Interactive comment on “Size-resolved and integral measurements of cloud condensation

This paper presents measurements of size resolved and total CCN concentrations as well as aerosol composition and hygroscopicity from the high-alpine site Jungfraujoch. The authors do a good job of presenting the measurements and results and their data should contribute to the growing understanding of global aerosol hygroscopicity. However, there are a few changes which would improve the paper ...

Interactive comment on “Measured and modelled Cloud Condensation Nuclei (CCN) concentration in São Paulo, Brazil: the importance of aerosol size-resolved chemical composition on CCN

Interactive comment on “Measured and modelled Cloud Condensation Nuclei (CCN) concentration in São Paulo, Brazil: the importance of aerosol size-resolved chemical composition on CCN concentration prediction” by G. P. Almeida et al

This manuscript, as I see it, sets out to discuss two points; one of which is done better than the other. Firstly, the manuscript addresses measured and modelled CCN concentrations in Sao Paulo, Brazil. Secondly, the manuscript (as titled) stresses the importance of size-resolved chemical composition on the prediction of CCN concentrations. The first aspect is addressed quite nicely, and it no ...

Size-resolved CCN measurements

We present a method to investigate cloud condensation nuclei (CCN) concentrations and activation efficiencies as a function of two independent variables, aerosol particle size and water vapor supersaturation. To date, most ambient CCN measurements have been made as the integral (total) CCN concentration as a function of water vapor su-5 persaturation only. However, since CCN properties of aeros...
