  • The data consists of 30 minute observations recorded by an automatic weather station (iWS 18) in Cabinet Inlet on Larsen C Ice Shelf on the Antarctic Peninsula. The iWS consists of a custom-built weather station unit, assembled at the Institute of Marine and Atmospheric research Utrecht (IMAU). There are sensors for air temperature, surface air pressure, relative humidity, as well as a GPS, an acoustic snow height sensor, an ARGOS communication antenna, and three Lithium batteries that fuel the unit when solar radiation is absent. The unit is complemented by a propeller-vane Young anemometer measuring wind direction and speed. Additionally, all radiation fluxes are measured with a Kipp and Zonen CNR4 radiometer. This dataset runs from 25 November 2014 to 13 November 2017. Funding was provided by the NERC grant NE/L005409/1.

  • 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.

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.

  • Weather Research and Forecasting (WRF) model output for Larsen Ice Shelf run at 4km resolution. Modelling was carried out to support the Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project during the 2010-2011 field season.

  • 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).

  • Dew-point measurements were made using a Campbell Scientific Dew point hygrometer. The measurements were taken from samples collected on the roof of the FAGE container. The dataset provide dew point in degrees C at one minute averaging periods. The work was carried out at Halley Station in 2005, as part of the CHABLIS project (Chemistry of the Antarctic Boundary Layer and the Interface with Snow). CHABLIS ran from 2001-2006.

  • Meteorological data acquired by Automatic Weather Station (AWS) located in the region of subglacial Lake Ellsworth. Data recorded includes wind speed, wind direction, temperature, pressure, humidity, and solar radiation.
