Studies of the thermosphere,ionosphere and plasmasphere using wavelet analysis neural networks, and kalman filters
(University of Colorado, 2009)
This thesis presents a series of studies investigating the Earth's thermosphere, ionosphere, and plasmasphere using continuous wavelet analysis techniques, multi-layer feedforward neural networks, and Kalman filters, along ...
High‐altitude incoherent‐scatter measurements at Jicamarca
(American Geophysical Union, 2017-01-31)
In an attempt to reproduce experimental results obtained in the early days of operations, electron density profiles have been measured at the Jicamarca Radio Observatory at altitudes reaching L=2. The methodology involves ...
Sources of variability in equatorial topside ionospheric and plasmaspheric temperatures
(Elsevier, 2013-01-17)
Jicamarca measurements of electron temperatures at high altitudes (500–1500 km) from the last solar minimum routinely show variations of hundreds of Kelvin from day-to-day. Possible sources of these variations are explored ...

The case for combining a large low-band very high frequency transmitter with multiple receiving arrays for geospace research: a geospace radar
(American Geophysical Union, 2019-07-09)
We argue that combining a high-power, large-aperture radar transmitter with several large-aperture receiving arrays to make a geospace radar—a radar capable of probing near-Earth space from the upper troposphere through ...
A new source of the midlatitude ionospheric peak density structure revealed by a new Ionosphere‐Plasmasphere model
(American Geophysical Union, 2016-02-02)
The newly developed Ionosphere‐Plasmasphere (IP) model has revealed neutral winds as a primary source of the “third‐peak” density structure in the daytime global ionosphere that has been observed by the low‐latitude ...
High altitude echoes from the equatorial topside ionosphere during solar minimum
(American Geophysical Union, 2021-02)
We describe a new class of nonthermal plasma density irregularities observed in the postmidnight topside equatorial ionosphere under low solar flux conditions. They are distinct from irregularities associated with equatorial ...
Storm‐enhanced plasma density and polar tongue of ionization development during the 15 May 2005 superstorm
(American Geophysical Union, 2015-05-20)
We investigate the ionosphere's global response to the 15 May 2005 superstorm in terms of storm evolution and ionospheric electrodynamics. Our aim is to study the global distribution of plasma and the resultant large‐scale ...
NeQuick 2 and IRI Plas VTEC predictions for low latitude and South American sector
(Elsevier, 2018-04)
Using vertical total electron content (VTEC) measurements obtained from GPS satellite signals the capability of the NeQuick 2 and IRI Plas models to predict VTEC over the low latitude and South American sector is analyzed. ...
