Middle Atmospheric Wind Measurements Using a Medium Frequency Radar.

摘要: Abstract : The Imaging Middle-Atmospheric Geophysical Radar was located at the Boot Lake, Colorado, field site and operated 2.66 megahertz to collect radar data. data presented here were collected from 2120 Universal Time 2310 on March 20, 1983. It as a Doppler interferometer measure winds in middle atmosphere (16.5 - 91.5 kilometers), which includes stratosphere mesosphere. Highly specular returns obtained lower regions of atmosphere, with specularity increasing altitude decreased. Algorithms wee developed take these derive useful wind speeds directions region 30 55 kilometers, had not previously yielded such information easily. Three-dimensional vectors derived, values agreed well direction, but overstated magnitude when compared rawinsonde 16.5 kilometers region. taken Denver, time periods before after run.
