Category 1: Peer-reviewed literature

Dimethyl sulfide (DMS) and methanethiol (MeSH) are biologically co-produced marine volatile sulfur compounds, which play a critical role in climate-cooling aerosol formation. The spatio-temporal distributions of MeSH are poorly constrained, especially over the Southern Ocean.

The ACCESS-AM2 climate model underestimates aerosol concentration in the Southern Ocean; improving aerosol representation could be problematic for the global energy balance Atmospheric Chemistry and Physics, 2025 (Ref: 17410)

Category 1: Peer-reviewed literature

The interaction of natural marine aerosol with clouds and radiation is a significant source of climate model uncertainty. The Southern Ocean represents a key area to understand these interactions, and a region where significant model biases exist.

Cloud condensation nuclei (CCN) play a fundamental role in determining the microphysical properties of low-level clouds that are crucial for defining the energy budget over the Southern Ocean (SO). However, many aspects of the CCN budget over the SO remains poorly understood…
