Record #146877:

A high-latitude observation of sporadic sodium and sporadic E- layer formation / C.J. Heinselman, J.P. Thayer.

Title: A high-latitude observation of sporadic sodium and sporadic E- layer formation / C.J. Heinselman, J.P. Thayer.
Author(s): Heinselman, C. J.
Thayer, J. P.
Date: 1998.
In: Geophysical Research Letters. (1998.), Vol. 25(16) (1998)
Abstract: High-resolution radar and lidar measurements of sporadic sodium and sporadic E layers were made at Sondrestrom incoherent-scatter radar facility on 11 December 1997. Measurements suggested causal link between layers, supporting proposed mechanism in which Na⁺ ions in E, are neutralised to form Na,. This Na, does not seem to have been formed in presence of auroral precipitation or ionisation; sodium density decreases during aurora.
