A study on the response of the equatorial ionization anomaly over the east Africa sector during the geomagnetic storm of November 13, 2012
(University of Nairobi, 2015-06)
Using a set of up to 12 International GNSS Services (IGS) receivers around the East African region, we present the formation of the peak of ionospheric Equatorial Ionization Anomaly during the geomagnetic storm of 13th ...
Characterization of ionospheric GPS Total Electron Content (GPS-TEC) in low latitude zone over the Kenyan region during a very low solar activity phase
(University of Nairobi, 2012)
The ionosphere Total Electron Content (TEC), derived by analyzing dual frequency signals from the Global Positioning System (GPS) recorded from two stations in the Kenyan region is studied. We present the mean diurnal, ...
Annual and semi-annual Sq variations at 96° MM MAGDAS I and II stations in Africa
(University of Nairobi, 2012)
The quiet daily variations of the geomagnetic field (Sq) have been studied by using the geomagnetic data of the 10 International Quietest Days. Geomagnetic data from MAGDAS I and II stations-ten stations were selected ...
Using GPS-SCINDA observations to study the correlation between scintillation, total electron content enhancement and depletions over the Kenyan region
(University of Nairobi, 2012-05)
This paper presents the first results of total electron content (TEC) depletions and enhancement associated with ionospheric irregularities in the low latitude region over Kenya. At the low latitude ionosphere the diurnal ...
Low Latitude Ionospheric Scintillation And Zonal Irregularity Drifts Observed With GPS-SCINDA System And Closely Spaced VHF Receivers In Kenya
(University of Nairobi, 2013-05)
In this study we have used VHF and GPS-SCINDA receivers located at Nairobi (36.8°E, 1.3°S, dip −24.1°) in Kenya, to investigate the ionospheric scintillation and zonal drift irregularities of a few hundred meter-scale ...
Near Real-time Tropospheric Water Vapour Profiling Using A Ground-based GPS Receiver
(University of Nairobi, 2017)
This article presents a remote-sensing tool employing an artificial neural networks algorithm for near real-time determination of the relative humidity (RH) profile above a site using global positioning system (GPS) data ...
