Poker Flat Radar data archived



An archive of Poker Flat Mesosphere, Stratosphere and Troposphere (MST) radar observations has recently been completed by the National Oceanic and Atmospheric Administration Aeronomy Laboratory in Boulder, Colo. The Poker Flat MST radar was one of the first wind-profiling Doppler radars. Construction began in 1978 near Fairbanks, Alaska, with the support of the National Science Foundation, and the radar was in routine operation from early 1979–1985.

The archive includes observations of vertical and horizontal velocities, Doppler spectral width of horizontal and vertical motions, and signal strength. The observations are essentially continuous in time and cover an altitude range of about 5–30 km and 55–95 km, depending on season and time of day. In preparing the archive, data were carefully checked for consistency, and a special effort was made to optimize the retrieval of data from altitudes with low signal-to-noise ratio.
