Radiosondes (Windsond, Sparv Embedded AB) were started in Davos Wolfgang (LON: 9.853594, LAT: 46.835577) to report height profiles of pressure, relative humidity and temperature at specific days. In addition to regular launches of radiosondes, sondes were attached to HoloBalloon to report the ambient conditions of the in-situ measurements. Further profiles of meteorological measures were recorded at HoloGondel which was installed at the gondola moving between Gotschnaboden and Gotschnagrat at 2285 m a.s.l.
