The magnetic storms of 3_4 August 2010 and 5_6 August 2011: 1. Ground- and space-based observations
Autor: Valladares, Cesar E., Eccles, J. V., Basu, S., Schunk, Robert W., Sheehan, R., Pradipta, R., Ruohoniemi, J. M.
Publikováno v: All Physics Faculty Publications
We have used total electron content (TEC) values from low, middle, and high latitudes recorded over the American continent and density and ion temperature measured in situ by the DMSP-F15 and F17 satellites during the geomagnetic storms of 3_4 August

Characterizing the Lower Ionosphere with a Space - Weather - Aware Receiver Matrix
Autor: Rice, D. D., Hunsucker, R. D., Eccles, J. V., Sojka, Jan Josef, Raitt, J. W., Brady, J. J.
Publikováno v: All Physics Faculty Publications
Current ionospheric models are very good at specifying regular diurnal and seasonal variations of the E and F regions of the ionosphere. Less is known about the behavior of the D region, although progress has recently been made with models such as th

A Frequency Agile, Distributed Sensor System to Address Space Weather Effects Upon Ionospherically Dependent Systems
Autor: Rice, D. D., Eccles, J. V., Sojka, Jan Josef, Raitt, J. W., Brady, J., Hunsucker, R. D.
Publikováno v: All Physics Faculty Publications
The outstanding problem faced by operational systems that utilize the ionosphere is that ionospheric weather variability is comparable to the ionospheric climate variability. However, the number of simultaneous measurements is orders of magnitude too

Space Weather Effects on Mid-Latitude HF Propagation Paths: Observations and a Data-Driven D-Region Model
Autor: Eccles, J. V., Hunsucker, R. D., Rice, D., Sojka, Jan Josef
Publikováno v: All Physics Faculty Publications
A two-pronged study is under way to improve understanding of the D region response to space weather and its effects on HF propagation. One part, the HF Investigation of D region Ionospheric Variation Experiment (HIDIVE), is designed to obtain simulta

Ionospheric Assimilation Techniques for ARGOS Low-Resolution Airglow and Aurora Spectrograph (LORAAS) Tomographically Reconstructed Equatorial Electron Density Profiles
Autor: Sojka, J. J., Eccles, J. V., Schunk, R. W., Mcdonald, S., Thonnard, S., Kenneth Dymond, Mccoy, R. P.
Publikováno v: All Physics Faculty Publications
Scopus-Elsevier
The LORAAS instrument aboard the ARGOS satellite observes line-of-sight ultraviolet limb intensities from ionosphere and thermosphere airglow. This study uses tomographically reconstructed electron density profiles (EDPs) from the nightside emissions

Understanding Mid-Latitude Space Weather: Storm Impacts Observed at BLO on 31 March 2001
Autor: Sojka, Jan Josef, Rice, D., Eccles, J. V., Berkey, F. T., Kintner, P., Denig, W.
Publikováno v: All Physics Faculty Publications
On 30 March 2001 in the late evening an auroral display was observed over the United States of America. The Bear Lake Observatory (BLO) magnetometer in Utah measured changes of 550 nT in less than 30 min. During the same period, BLO ionosonde measure
