In the frame of YOPP WMO Project, during the Special Observing Period lasting from 16th November 2018 to 15th February 2019, in Concordia and Mario Zucchelli stations daily soundings were executed regularly in DOMEC at 00:00 and 12:00 UTC, and in MSZ another sounding was done at 06:00 UTC and 18:00 UTC. The atmospheric parameters along the vertical profile (upper-air mesaurements) monitored are: height (gps position), pressure, temperature, humidity, velocity of wind, direction of the wind.

The RDS (VAISALA RS92) is launched into the atmosphere coupled to a balloon inflated with helium. The sonde rises with a speed of about 2-5 m / s up to a height of between 20 and 25 km. During the ascent all the parameters are acquired. The data obtained are coded both in a digital format (BUFR) and in text format and entered into the global network (GTS) of the World Meteorological Organization (WMO).
