Sensitivity of aerosol concentrations and cloud properties to nucleation and secondary organic distribution in ECHAM5-HAM global circulation model

P ¨oschl, U.: Aerosol- and updraft-limited regimes of cloud droplet formation: influence of par- ticle number, size and hygroscopicity on the activation of cloud condensation

Model intercomparison of aerosol number and aerosol size distributions are lacking but are more relevant for evaluating CCN predictions in global aerosol microphysics models, and is

Never- theless, some general observations can be made on the global mean importance of different parameters (Fig. 8), the rank order in terms of global mean σ CCN /µ CCN in July is

A nucleation scavenging scheme that diagnoses cloud scavenging ratios for aerosol mass and number distributions based on cloud droplet and ice crystal number concen- trations has

present, the high concentrations of fine aerosol (PM 2. 5 ) and the resulting large numbers of Cloud Condensation Nuclei (CCN) had a strong impact on clouds and microphysics,

Weekly cycles have been analysed in surface observations of sulfur dioxide and sul- fate concentrations, satellite observations of aerosol optical depth, cloud properties (cloud

We use a global aerosol microphysics model to estimate the effect of particle formation through activation nucleation in the boundary layer (BL) on cloud droplet num- ber

The well- predicted aerosol quantities, such as aerosol number, mass composition and optical properties, and the inclusion of full aerosol-cloud couplings lead to
