  • Meteorological data collected on Larsen Ice Shelf including pressure, temperature, wind speed and direction.

  • Surface meteorological data collected at the following British Antarctic Survey stations in Antarctica: Adelaide Island (1962-1976); Deception Island (1959-1967); Faraday/Argentine Islands (1946-1995); Fossil Bluff (1961-2005); Grytviken (1959-1981); Halley (1957 to 2013); Rothera (1976 to 2013); Signy (1956 to 2000). The following meteorological parameters are included in the files: Sea Level Pressure (hPa); Station Level Pressure (hPa); Temperature (Deg C); Wind Speed (knots); Wind Direction (Degrees). Observations were recorded every 3 or six hours for the first part of the record and then at hourly intervals in the later part when electronic measuring systems were introduced in the 1980s and 1990s.

  • 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.

  • High-resolution simulation of summer climate over West Antarctica using the Polar-optimised version of the Weather Research and Forecasting (WRF) model conducted at British Antarctic Survey, Cambridge, UK. Runs are conducted for summer (January-centred) 1980-2015, i.e. from December 1979 to February 2015, for December, January and February (DJF). Experiments were carried out for the NERC West Antarctic Grant (NE/K00445X/1) during 2014-2017. The project is aimed at understanding the variability and climatology over the West Antarctic ice sheet and ice shelves as well as to project the future change over the twenty-first century. The model outer domain encompasses the West Antarctic ice sheet and a large part of the surrounding ocean at 45 km horizontal grid spacing, and the nested (one-way) inner domain covers the Amundsen Sea Embayment at 15 km grid spacing. The model uses vertical eta coordinates with both domains have a model top of 50 hPa, and 30 vertical levels.
