The modeling methods used in the study were artificial neural network (ANN), linear regression (LR) and polynomial functions. The approach taken was to first test the modeling techniques on a single station before expanding the study to cover the regional aspect. The single station modeling was developed based on ionosonde data over Grahamstown. The inputs for the model which related to seasonal variation, diurnal variation, geomagnetic activity and solar activity were considered. For the geomagnetic activity, three indices namely; the symmetric disturbance in the horizontal component of the Earth’s magnetic field (SYM − H), the Auroral Electrojet (AE) index and local geomagnetic index A, were included as inputs. The performance of a single station model revealed that, of the three geomagnetic indices, SYM − H index has the largest contribution of 41% and 54% based on ANN and LR techniques respectively. The average correlation coefficients (R) for both ANN and LR models was 0.8, when validated during the selected storms falling within the period of model development. When validated using storms that fall outside the period of model development, the model gave R values of 0.6 and 0.5 for ANN and LR respectively. In addition, the GPS total electron content (TEC) derived measurements were used to estimate foF2 data. This is because there are more GPS receivers than ionosonde locations and the utilisation of this data increases the spatial coverage of the regional model. The estimation of foF2 from GPS TEC was done at GPS-ionosonde co-locations using polynomial functions. The average R values of 0.69 and 0.65 were obtained between actual and derived _foF2 over the co-locations and other GPS stations respectively. Validation of GPS TEC derived foF2 with RO data over regions out of ionospheric pierce points coverage with respect to ionosonde locations gave R greater than 0.9 for the selected storm period of 4-8 August 2011. The regional storm-time model was then developed based on the ANN technique using the four South African ionosonde stations. The maximum and minimum R values of 0.6 and 0.5 were obtained over ionosonde and GPS locations respectively. This model forms the basis towards the regional ionospheric storm-time index.]]> Mon 31 May 2021 15:12:57 SAST ]]> A systematic review on the use of methylphenidate as a performance-enhancing substance in tertiary institutions https://commons.ru.ac.za/vital/access/manager/Repository/vital:43269 Mon 21 Jun 2021 10:30:43 SAST ]]> An appraisal of selected support services rendered by social workers to older persons in De Aar service area, Northern Cape Province https://commons.ru.ac.za/vital/access/manager/Repository/vital:46925 Mon 21 Feb 2022 11:24:46 SAST ]]> Photodynamic antimicrobial chemotherapy against Staphylococcus aureus and Escherichia coli sensitized using indium (III) cationic porphyrins linked to core-shell magnetic nanoparticles https://commons.ru.ac.za/vital/access/manager/Repository/vital:42801 Mon 17 May 2021 15:20:31 SAST ]]> Night-time gravity waves detected with multi-frequency airglow imager https://commons.ru.ac.za/vital/access/manager/Repository/vital:42931 Mon 17 May 2021 13:00:31 SAST ]]> The state and civil society in building a capable developmental state : a case of the National Department of Social Development and the Non Profit Organisations sector in South Africa https://commons.ru.ac.za/vital/access/manager/Repository/vital:48824 Fri 25 Mar 2022 12:03:44 SAST ]]> Perceptions and attitudes towards leadership styles and staff morale in Eastern Cape Provincial Treasury https://commons.ru.ac.za/vital/access/manager/Repository/vital:42398 Fri 20 Jan 2023 13:57:22 SAST ]]> Rural enterprise development as a means to poverty alleviation https://commons.ru.ac.za/vital/access/manager/Repository/vital:41797 Fri 20 Jan 2023 10:36:04 SAST ]]> Taxonomic, ecological and biogeographic re-evaluation of temperate stream fishes in Southern Africa: a case study of the enteromius anoplus complex https://commons.ru.ac.za/vital/access/manager/Repository/vital:45051 Fri 18 Feb 2022 11:43:00 SAST ]]> Social policy and regional integration in SADC: a regional health care perspective https://commons.ru.ac.za/vital/access/manager/Repository/vital:43386 Fri 09 Jul 2021 10:59:21 SAST ]]> Colonial power and the transformation of feudal relations in Buganda 1900-1962 https://commons.ru.ac.za/vital/access/manager/Repository/vital:49670 Fri 08 Apr 2022 10:39:49 SAST ]]>
