  • Nitrous acid (HONO) mixing ratio measurements were made between 2004 and 2005. The dataset give HONO ratios (pptv) at 15 min averaging periods. This work was carried out at the Clean Air Sector Laboratory (CASLab) at Halley Station, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

  • NOx measurements were made, using a chemiluminescence analyser, between 2004 and 2005. This work was carried out at the Clean Air Sector Laboratory (CASLab) at Halley Station, Antarctica, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

  • Concentrations of organic nitrates and selected halocarbons in bottle samples were measured using NI-GCMS. This work was carried between 2004 and 2006 at Halley Station as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

  • Peroxyacetyl nitrate (PAN) mixing ratio measurements were made, using Cryo-PAN instrumentation. This work was carried out between 2004 and 2005 at Halley Station, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

  • Ozone (O3) and nitric oxide (NO) measurements were made using TEI instruments attached to the roof of the FAGE container. The dataset provides O3 and NO mixing ratios (ppbv) at one minute averaging periods. This work was carried out at Halley Station in 2005 as part of 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).

  • Dataset showing concentrations of nitric acid HNO3 as analysed by ion chromatography. Nitric acid was sampled using the BAS denuder system at the Clean Air Sector Laboratory (CASLab), Halley Station, Antarctica, between March 2004 and March 2006. This dataset is part of the Collection of Meteorological and Atmospheric Chemistry Field Measurements taken during the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project.
