First Rocket Campaign at Poker Flat

First Rocket Campaign at Poker Flat

Poker Flat AMISR operated 105 hours over 18 nights in support of JOULE II and ROPA rockets in January and February. At right, a TMA trail released by 1 of 4 JOULE II rockets in the early morning of 19 January. Real-time AMISR data show the strong auroral precipitation and large eastward ion flow that met launch criteria. 

TOP: Long pulse electron density vs. altitude and time from seven simultaneous AMISR beams; look angles given above each plot. BOTTOM: ion velocity vs. time and latitude for two hours around launch.

First AMISR Planning Meeting

First AMISR Planning Meeting

The First AMISR Science Planning Workshop was held October 11–13, 2006 at Asilomar Conference Grounds in Pacific Grove, California, to discuss science plans for the Advanced Modular Incoherent Scatter Radar. The goal of the workshop was to explore the range of science objectives that can be achieved with this new NSF facility at the two high-latitude locations, Poker Flat, Alaska, and Resolute Bay, Nunavut, Canada. Of particular interest was the coordination of future AMISR observations with that of other instrumentation, such as optical measurements, magnetometer data, and GPS TEC data.
