Interactive comment on “Ion-mediated nucleation as an important global source oftropospheric aerosols” by F. Yu et al

1) As also the authors note, the role of ion induced nucleation and even the possible ion-induced nucleation mechanisms are somewhat unresolved. Taking this into account, the authors treat the subject from a slightly too narrow and purpose-oriented point of view. Because of these clear discrepancies between different studies, the authors should very carefully demonstrate e.g. their model calcul...

Ion-mediated nucleation as an important global source of tropospheric aerosols

Aerosol nucleation events have been observed at a variety of locations worldwide, and may have significant climatic and health implications. While ions have long been suggested as favorable nucleation embryos, their significance as a global source of particles has remained uncertain. Here, an ion-mediated nucleation (IMN) mechanism, which incorporates new thermodynamic data and physical algorit...

Interactive comment on “Potential impact of carbonaceous aerosols on the Upper Troposphere and Lower Stratosphere (UTLS) during Asian summer monsoon in a global model simulation” by Suvarna Fadnavis et al

This paper considers the impact of doubled BC and OC aerosol emissions in the South Asia monsoon region using the ECHAM6-HAM model. This model has coupling between aerosol and convective processes but lacks important indirect effects and an interactive ocean surface. The authors find a systematic positive impact of doubled BC and OC emissions on the rainfall over India and eastern China. Since ...
