Aerosol optics model for black carbon applicable to remote sensing, chemical data assimilation, and climate modelling

Aerosol optics models are an integral part of climate and retrieval methods for global remote sensing observations. Such large-scale environmental applications place tight constraints on the affordable model complexity, which difficult to reconcile with considerable level detail that is needed capture sensitivity optical properties morphological aerosol characteristics. Here, we develop a novel core-grey-shell dimer demonstrate its potential reproducing radiometric polarimetric black carbon aerosols. The depolarisation mainly sensitive relative size monomers, while cross sections depend core-shell partitioning carbon. optimum choice these parameters fairly stable across particle sizes soot volume fraction, as demonstrated by comparison more realistic coated aggregate model.
