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.
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.
Automatic data loggers are often used to monitor environmental variables such as temperature (of air and soil), humidity, wind speed and radiation in microclimates where experimental or ecological studies are being carried out. Some loggers are only in operation for a few weeks or months while others have been run for several years. Loggers have been sited in a wide variety of locations from the sub-Antarctic (South Georgia), South Orkney Islands (Signy) various Peninsula sites (as far south as Alexander Island - 70S), and some continental localities (e.g. Victoria Land). These form an important data resource to the climate conditions experienced by Antarctic terrestrial organisms. Various types of logger are used. Sensors tend to be deployed at or near ground level and in and around particular types of vegetation, or other experimental sites, such as cloches. Loggers used include Grant, Delta-T, Campbell and Squirrels. Victoria Land data for Kay Island and Edmonson Point in 1995 and 1996 was collected under the BIOTEX 1 experiment of the SCAR BIOTAS (Biological Investigations of Terrestrial Antarctic Systems) Programme.
