Assessment of global ionospheric maps performance by means of ionosonde data
(2020-10-02)
This work presents a new method for assessing global ionospheric maps (GIM) using ionosonde data. The method is based on the critical frequency at the F2 layer directly measured by ionosondes to validate VTEC (vertical ...
COMPARISON OF GNSS INDICES, IONOSONDES AND ALL-SKY IMAGERS IN MONITORING THE IONOSPHERE IN BRAZIL DURING QUIET AND DISTURBED DAYS
(Univ Federal Parana, Centro Politecnico, 2019-01-01)
Measurements from the Global Navigation Satellite System (GNSS) have become a leading data source for ionospheric studies. Different technologies are used to monitor the ionospheric layer. It is possible to carry out this ...
The use of ionosondes in GPS ionospheric tomography at low latitudes
(American Geophysical Union, 2012-10-25)
A new technique is presented for the incorporation of ionosonde observations into GPS ionospheric tomography. This approach greatly improves the vertical resolution of the images when using independent incoherent scatter ...
Ionosonde observations of ionospheric disturbances due to the 15 February 2013 Chelyabinsk meteor explosion
(American Geophysical Union, 2015-10-29)
We report the results of our investigations on the potential ionospheric effects caused by the 15 February 2013 Chelyabinsk meteor explosion. We used the data from a number of digisonde stations located in Europe and Russia ...
Comparison of ionosonde and incoherent scatter drift measurements at the magnetic equator
(American Geophysical Union, 2006-01-10)
It has been proposed that ionosondes can be used to measure vectorial nighttime ionospheric drifts at F region altitudes. These measurements have been validated at mid and high magnetic latitudes on campaign basis. Here ...
The LISN database: description and initial results
(Instituto Geofísico del Perú, 2009)
The heavy volume of data that GPS, ionosondes and magnetometers are continuously collecting is stored in the LISN server and managed using a set of rules that are intended to provide an efficiently way to manipulate the ...
Doppler measurements with a digital ionosonde: Technique and comparison of results with incoherent scatter data
(American Geophysical Union, 1982-09)
A simple technique for measuring the amplitude and Doppler shift of vertically reflected HF echoes has been implemented for the Arecibo digital ionosonde. This technique can easily be adapted to other digital ionosondes ...
Study of waves observed in the equatorial ionospheric valley region using Jicamarca ISR and VIPIR ionosonde
(University of Illinois at Urbana-Champaign, 2017)
Incoherent scatter (IS) radar and ionosonde (VIPIR, vertical incidence pulsed ionospheric radar) data were taken concurrently at Jicamarca during campaigns of January, April, June, and July 2015, January 2016, and most ...
LISN activities at Jicamarca 2009-2010
(Instituto Geofísico del Perú, 2010)
Diapositivas presentadas en el 2010 CEDAR Workshop, University of Colorado, Boulder, CO, 20-25 June 2010.
Comparison between nighttime ionosonde, incoherent scatter radar, AE‐E satellite, and HF Doppler observations of F region vertical electrodynamic plasma drifts in the vicinity of the magnetic equator
(American Geophysical Union, 2006-11-23)
Nighttime F region vertical drifts were made using an ionosonde for the equatorial station Ibadan (7.4°N, 3.9°E, 6°S dip) from 1 year of data during 1957–1958 International Geophysical Year (IGY) that corresponds to a ...
