    • First estimates of volume distribution of HF-pump enhanced emissions at 6300 and 5577 Å : a comparison between observations and theory 

      Gustavsson, Björn Johan; Kosch, Mike; Wong, Alfred; Pedersen, Todd; Heinselman, Craig; Mutiso, Charles; Bristow, Bill; Hughes, John; Wang, Weiyuan (Journal article; Tidsskriftartikkel; Peer reviewed, 2008)
      We present bi-static observations of radio-wave induced optical emissions at 6300 and 5577 Å from a night-time radio-induced optical emission ionospheric pumping experiment at the HIPAS (Fairbanks) facility in Alaska. The optical observations were made at HIPAS and from HAARP located 285 km south-east. From these observations the altitude distribution of the emissions is estimated with tomography-like ...
