Local Excitation and Effects of Waves on Atmospheric VErtical Structure

LEEWAVES is developed under the new Swedish national balloon and rocket programme. LEEWAVES is an additional module to the SPIDER payload and will carry four (4) falling spheres to be released from the main payload to study gravity waves in the atmosphere.

The research will be carried out as an additional module on the single stage S30 carrying the SPIDER payload in early winter 2016.

The payload will be launched in this period in coordination with the DLR, GW-LCYCLE airborne test campaign. The free falling spheres will be released, after the SPIDER FFU’s, to measure the vertical profile of the horizontal winds. The falling spheres are self-sufficient and will be recovered by helicopter for data extraction after landing with their own parachute system.

SSC is contracted for the mission

SSC is in addition providing

  • Project management
  • Service systems
  • Scientific payload support
  • System integration and testing
  • Launch service (Eurolaunch)
  • Operations

P.I. is Prof. Jörg Gumbel from the Department of Meteorology at Stockholm University (MISU)

The falling spheres and their ejection system are developed by KTH
