TL;DR: The SPEDAS development history, goals, and current implementation are reviewed, and its “modes of use” are explained with examples geared for users and its technical implementation and requirements with software developers in mind are outlined.

Identifying the Driver of Pulsating Aurora
Yukitoshi Nishimura,Yukitoshi Nishimura,Jacob Bortnik,Wen Li,Richard M. Thorne,Larry R. Lyons,Vassilis Angelopoulos,Vassilis Angelopoulos,Vassilis Angelopoulos,Stephen B. Mende,John W. Bonnell,O. Le Contel,Christopher Cully,Robert E. Ergun,Uli Auster +14 more
TL;DR: Direct evidence is provided that a naturally occurring electromagnetic wave, lower-band chorus, can drive pulsating aurora, and the findings can be used to constrain magnetic field models with much higher accuracy than has previously been possible.
Journal ArticleDOI
Substorm triggering by new plasma intrusion: THEMIS all‐sky imager observations
Yukitoshi Nishimura,Yukitoshi Nishimura,Larry R. Lyons,Shasha Zou,Shasha Zou,Vassilis Angelopoulos,Stephen B. Mende +6 more
TL;DR: In this article, an event and statistical analysis of THEMIS all-sky imager data was performed to identify the sequence of events leading to substorm auroral onset, and the results indicated that onset is preceded by enhanced earthward plasma flows associated with enhanced reconnection near the pre-existing open-closed field line boundary.
Journal ArticleDOI
Statistical properties of plasmaspheric hiss derived from Van Allen Probes data and their Effects on radiation belt electron dynamics
Wen Li,Qianli Ma,Richard M. Thorne,Jacob Bortnik,Craig Kletzing,William S. Kurth,George Hospodarsky,Yukitoshi Nishimura +7 more
TL;DR: Li et al. as mentioned in this paper evaluated the global distribution of the hiss wave frequency spectrum and wave intensity for different levels of substorm activity and found that observed hiss peak frequencies are generally lower than the commonly adopted value (~550Hz), which was in frequent use.
Journal ArticleDOI
THEMIS analysis of observed equatorial electron distributions responsible for the chorus excitation
Wen Li,Richard M. Thorne,Yukitoshi Nishimura,Yukitoshi Nishimura,Jacob Bortnik,Vassilis Angelopoulos,J. P. McFadden,Davin Larson,John W. Bonnell,O. Le Contel,Aurélien Roux,Uli Auster +11 more
TL;DR: Li et al. as discussed by the authors performed a statistical survey of plasma densities and electron distributions (0.5 −100 keV) using data obtained from the Time History of Events and Macroscale Interactions During Substorms spacecraft in nearequatorial orbits from 1 July 2007 to 1 May 2009 in order to investigate optimum conditions for whistler mode chorus excitation.
