Is it possible to access weather balloon data (temperature, moisture and wind) on your web site?
Upper temperature soundings are available in aerological diagram format via the 'Aviation Observations' tab on the menu in this site.
Is there information on this site that helps explain the Aerological Diagram?
Brochures on Vertical Stability of the Atmosphere and The Skew T-Log P Aerological Diagram in the Reference Material section of the Knowledge Centre help explain the Aerological Diagram.
