Analysis of ionospheric scintillation spectra and TEC in the Chinese low latitude region
GPS L-band scintillations and total electron content (TEC) were recorded at Sanya (18.33◦N, 109.52◦E) during the period July 2004–July 2005. Automatic recorded raw digital scintillation data are analyzed to obtain the spectral characteristics of irregularities producing ionospheric scintillations and to estimate the correlation between amplitude scintillation and power spectral density. Concurr...
متن کاملSimultaneous VHF radar backscatter and ionosonde observations of low-latitude E region
The first results of simultaneous observations made on the low-latitude field-aligned irregularities (FAI) using the MST radar located at Gadanki (13.5 N, 79.2 E, dip 12.5) and the Es parameters using an ionosonde at a nearby station Sriharikota (13.7 N, 80.1 E, dip 12.6) are presented. The observations show that while the height of the most intense radar echoes is below the virtual height of E...
متن کاملCOMPARISON OF A LOW-LATITUDE IONOSPHERIC MODEL WITH OBSERVATIONS OF 01 630 nm EMISSION AND IONOSPHERIC PARAMETERS
A comparative study is carried out between a semi-empirical low-latitude ionospheric model (SLIM). including calculated 01 630 nm airglow emission intensities predicted by the SLIM model, with ionospheric and r>I 630 nm airglow measurements carried out at Cachoeira Paulista (22.7”S, 45.O”W; geomag. 11.9”S), Brazil. A long series of regular measurements of ionospheric F-region peak electron dens...
متن کاملIonospheric redistribution during geomagnetic storms
[1]The abundance of plasma in the daytime ionosphere is often seen to grow greatly during geomagnetic storms. Recent reports suggest that the magnitude of the plasma density enhancement depends on the UT of storm onset. This possibility is investigated over a 7year period using global maps of ionospheric total electron content (TEC) produced at the Jet Propulsion Laboratory. The analysis confir...
متن کاملIonospheric Estimation using Extended Kriging for a low latitude SBAS
The ionosphere causes the most difficult error to mitigate in Satellite Based Augmentation Systems (SBAS). The problem has been solved for the mid latitude regions using the thin shell approximation. There, it is very accurate on quiet days and allows the augmentation system so send the information in a two dimensional grid with a five by five degree resolution. However, even during quiet days,...
