DATA RESCUE DVD: 16th WMO Congress, Geneva, July 2011

Three short visualisations of what the current version of the ACRE-facilitated 20th Century Reanalysis Project (20CR) is producing. These show the global surface pressure and wind field vectors (light blue arrows) for June 1911, July 1924 and October 1987 as generated by 20CR - note that these sequences are only showing some of the global surface fields generated by 20CR, which puts out a series of weather variables at each of 28 levels in the vertical plane up through the atmosphere over the world. Red (blue) isobars are high (low) pressure regions. Coloured dots are the terrestrial and marine weather observations used to create this dynamical reanalysis (reconstruction). Light grey shaded areas are where the current lack of data is making the reanalysis uncertain, and thus present ACRE with the challenge of recovering and digitising lots more historical weather observations in order to improve and extend new versions of the reanalyses and the spatio-temporal products they will produce.
