The European Centre for Medium-Range Weather Forecasts (ECMWF) Forecast Charts are images that display type and amount of cloud, and mean seal level pressure with 12 hour accumulated precipitation measurements. The measurements are taken worldwide. The charts in this dataset are from 1st of June 2005 until the 9th of September 2005.

Near real time output from the Met Office's operational Unified Model (UM) supplied participants of the Convective Storm Initiation Project (CSIP) aimed to further the understanding of the mechanisms responsible for the initiation of precipitating convection in the maritime environment of southern England. The CSIP project aimed to understand why convective clouds form and develop into precipitating clouds in a particular location. The project was centred on the 3 GHz (CAMRa) and 1275 clear-air (ACROBAT) radars at Chilbolton and used a number of the new UK Universities' Facility for Atmospheric Measurement (UFAM) mobile instruments.
