  • 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.

  • Ship underway data collected aboard the James Clark Ross during cruise no JR158 in 2007. Includes data from navigation and vessel-mounted ADCP (Acoustic Doppler Current Profilers). On the ship the position and observed data were interpolated to five-second records to merge the navigation with the underway data. These one-minute averages are averages over 12 of the interpolated points.

  • 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).

  • 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.

  • 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.

  • Eddy covariance (EC) observations of surface-atmosphere exchanges of sensible heat and latent heat, momentum and net ecosystem carbon dioxide exchange were measured at thirty minute resolution at three Land Surface Stations in India. The dataset includes ancillary weather and soil physics observations, as well as variables describing atmospheric turbulence and the quality of the turbulent flux observations. Meteorological observations include: the net radiation and its incoming and outgoing short- and long-wave components, air temperature, barometric pressure, relative humidity, wind speed and direction, and rainfall. Soil physics observations include: Soil heat fluxes, soil temperatures and soil volumetric water content. Observations were collected under the Interaction of Convective Organization and Monsoon Precipitation, Atmosphere, Surface and Sea (INCOMPASS) Project between January 2016 and January 2018.
