Mesospheric studies using the Jicamarca incoherent-scatter radar
(Elsevier, 1974-07)
Results from a VHF backscattering experiment using the Jicamarca incoherent-scatter radar are described for a mesospheric height. The echo power during the day varies intermittently and sporadically over a range of almost ...
Scientific contributions of the Jicamarca Observatory peculiar to its equatorial latitude of operating frequency
(Instituto Panamericano de Geografia e Historia, 1983-01)
We shall limit ourselves here to a brief discussion of the work done at the Jicamarca Observatory connected either with: a) the geometry of the Magnetic Field or, b) with backscatter from enhanced fluctuations (non-thermal) ...
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 ...
Equatorial F region vertical plasma drifts during solar maxima
(American Geophysical Union, 1989-09-01)
Incoherent scatter radar measurements at Jicamarca are used to study the effects of large solar fluxes and magnetic activity on the F region vertical plasma drifts. The average drifts from the two last solar maxima are ...
Height variation of gaps in 150‐km echoes and whole atmosphere community climate model electron densities suggest link to upper hybrid resonance
(American Geophysical Union, 2020-01)
Radar echoes from the daytime lower F region near the magnetic equator, so-called 150-km echoes, have been puzzling researchers for decades. Neither the mechanisms that generate the enhanced backscatter at very high ...
Average vertical and zonal F region plasma drifts over Jicamarca
(American Geophysical Union, 1991-08)
The seasonal averages of the equatorial F region vertical and zonal plasma drifts are determined using extensive incoherent scatter radar observations from Jicamarca during 1968–1988. The late afternoon and nighttime ...
F-region electric field and electrojet observations during the november 3, 1994, total eclipse
(Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1994-11-03)
On November 3, 1994, a total solar eclipse occurred at about 7:10 a.m. local time, with a maximum occultation path tangent to the southern coast of Peru. Occultation was not total at Jicamarca; it was 95%. The maximum ...
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 ...
Observations of the April 2002 geomagnetic storm by the global network of incoherent scatter radars
(European Geosciences Union (EGU), 2005-01)
This paper describes the ionospheric response to a geomagnetic storm beginning on 17 April 2002. We present the measurements of ionospheric parameters in the F-region obtained by the network of eight incoherent scatter ...
Coherent and incoherent scatter radar study of the climatology and day-to-day variability of mean F-region vertical drifts and equatorial spread F
(American Geophysical Union, 2016-02)
We conducted a comprehensive analysis of the vertical drifts and equatorial spread F (ESF) measurements made by the Jicamarca incoherent scatter radar (ISR) between 1994 and 2013. The ISR measurements allowed us to construct ...
