abstract. Dartmouth College led the build of two additional radars with 24 beams near Christmas Valley, Oregon in November as part of the collaboration to develop a network of mid-latitude radars. Recent research on near-range backscattering drifts, has focused on how to determine the classification of meteors trail echoes from other backscattering, such as E-region irregularities and background noise, using the mid-latitude radars. With two radars in close proximity, a comparison on derived velocities show different results that may be caused from E-region plasma drifts that have similar characteristics of meteor trail echoes. A clear distinguish on classifying meteor trail echoes will be a useful tool to develop a global analysis of neutral winds with multiple SuperDARN radars around the mid-latitude region.
