In the framework of the CAWSES priority program funded by the German Research
Foundation (DFG) the German contribution to the European Incoherent Scatter Radar
(EISCAT) is provided. Several research groups are actively using the possibility to obtain
data from the EISCAT experiments. Current activities of German EISCAT users include the
estimation of the spectral characteristics of polar mesosphere summer echoes observed at
VHF and UHF frequencies and the estimation of microphysical parameters of mesospheric ice
clouds derived from multiple frequency radar soundings. Furthermore, the characteristic
features of the ionosphere and thermosphere in the cusp region were observed during a
combined CHAMP-EISCAT campaign simultaneously and electron densities measured with
EISCAT are compared to modelled data using HAMMONIA. The overview summarizes the
contributions of EISCAT measurements to the atmospheric and ionospheric research activities
in past few years and outlines the ongoing research.
