through chemical properties of aerosols. Finally, linear models for the prediction of the chemical composition of rainwater and the efficiency of the removal effect were established. In general, the rainwater was dominated by NH4+ > SO42− > NO3− in all seasons. Higher ion concentrations and conductivity and lowest pH were observed in summer, due to the low volume of rain. In winter, the high values of Na+ and Cl− in the rainwater showed the contribution from marine sources, while in summer the high concentrations of Ca2+, Mg2+, SO42−, NH4+ and NO3− reflected the contribution from both crustal and anthropogenic sources. The linear models revealed that the amount of dissolved organic carbon and of the water-soluble ions in rain samples, Ca2+, SO42−, NO3−, increases with the volume swept by the falling drops. Insoluble carbon fraction has a negative dependence with the volume swept and positive with the diameter of the raindrop. Removal coefficients are affected by the concentration in the air of each species before precipitation, the duration of the event and the time elapsed between two precipitation eventsSISpanish Ministry of Science, Innovation and Universities (Grant RTI2018-098189-B-I00), the AERORAIN project (Ministry of Economy and Competitiveness, Grant CGL2014-52556-R, co-financed with FEDER funds), the University of León (Programa Propio 2015/00054/001 and 2018/00203/001), the AEROHEALTH project (Ministry of Science and Innovation, Grant PID2019-106164RB-I00, co-financed with European FEDER funds) and the Junta de Castilla y León co-financed with European FEDER funds (Grant LE025P20).

Finally, linear models for the prediction of the chemical composition of rainwater and the efficiency of the removal effect were established.
