Ionospheric scintillation impact on ambiguity resolution using ADOP in closed form
(2019-08-15)
The Ambiguity Dilution of Precision (ADOP) is a well-known scalar measure that can be used to infer the strength of the Global Navigation Satellite System (GNSS) model of the carrier phase ambiguities involved in precise ...
Penetration characteristics of the interplanetary electric field to the daytime equatorial ionosphere
(American Geophysical Union, 2008-12-23)
Using 8 years of ionospheric drift measurements from the low‐latitude JULIA (Jicamarca Unattended Long‐term Investigations of the Ionosphere and Atmosphere) radar and the solar wind and interplanetary magnetic field data ...
Ionospheric Specification and Space Weather Forecasting With an HF Beacon Network in the Peruvian Sector
(American Geophysical Union, 2018-08-14)
A network of high‐frequency (HF) transmitters and receivers used for ionospheric specification is being installed in Peru. The HF transmitters employ multiple frequencies and binary phase coding with pseudorandom noise, ...
Moderate geomagnetic storms and their ionospheric effects at middle and low latitudes
(Elsevier, 2011-08)
This paper reports the global response of the mid high and low latitude ionosphere in four longitudinal sectors to two moderate geomagnetic storms that occurred during 2007 (the more intense storms occurred that year). The ...
Climatology of F region zonal plasma drifts over Jicamarca
(American Geophysical Union, 2005-12)
We use extensive incoherent scatter radar observations made at the Jicamarca Radio Observatory between 1970 and 2003 to study and model empirically the equatorial zonal plasma drifts near the F region peak using Bernstein ...
Superposed epoch analysis of the dayside ionospheric response to four intense geomagnetic storms
(American Geophysical Union, 2008-07-09)
Prompt daytime ionospheric responses are presented for the following four intense geomagnetic storms: 29 October 2003, 30 October 2003, 20 November 2003, and 7 November 2004. We perform a superposed epoch analysis of the ...
Radio beacon and radar assessment and forecasting of equatorial F region ionospheric stability
(American Geophysical Union, 2019-11)
Ionospheric conditions on two adjacent nights in March 2019 were observed at the Jicamarca Radio Observatory using a combination of incoherent scatter, coherent scatter, and high‐frequency (HF) radio modes. The HF data ...
A multistatic HF beacon network for ionospheric specification in the Peruvian sector
(American Geophysical Union, 2016-05-04)
A small network of HF beacon transmitters and receivers has been deployed in Peru for specifying the F region ionosphere in the sector. The effort is motivated by ionospheric disturbances associated with equatorial spread ...
Flux tube analysis of L‐band ionospheric scintillation
(American Geophysical Union, 2013-04-23)
This manuscript presents magnetic flux tube analysis of L‐band signal scintillation in the nighttime equatorial and low‐latitude ionosphere. Residues of the scintillation index urn:x wiley:jgra:media:jgra50285:jgra50285-math-0001 ...
