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)
