Journal ArticleDOI
Initial observations with the Global Ultraviolet Imager (GUVI) in the NASA TIMED satellite mission
Andrew B. Christensen,Larry J. Paxton,Susan K. Avery,John D. Craven,G. Crowley,David C. Humm,Hyosub Kil,R. R. Meier,C.-I. Meng,Daniel Morrison,B. Ogorzalek,Paul R. Straus,D. J. Strickland,R. M. Swenson,Richard L. Walterscheid,Brian C. Wolven,Yongliang Zhang +16 more
TL;DR: The Global Ultraviolet Imager (GUVI) was used by the NASA TIMED satellite to measure the spectral radiance of the Earth's far ultraviolet airglow in the spectral region from 120 to 180 nm using a cross-track scanning spectrometer design as discussed by the authors.
Journal ArticleDOI
Global Distribution of Density Irregularities in the Equatorial Ionosphere
Hyosub Kil,Roderick A. Heelis +1 more
TL;DR: In this paper, the retarding potential analyzer onboard the Earth Explorer-E (AE-E) satellite was used to measure ion number density at high and low altitude using the rms deviation ΔN/N over a path length of 18 km as an indicator of overall irregularity intensity.
Journal ArticleDOI
Occurrence of equatorial F region irregularities: Evidence for tropospheric seeding
TL;DR: In this paper, a gap-free version of the seasonal and longitudinal 0 (s/l) variations of P(sub EFI), the equatorial F region irregularity (EFI) occurrence probability, based on data from the AE-E spacecraft is presented.
Journal ArticleDOI
Longitudinal structure of the vertical E × B drift and ion density seen from ROCSAT‐1
Hyosub Kil,Seung-Jun Oh,Michael C. Kelley,Larry J. Paxton,Scott L. England,Elsayed R. Talaat,Kyoung-Wook Min,S.-Y. Su +7 more
TL;DR: In this article, the longitudinal distribution of the vertical E × B drift velocity and ion density in the low-latitude ionosphere using the first Republic of China Satellite (ROCSAT-1) data acquired during 1999-2004 was investigated.
Journal ArticleDOI
O/N2 changes during 1–4 October 2002 storms: IMAGE SI‐13 and TIMED/GUVI observations
Yongliang Zhang,Larry J. Paxton,Daniel Morrison,Brian C. Wolven,Hyosub Kil,C.-I. Meng,Stephen B. Mende,Thomas J. Immel +7 more
TL;DR: In this paper, the IMAGE SI-13 and TIMED/GUVI far-ultraviolet (FUV) dayglow data, AURIC simulation results, and MSIS86 model were used to obtain the O/N2 column density ratios.
