Observational Constraints on Sea Salt Contribution to CCN Over the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Earth system models exhibit persistent biases in simulating cloud condensation nuclei (CCN) over the Southern Ocean and Antarctica, largely due to inadequate representation of aerosol sources. Here, we present year‐round (January 2023–February 2024) measurements of aerosol hygroscopicity (HTDMA), particle number size distribution (SMPS), and ...

Excessive Convective Precipitation Formation Caused by Warm‐Phase Bulk Microphysical Scheme Biases: A Multi‐Platform Observational Diagnosis

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract Recent work has demonstrated that convection‐permitting models often produce a greater number of precipitating convective cells compared to radar observations. Congestus‐depth cells contribute most to the bias, which are colloquially termed “popcorn convection.” This study explores warm‐phase microphysical contributions to the bias using ...

CCN Spectral Measurements [PDF]

, 2009
Detailed aircraft measurements were made of cloud condensation nuclei (CCN) spectra associated with extensive cloud systems off the central California coast in the July 2005 MASE project. These measurements include the wide supersaturation (S) range (2-0.01%) that is important for these polluted stratus clouds.

Interpretable ensemble learning unveils main aerosol optical properties in predicting cloud condensation nuclei number concentration

npj Climate and Atmospheric Science
Variations in cloud condensation nuclei number concentration (N CCN) significantly influence cloud microphysics, yet direct N CCN measurements remain challenging.
