High-Altitude V/UHF Radar Meteor Observations

Recent observations at the Jicamarca Radio Observatory (JRO) designed to study fragmentation surprisingly point unambiguously to radar meteors at altitudes of up to ~ km. This result will likely prove controversial and, as 180 such, requires additional observations especially designed toward understand the radio science of these meteors. That is, we must understand the scattering mechanism before we can begin to interpret the meteoroid processes involved in creating the necessary plasma. In particular, we have not, to date, noticed these high-altitude events in the Arecibo VHF observations. Is this because we were not explicitly looking for these events and/or is the JRO ~ k-perp-B geometry critical to the detectability of scattering?To this end we request a minimum of two 8-hour"'0000 - 0800 AST"'observation sets using both the AO U/VHF radars.
