This display plots a map of weather balloon or radiosonde observations by selecting a level in the atmosphere to display the data at. Note that the pressure level (in units of millibars) goes down as you go up in height. Generally, the LC-130 aircraft fly at 500 to 400 millibars. This display shows the temperature and dew point (both in degrees C), winds (in knots), the geopotential height (in meters), and the WMO identification number.

The following comprise our available Skew-T log-P diagrams and Hodographs of the weather balloons launched from around Antarctica updated every 3 hours showing data the most recent of two launch times at 0 and 12 UTC. Some stations will not have data available or will be available 6 or 9 hours after observation time. The Skew-T chart displays a profile of temperature, dewpoint and winds from the manditory levels in the balloon flight. The Hodograph displays the winds as a radial chart from the manditory levels in the balloon flight.
