AIM Observations

HiWind (link):

HiWind is the first balloon borne Fabry-Perot interferometer designed to measure summer time polar cap thermospheric neutral winds. HiWind was launched June 14, 2011 from Kiruna, Sweden. The project is supported by NASA grant NNX08AV35G from Geospace Science Program (part of Heliophysics Research program). For more information please contact principal investigator Qian Wu (

Early Polar Cap Observatory (EPCO) and the Fabry Perot Interferometer (FPI) at Resolute Bay:

Resolute base photographResolute, Canada (75N) is the site chosen for the deployment of the National Science Foundation Advance Modular Incoherent Scatter Radar (AMISR). AMISR is a state of the art phase array radar, which allows fast electronic steering of the radar beam to track fast moving auroral features. HAO operates a Fabry-Perot Interferometer at EPCO to measure mesosphere and thermosphere neutral winds and temperatures in support of the AMISR project. Resolute is located deep inside the polar cap, which is an ideal location for study of the magnetosphere and ionosphere interaction. Resolute FPI data are available from the CEDAR database. The National Center for Atmospheric Research is operated by the University Corporation for Atmospheric Research under sponsorship of the National Science Foundation. The Fabry Perot Interferometer operation is supported by a NSF Grant ATM 0334595.
