Physics‐based forecasts of equatorial radio scintillation for the Communication and Navigation Outage Forecasting System (C/NOFS)
(American Geophysical Union, 2005-12-28)
The plans for producing long‐term (6–24 hour) forecasts of equatorial plasma structure and radio scintillation for the Communication and Navigation Outage Forecasting System (C/NOFS) program are described. We discuss the ...
Forecasting the occurrence of ionospheric scintillation activity in the equatorial ionosphere on a day-to-day basis
(Elsevier, 2004-11)
In the low-latitude ionospheric F region, ambient conditions after sunset are often conducive to the generation of small-scale plasma density structures by the Rayleigh–Taylor instability mechanism. Radio wave signals ...
Equatorial scintillation and systems support
(American Geophysical Union, 1997-09)
The need to nowcast and forecast scintillation for the support of operational systems has been recently identified by the interagency National Space Weather Program. This issue is addressed in the present paper in the ...
Tackling ionospheric scintillation threat to GNSS in Latin America
(Edp Sciences S A, 2011-01-01)
Scintillations are rapid fluctuations in the phase and amplitude of transionospheric radio signals which are caused by small-scale plasma density irregularities in the ionosphere. In the case of the Global Navigation ...
Kriging method to perform scintillation maps based on measurement and GISM model
(American Geophysical Union, 2014-08-27)
This paper presents an ionosphere scintillation mapping algorithm. The technique used is a Kriging technique, well known in geostatistics. It is an interpolation method applied to a set of random data, namely, in this ...
C/NOFS: a mission to forecast scintillations
(Elsevier, 2004-09-13)
This article describes the science to be pursued during the Communication/Navigation Outage Forecasting System (C/NOFS) Mission of the Air Force Research Laboratory. The primary purpose of C/NOFS is to forecast the presence ...
Exploring the correlation between ionospheric scintillation and GNSS positioning error near the magnetic equator using machine learning techniques
(Instituto Geofísico del Perú, 2020-06)
Ionospheric scintillations are a common phenomenon in the equatorial ionosphere. This phenomenon directly affects the position estimated by GNSS receivers degrading the quality of the radio signals; however, the quantification ...
Tackling ionospheric scintillation threat to GNSS in Latin America
(Edp Sciences S A, 2015)
A measure of ionospheric irregularities: zonal velocity and its implications for L-band scintillation at low-latitudes
(2021-09-01)
We estimate the zonal drift velocity of small-scale ionospheric irregularities at low latitude by leveraging the spaced-receivers technique applied to two GNSS receivers for scintillation monitoring installed along the ...
Modeling the low-latitude ionospheric electron density and plasma turbulence in the November 2004 storm period
(Elsevier, 2010-03)
The storm period of 8–12 November 2004 offers an opportunity for insight into the phenomena of low-latitude ionospheric structure during geomagnetically disturbed times because of the strength of the disturbances, the ...
