Dataset
DMS concentrations in the Antarctic Peninsula
Abstract
This dataset contains the time series of dimethyl sulfate (DMS) concentrations measured at East Beach Hut near the British Antarctic Survey (BAS) Rothera station off the coast of the Antarctic peninsula since late Feb 2022, as part of the Southern Ocean Clouds (SOC) project.
The data was collected using an iDirac gas chromatograph. DMS is naturally emitted from the oceans into the atmosphere, and has a direct effect on climate through cloud formation.
This data is openly accessible for research purposes. Please do contact the authors if you plan to use this data for publications.

| Data lineage: |
Raw chromatogram from the iDirac were converted into concentrations as described in Bolas et al., AMT, 2020. Data underwent QA/QC procedures as described in Bolas et al. |
| Data Quality: |
Gas standards for DMS were prepared gravimetrically by diluting a higher concentration parent mixture (106 ± 5.3 nmol mol−1 in nitrogen, BOC) to ~12 nmol mol−1 respectively, with high-purity nitrogen (BIP+, Air Products), inside Silconert2000-treated stainless steel cylinders (RE24133-PI 500 mL sample cylinder, Thames Restek).
