Aerosol characteristics observed in southeast Queensland and implications for cloud microphysics

Observed impacts of vertical velocity on cloud microphysics and implications for aerosol indirect effects

[1] The simultaneous measurements of vertical velocity and cloud droplet size distributions in cumuli collected during the RACORO field campaign over the Atmospheric Radiation Measurement Program’s Southern Great Plains site near Lamont, Oklahoma, US, are analyzed to determine the effects of vertical velocity on droplet number concentration, relative dispersion (the ratio of standard deviation ...

Black carbon radiative heating effects on cloud microphysics and implications for the aerosol indirect effect: 2. Cloud microphysics

This work examines the effect of black carbon (BC) radiative heating on cloud droplet formation. Changes in cloud droplet concentration and cloud albedo due to the presence of black carbon are computed for different cases of aerosol size distributions, meteorological conditions, BC mixing state, and aerosol composition. We examine the effect of three new mechanisms (that result from BC heating)...
