ACE-1: Macquarie Island DMS Measurements


This dataset consists of atmospheric concentrations of Dimethylsulfide (DMS) samples taken at Macquarie Island by Hilton Swan (AGAL) during ACE-1. This DMS data defines the start/stop times (UTC) for each sample and is reported as ng/m3 and nmol/m3. Certain meteorological parameters were also recorded, from the 1-minute average Automatic Weather System (AWS), at the start of each DMS sample and these are also included in the dataset. Analytically the DMS measurements were obtained following oxidant and moisture removal from the air stream. Methylethyl sulphide was introduced with each sample as an internal standard, and a pulsed PFD was used for the selective detection of DMS. The data were processed and quality controlled during the ACE-1 field program, and the instrumentation was comparatively compared with similar instrumentation operating at Cape Grim before and after ACE-1.
