Southern Ocean latitudinal gradients of cloud condensation nuclei [PDF]

Atmospheric Chemistry and Physics, 2021
The Southern Ocean region is one of the most pristine in the world and serves as an important proxy for the pre-industrial atmosphere. Improving our understanding of the natural processes in this region is likely to result in the largest reductions in ...

Cloud Condensation Nuclei properties of model and atmospheric HULIS [PDF]

Atmospheric Chemistry and Physics, 2006
Humic like substances (HULIS) have been identified as a major fraction of the organic component of atmospheric aerosols. These large multifunctional compounds of both primary and secondary sources are surface active and water soluble.

Limitations of passive remote sensing to constrain global cloud condensation nuclei [PDF]

Atmospheric Chemistry and Physics, 2016
Aerosol–cloud interactions are considered a key uncertainty in our understanding of climate change (Boucher et al., 2013). Knowledge of the global abundance of cloud condensation nuclei (CCN) is fundamental to determine the strength of the ...

Enhancements in Cloud Condensation Nuclei Activity From Turbulent Fluctuations in Supersaturation

Geophysical Research Letters, 2023
The effect of aerosols on the properties of clouds is a large source of uncertainty in predictions of weather and climate. These aerosol‐cloud interactions depend critically on the ability of aerosol particles to form cloud droplets.
