Abstract: Atmospheric Soundings are measurements of the vertical profile of temperature, humidity and pressure. They are used to determine atmospheric instabilities and to locate temperature inversions or wet layers in the atmosphere. During a ski race, meteorologists often face the problem to forecast the building and dispersal of upslope fog. Therefore a temperature, moisture and air pressure measurement device was installed at the gondola, which starts in Schladming at 751 m a.s.l. and reaches the summit Planai at 1825 m a.s.l. The gondola was in operation from approx. 6 a.m. until 18 p.m. and provided a vertical profile every 15 minutes. One big problem was the altitude shift in temperature and humidity measurements, because of the motion of the gondola with a velocity up to 20 km/h. This problem was solved by building the average of an ascent and descent of the gondola and by interpolating this data with a Biliniar Akima algorithm. In this article the sounding output is compared with stationary weather data and the benefits as well as problems are outlined by describing special weather situations during the FIS Alpine World Ski Championship 2013 in Schladming.
