We discuss the use of the 450-MHz Poker Flat Incoherent Scatter Radar (PFISR) for incoherent-scatter (IS) based D-region observations, which have been undertaken since the summer of 2007. Monthly observations indicate periods of enhanced and detectable D-region IS returns, often but not always associated with energetic auroral precipitation. The nature of these active versus quiet periods are investigated. Routine observations consist of electron densities, spectral widths, and line-of-sight speeds at altitudes ranging from 60-90 km. In addition, using the pulse-to-pulse beam steering capabilities of PFISR, horizontal and vertical motions (full vector winds) are routinely resolved at high temporal (few minute) and range (0.6-1.5 km) resolution. We present evidence for gravity wave motions (medium/high frequency as well as inertial) and mean winds, from which wavelengths and intrinsic frequencies are derived.
