  • Meteorological data measured by the Meteorological Airborne Science INstrumentation (MASIN) onboard the British Antarctic Survey Twin Otter aircraft in the region of 67 degrees South on the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project (2011). The MASIN Twin Otter aircraft (VP-FAZ) fitted with atmospheric instruments flew 22 flight, lasting in total around 78 hours. During the intensive observing period from the 11th January to 5th February two strong westerly events took place (26-28th January and 4-5th February). Six flights were flown during the earlier event and five in the second. Easterly winds were experienced more often than westerlies and the remaining OFCAP flight were used to observe easterly flow events. The flights normally consisted of an ascent on the west of the Peninsula, a transit across Peninsula at around 3000m altitude(often close to 67S - the line of AWSs but sometimes at 68S) and then a descent to the surface on the eastern side. In westerly event the aircraft would sample the detailed structure of the wind and temperature on the east of the Peninsula, while for easterly events more measurements were made on the west.

  • Ground-based meteorological data from Automatic Weather Stations (AWS) were collected to observe the atmospheric flow along a transect across the Antarctic Peninsula mountains around 67 degrees south during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project (2011). The AWS on the Avery Plateau was deployed on 10 Jan 2011 until early July 2011.

  • Ground-based meteorological data from Automatic Weather Stations (AWS) were collected to observe the atmospheric flow along a transect across the Antarctic Peninsula mountains around 67 degrees south during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project (2011). The AWS at Cole Peninsula was deployed on 21 Jan 2011 until 8 Jan 2012.

  • Radiosonde data were collected on and around the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project. Atmospheric conditions on the upwind (western) and downwind (eastern) sides of the mountains were measured using these balloon-borne radiosondes released from the Larsen Ice shelf camp and Rothera base. A total of 52 radiosondes were launched from Rothera Station during the 2010-11 field season.

  • Radiosonde data were collected on and around the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project. Atmospheric conditions on the upwind (western) and downwind (eastern) sides of the mountains were measured using these balloon-borne radiosondes released from a camp on Larsen Ice shelf camp and Rothera base. 24 radiosondes were launched from the Larsen Ice Shelf camp during the period 8-31 January 2011.

  • 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).
