The BAS Meteorological Database provides access to a range of
observations from Antarctic stations.
Surface SYNOP data are available for 8 stations, namely Deception
Island, Grytviken, Adelaide Island, Signy Island, Port Stanley,
Rothera Point, Halley (formerly Halley Bay) and Vernadsky/Faraday
(formerly Argentine Islands). All but the first 3 stations are
operational. Those in operation have been located at the same or a
nearby site up to the present and, apart from Rothera Point, Signy and
Adelaide Island, have consistently completed observations at 3 hourly
intervals. Data for Signy have been intermittent and irregular until
recently and should be treated with caution from 1984 onward owing to
the absence of a trained meteorological observer at the site at most
times.
Meteorological observations are still undertaken by the Meteorological
Office at Mount Pleasant airport (MPA), Falkland Islands, but data are
only available for Port Stanley.
The most important change in observing practice has been the
changeover from manual to automatic observing systems to perform many
routine synoptic observations. This change occurred in the mid-1980s
at Halley and Faraday and more recently at Signy Island and Rothera
Point, and involved the deployment of SCAWS (Synoptic and
Climatological Automatic Weather Station) which was replaced in 1992
by MAWS (Modular Automatic Weather Station). Apart from standard
checks to the data, e.g. for extreme values, including those due to
equipment malfunction, and incorrect codes, the experience of trained
meteorological observers in addition to further scrutiny of some of
the data suggests that the performance of automatic weather stations
and instruments after initial installation has been
satisfactory. Instruments are regularly and frequently
calibrated. Regular on-site monitoring of the performance of SCAWS and
MAWS by observers, including comparisons with measurements from
standard meteorological equipment, also appears to have prevented
systematic errors in measurement.
