ID-264 :   Imaging Riometer Experiment at Poker Flat, Alaska



Research/Observation Title

Imaging Riometer Experiment at Poker Flat, Alaska

Science Summary (common)

[purpose] For studying lower ionospheric disturbances and particle precipitation over Poker Flat, Alaska [outline] The Poker Flat imaging riometer installed in October, 1995, has the greatest number of antenna elements and beam patterns in the world at present (July 2005), and mainly observes the cosmic noise absorption (CNA) caused by the enhancement of electron density in the ionospheric D region. This imaging riometer obtains two-dimensional images of the CNA in the region of 400km x 400km square with the 11km spatial and 1sec temporal resolutions.
