dc.description.abstract | Natural enhancements in the backscattered power
of incoherent scatter radars up to 5 orders of magnitudes
above the thermal backscatter are sometimes observed at
high latitudes. Recently observations of enhancements in the
backscattered power including a feature at zero Doppler shift
have been reported. These enhancements are limited in altitude
to tens of kilometers. The zero Doppler shift feature has
been interpreted as a signature of electron density cavitation.
Enhanced plasma lines during these observations have also
been reported. We report on the first EISCAT UHF observations
of enhanced backscattered radar power including a zero
Doppler shift feature. The enhancements originated from two
distinct and intermittent layers at about 200 km altitude. The
altitude extent of the enhancements, observed during auroral
high-energy electron precipitation, was < 2 km. | en |
