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 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.
Global climate models and reanalysis products have revealed large, persistent downwelling shortwave radiation biases over the Southern Ocean and coastal Antarctica, likely caused by the incapability of models to accurately simulate frequent low-level mixed-phase clouds in these regions.
The impact that biogenic emissions have on aerosol-cloud interactions across the Southern Ocean is poorly quantified. Here we use satellite and ship observations during austral summer to study these interactions.
As a long-standing problem in climate models, large positive shortwave radiation biases exist at the surface over the Southern Ocean, impacting the accurate simulation of sea surface temperature, atmospheric circulation, and precipitation.
