TL;DR: The spread F Experiment (or SpreadFEx) as discussed by the authors performed an extensive experimental campaign from September to November 2005 to define the role of neutral atmosphere dynamics, specifically wave motions propagating upward from the lower atmosphere, in seeding equatorial spread F and plasma bubbles extending to higher altitudes.

Sharon L. Vadas,Geoff Crowley +1 more
TL;DR: In this paper, the authors study the 10 traveling ionospheric disturbances (TIDs) observed at zobs∼283 km by the TIDDBIT ionosphere sounder on 30 October 2007 at 0400-0700 UT near Wallops Island, USA.

Characteristics of sprite and gravity wave convective sources present in satellite IR images during the SpreadFEx 2005 in Brazil
F. T. São Sabbas,V. T. Rampinelli,J. Santiago,P. Stamus,Sharon L. Vadas,David C. Fritts,Michael J. Taylor,Pierre-Dominique Pautet,G. Dolif Neto,Osmar Pinto +9 more
TL;DR: In this article, the authors used GOES IR images of South America on the night of 30 September to 1 Octo- ber and 25-26 October 2005, as part of the Spread F Experiment (SpreadFEx) in Brazil in 2005, to identify and evaluate the size, intensity and Tropopause overshoot of thun- derstorm convective cores expected to be significant sources of gravity waves.
Journal ArticleDOI
Forward ray-tracing for medium-scale gravity waves observed during the COPEX campaign
Igo Paulino,H. Takahashi,Sharon L. Vadas,Cristiano Max Wrasse,J. H. A. Sobral,Amauri Fragoso de Medeiros,Ricardo Buriti,Delano Gobbi +7 more
TL;DR: In this paper, medium-scale gravity waves (MSGWs) observed during the Conjugate Point Experiment (COPEX) at Boa Vista (2.8°N; 60.7°S, dip angle 21.6°S) have been ray-traced and studied based on zero wind and model wind conditions.

Seasonal Propagation Characteristics of MSTIDs Observed at High Latitudes Over Central Alaska Using the Poker Flat Incoherent Scatter Radar
Michael Negale,Michael J. Taylor,Michael Nicolls,Sharon L. Vadas,Kim Nielsen,Craig Heinselman +5 more
TL;DR: In this article, near-continuous electron density measurements obtained over a ∼3 year period, 2010-2013, using the Poker Flat Incoherent Scatter Radar (PFISR) in central Alaska (69∘N, 147∘W) have been analyzed to quantify the properties of over 650 high-latitude medium-scale traveling ionospheric disturbances (MSTIDs).
