(1) CEDAR-GEM individual workshops, 26 June-01 July 2011, Santa Fe, NM, http://cedarweb.hao.ucar.edu/wiki/index.php/2011_Workshop:Main.
- (a)CEDAR workshop "Theoretical and experimental studies of the low-latitude thermosphere-ionosphere system" on Tues 28 Jun.
From Fabiano Rodrigues (frodrigues at astraspace.net).
Conveners: Odile de La Beajuardiere, Gang Lu, Jonathan Makela and Fabiano Rodrigues
In the past few years, new hypotheses and theories describing equatorial spread F initiation and development have been proposed. New and exciting ground-based and in-situ observations of the Ionosphere-Thermosphere (IT) at low-latitudes have also been made. Additionally, numerical modeling capabilities of the low-latitude IT have significantly improved. This workshop will provide an opportunity for the CEDAR community to present and discuss results of theoretical and experimental studies related to the low-latitude IT system; emphasizing equatorial spread F (ESF).
The workshop welcomes contributions on experimental investigations, theoretical analyses and numerical simulation studies, including assimilative models of the low-latitude ionosphere, and non-linear models of ESF. The presentation of results related to observations of the low-latitude IT or phenomena related to ESF, especially those made by new ground stations, by C/NOFS and results from the spreadFEx2 campaign in Brazil are expected. Additionally, we anticipate contributions related to studies of the effects of magnetosphere-ionosphere coupling processes on the low-latitude thermosphere/ionosphere and ESF as well as on the effects caused by the coupling with the lower and neutral atmosphere.
