Database of surface level atmospheric dimethylsulfide (DMS) collected for the project "The Great Barrier Reef as a significant source of climatically relevant aerosol particles"

Full description

The data provided here consists of surface level atmospheric DMS measurements collected at Heron Island on the southern Great Barrier Reef (23.44°S, 151.91°E) in January-February 2018. This data has resulted from a series of campaigns conducted on the Great Barrier Reef (GBR) to examine the significance of the GBR as a source of new aerosol particles. Accompanying the atmospheric DMS data set are one minute averaged particle number concentrations for the size range fractions 0.5 - 2.5 micron and >2.5 micron collected using a Dylos DC1700 air quality monitor. Surface level solar irradiance (300 -1100 nm) is also provided with the data collected in Jan-Feb 2018 at Heron Island.

Hilton B Swan collected the atmospheric DMS data using a gas chromatograph fitted with a sulfur-specific pulsed flame photometric detector (GC-PFPD). An auto-sampler was used with the GC-PFPD to provide continuous sampling with a 20 min cycle time.
