Comparisons of full correlation analysis (FCA) and imaging Doppler interferometry (IDI) winds using the Buckland Park MF radar

Autor: D. A. Holdsworth, I. M. Reid

Publikováno v: Annales Geophysicae, Vol 22, Pp 3829-3842 (2004)

We present results from three years of mesospheric and thermospheric wind measurements obtained using full correlation analysis (FCA) and imaging Doppler interferometry (IDI) for the Buckland Park MF radar. The IDI winds show excellent agreement w
