Our upper-air weather conditions are plotted on maps of constant air pressure from European radiosonde data. The altitude at which the particular pressure is located is reported on these maps.

Upper Air Mandatory Level Plots
Quick Links: Analysis Centre > Surface Analysis > Upper Air Analysis > Frontal Charts
The upper air maps are plotted using radiosonde which measure upper air conditions over a particular location. This includes plots of data on the standard mandatory and height levels, contours of various upper air parameters and a set of sounding plots for a number of European sites. The maps are updated once every 12 hours at approximately 0645 / 1845 UTC (0045 / 1245 EST)
