This is because most of the continuous records from ice-sheet weather stations are coastal, providing little information on the continental interior. This problem is by-passed in a new reconstruction of Antarctic surface temperature trends for 1957–2006, based on satellite data (with good spatial coverage for a short period) and air temperatures from weather stations (for a long timescale), blended via an algorithm that estimates missing data points in climate fields. The resulting record, more reliable than previous gap-filling exercises, suggests that overall the continent is warming by about 0.1 °C per decade, with stronger warming in winter and spring and over West Antarctica.
