Assimilation of Multiple Data Types to a Regional Ionosphere Model With a 3D-Var Algorithm (IDA4D) For the purpose of building a regional (bound 20\textendash60\textdegreeN in latitude and 110\textendash160\textdegreeE in longitude) ionospheric nowcast model, we investigated the performance of IDA4D (Ionospheric Data Assimilation Four-Dimension) technique considering International Reference Ionosphere model as the background. The data utilized in assimilation were slant total electron content (STEC) from 27 ground GPS (Global Positioning System) receiver stations and NmF2 (ionospheric F2 peak density) from five ionoson ...

Dayside and nightside segments of a polar arc: The particle characteristics Park, J.; Min, K.; Parks, G.; Zhang, Y.; Lee, J.-J.; Baker, J.; Kim, H.; Hwang, J.; Yumoto, K.; Uozumi, T.; Lee, C.; Published by: Journal of Geophysical Research Published on: Jan-01-2012 YEAR: 2012   DOI: 10.1029/2011JA017323 |
A steep plasma density gradient has been observed in the middle-latitude F region during large geomagnetic storms. This phenomenon can be understood as a special form of the middle-latitude ionization trough (hereafter trough), but its causal linkage has not yet been clarified. We investigate the association of the steep density gradient and the trough by comparing their morphologies and occurrence locations using the satellite and ground observation data during the 11\textendash12 April 2001 storm. Steep density ... Park, S.; Kim, K.-H.; Kil, H.; Jee, G.; Lee, D.-H.; Goldstein, J.; Published by: Journal of Geophysical Research Published on: 05/2012 YEAR: 2012   DOI: 10.1029/2011JA017349 |
