Multi-instrumented observations of the equatorial F-region during June solstice: large-scale wave structures and spread-F
(SpringerOpen, 2018-03)
Typical equatorial spread-F events are often said to occur during post-sunset, equinox conditions in most longitude sectors. Recent studies, however, have found an unexpected high occurrence of ionospheric F-region ...
Radar and satellite global equatorial F region vertical drift model
(American Geophysical Union, 1999-04-01)
We present the first global empirical model for the quiet time F region equatorial vertical drifts based on combined incoherent scatter radar observations at Jicamarca and Ion Drift Meter observations on board the Atmospheric ...
Quiet time equatorial F region vertical plasma drift model derived from ROCSAT‐1 observations
(American Geophysical Union, 2008-05-03)
We have used five years of measurements on board the ROCSAT‐1 satellite to develop a detailed quiet time global empirical model for equatorial F region vertical plasma drifts. This model describes the local time, seasonal ...

Radar Observations of Equatorial Ionospheric Irregularities
(International Science Congress Association, 2015-10-24)
Long-term data set of radar observations using coherent and incoherent scatter radar sources during 1996-2008 were used to study the trend of low-latitude ionospheric irregularities, also referred to as equatorial spread ...
A comparison of ground and satellite observations of F region vertical velocity near the dip equator
(American Geophysical Union, 2008-01-12)
Nighttime F region vertical electrodynamic drifts were made at the magnetic equatorial stations in Africa, Ibadan (7.4°N, 3.9°E; 6°S dip), and Ouagadougou (12°N, 1.5°W; 5.9°N dip) using ionosondes hmF2 data during 1957/1958 ...
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 ...
On the Genesis of Postmidnight Equatorial Spread F: Results for the American/Peruvian Sector
(American Geophysical Union, 2018-07-16)
Previous studies of the Earth's low‐latitude ionosphere using in situ measurements made by sensors on the Communication/Navigation Outage Forecasting System (C/NOFS) satellite showed an unexpected predominance of equatorial ...
