In order to investigate the dynamics and energetics in the polar lower thermosphere,
coordinated sounding rocket observation with the European Incoherent Scatter (EISCAT)
radar ground-based Fabry-Perot Interferometers (FPIs) was successfully conducted
during the Dynamics and Energetics of the Lower Thermosphere in Aurora (DELTA) campaign
on 13 December 2004. In the DELTA campaign, the vertical profile of neutral temperature
in the lower thermosphere was obtained by the sounding rocket experiment,
the time variations of neutral temperature and winds at the auroral emission altitudes
were measured with two FPIs, and the vertical and temporal profiles of ionospheric parameters
and neutral winds were observed by the EISCAT radar.
The results were published in a special issue of Earth, Planets and Space, Vol.58, 2006.
The DELTA-2 campaign is scheduled for Jan 2009.
Your participation and cooperation to the DELTA-2 campaign would be highly appreciated.
