UK Met Office charts analyses pertaining to Mean Surface Level Pressure and 24 hour Weather Frontal Forecasting for the UK and Western Europe (see chart samples below). The charts have been produced by two systems at the Met Office and so are provided in two distinct datasets within this collection. The first set was delivered by the Met Office's GPCS Commercial Suite and covers the period 7th June 1999 to 24th June 2014. At this point the Met Office turned off that service and switched to providing images produced by the Met Office's SWIFT system using VisualWeather. These later data cover the period 30th June 2015 to present, though initially with some data gaps.
