  • This dataset contains methane concentration measurements from the British Antarctic Survey's Halley Research Station in Antarctica. The Picarro G2301 analyser was used for the measurement of Methane and located at the Clean Air Sector Laboratory (CASLab). Data times were averaged from the 1 minute data to provide hourly data sets. The UK participation of the Methane Observations and Yearly Assessments (MOYA) project was funded by the Natural Environment Research Council (NERC, grant: NE/N015584/1)

  • This dataset contains carbon dioxide concentration measurements from the British Antarctic Survey's Halley Research Station in Antarctica. The Picarro G2301 analyser was used for the measurement of carbon dioxide and located at the Clean Air Sector Laboratory (CASLab). Data times were averaged from the 1 minute data to provide hourly data sets. The UK participation of Southern OceaN optimal Approach To Assess the carbon state, variability and climatic drivers (SONATA) was funded by the Natural Environment Research Council (NERC, grant: NE/P021360/1).

  • This dataset contains atmospheric carbon dioxide, oxygen and atmospheric potential oxygen data from the Southern OceaN optimal Approach To Assess the carbon state, variability and climatic drivers (SONATA) was funded by the Natural Environment Research Council (NERC, grant: NE/P021360/1).

  • Temperature, pressure, wind speed and wind direction from two automatic weather stations on the Brunt Ice Shelf that operated during 2015.

  • High-resolution simulations of near-surface (1.5 m) temperature and (10 m) zonal and meridional winds over the Brunt Ice Shelf in the Antarctic for the year 2015 were conducted using the atmosphere-only Met Office Unified Model by the British Antarctic Survey, Cambridge, UK. The datasets produced were necessary to place point meteorological measurements from the various automatic weather stations on the Brunt Ice Shelf into a wider spatial context by identifying spatial temperature gradients and investigating how such gradients may have affected the homogeneity of the composite Halley temperature record. The work formed part of the core science undertaken at the British Antarctic Survey.

  • A TSI CPC (Condensation Particle Counter) Model 3010 was installed at Halley''s Clean Air Sector Laboratory (CASLab), a mile from the station''s generator, in the (austral) summer of 2019/20 and began collecting data in February as a long term dataset. The inlet is a 3m length of antistatic tubing, with a portion left untethered so that it can move with the prevailing wind. This is to prevent icing of the inlet by allowing the inlet to stay out of the direct line of any snow or ice being blown around. Any movement from the wind should allow any hoar frost that builds up to fall off. The instrument was installed by Joshua Eveson and the primary contact for the dataset is Freya Squires.

  • British Antarctic Survey ozone data consist of observations made at the following stations: Halley, Antarctica, from 1956; Faraday, Antarctica, from 1964 (Faraday/Vernadsky from 1996); King Edward Point, South Georgia, from 1971 (until 1982); Rothera, Antarctica, from 1996. Observations at all stations are recorded in UTC. All observations at Halley and Vernadsky are made with the Dobson ozone spectrophotometer and are seasonal (Apr to Aug). Datasets include daily mean and monthly ozone values. Observations for ozone and nitrogen dioxide are made at Rothera using the SAOZ instrument, which can make observations throughout the year. There is also a Bentham spectro-radiometer at Rothera, which can be used to compute ozone levels. Full metadata on collection, instrumentation and calibration are available on the BAS ozone webpages.
