| Zusammenfassung |
| 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 methods. These estimates are compared
with theoretical models. Other diagnostics used to support the
theoretical calculations include the new Poker Flat AMISR UHF radar
near HIPAS. We find that the altitude distribution of the emissions
agree with electron transport modeling with a source of accelerated
electrons located 20 km below the upper-hybrid
altitude. |
