Met Office MSLP Charts images 1999-2014 from the Met Office's GCPS Commercial System

UK Met Office charts analyses pertaining to Mean Surface Level Pressure and 24 hour Weather Frontal Forecasting for the UK and Western Europe. The charts in this dataset have been produced 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 (available as part of a separate dataset).
