Hadley Centre for Climate Prediction and ResearchGMSLP2 is a fully global mean sea-level pressure data set. It is a historical, gridded monthly data set covering the period 1871-1994 and the latest version, GMSLP2.1, has been developed by blending a combination of existing gridded mean sea-level pressure analyses with marine and land observations, using Laplacian interpolation techniques. A range of quality-controls was used to remove random and systematic errors from the observations. However, owing to the scarcity of reliable observed data, especially in the earlier decades, it was subsequently necessary to remove biases from the blended analyses in some areas, such as the Southern Ocean.
GMSLP2.1 has already been invaluable for atmospheric model validation purposes and in several empirica; studies, such as a joint CSIRO-Meteorological Office (UKMO) Atlas of El Nino Southern Oscillation and climate variability. A key ongoing use is in connection with atmospheric model simulations of recent climate, aimed at detecting climate change and attributing it to human activities. In addition, GMSLP is being used in connection with the 'Changes to the Climate of the UK' project.
