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).
-
Actinic fluxes were measured using the BAS spectroradiometer, between 7 January 2005 and 10 February 2005. Measurements taken mostly relate to down-welling flux, but the spectroradiometer was periodically inverted to record up-welling flux. 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). The dataset provides ratios given as j-values for jO1D, nitrogen dioxide (jNO2) and nitrous acid (jHONO), at approximate one-minute intervals.
-
Total peroxy radical (HO2 and RO2) measurements were made during 2005. 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).
-
Surface ozone measurements taken using a 2B-Technologies (Model 202) ozone analyzer, at CASLab (the Clean Air Sector Laboratory), Halley Station, between 2004 and 2005. The dataset lists O3 mixing ratios at 1-minute averages of 10 second data. This work was carried out 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).
-
H2O2 (hydrogen peroxide) measurements were made using a HPLC-PCD (high-performance liquid chromatograph) system, between 2004 and 2005. The 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).
-
Meteorological data were collected between Jan and Oct 2005 from a sensor positioned on top of the FAGE container. The dataset lists temperature (degrees C), relative humidity (%), pressure (mB), wind speed (ms-1) and wind direction (degrees). Data were collected at averaged one-minute intervals. 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 consists of measurements of hydroxyl (OH), hydroperoxyl (HO2), using FAGE (Fluorescence Assay by Gas Expansion) and radiometer measurements of ozone photolysis frequencies. This work was carried out between Jan and Oct 2005 at Halley Station, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).
-
Non-methane hydrocarbon (NMHC) measurements were made, using a GC-FID, between 2004 and 2005. 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).
