Although this coded data is still available from three American universities it has now been replaced by a universal digital coding system so data can be shared in the same format whatever the source of the observations. This enables Synop, Metar, upperair and satellite data to be processed by a common computer system. The short wave radio transmission of Synop data was common in the 1980s from Bracknell or Paris but this is now redundant. Synop data is available as downloadable files from a number of internet sites including the College of DuPage.
