متن کاملAerosol activation and cloud processing in the global aerosol-climate model ECHAM5-HAM
A parameterization for cloud processing is presented that calculates activation of aerosol particles to cloud drops, cloud drop size, and pH-dependent aqueous phase sulfur chemistry. The parameterization is implemented in the global aerosol-climate model ECHAM5-HAM. The cloud processing parameterization uses updraft speed, temperature, and aerosol size and chemical parameters simulated by ECHAM...

متن کاملUncertainty assessment of current size-resolved parameterizations for below-cloud particle scavenging by rain
Current theoretical and empirical size-resolved parameterizations of the scavenging coefficient (3), a parameter commonly used in aerosol transport models to describe below-cloud particle scavenging by rain, have been reviewed in detail and compared with available field and laboratory measurements. Use of different formulations for raindropparticle collection efficiency can cause uncertainties ...
