  • 1-hourly medians of 1-min Aethalometer data measured at 880 nm. The hourly medians are derived from the 1-min observations; missing data arise from rejection of medians where fewer than 50% of the 1-min average data were present. Observations were made at Halley research station, in coastal Antarctica, as part of the British Antarctic Survey programme of tropospheric chemistry. Observations were made throughout 2015 at the Halley Clean Air Sector Laboratory.

  • The dataset contains Ion Chromatograph analysis data (major ions from Cascade Impactor sampling, from high volume air sampling (HIVOL) and low volume air sampling (LOVOL) at Halley Station. This work was carried out between 2003 and 2005 during the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

  • Measurements of the concentrations of major ions in snow samples, Halley Station, 2004-2005. Snow was collected using surface sampling and snow pits and analysed using ion chromatography. This work was carried out at Halley Station, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).
