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 with extensive datasets of satellite and ground-based observations collected ...

We used extensive measurements made by the Jicamarca Unattended Long-Term Investigations of the Ionosphere and Atmosphere (JULIA) and Incoherent Scatter Radar (ISR) systems at Jicamarca, Peru during geomagnetic quiet conditions to determine the climatologies of lunar tidal effects on equatorial vertical ...

The Jicamarca Radar Observatory is located near Lima, Perú [11°57'S, 76°52'W, magnetic dip 2°N], It consists of a 300 x 300 meter antenna (comprised of 9,216 crossed dipoles), several smaller antennas, 50 MHz transmitiera and receivers, and digital sampling and processing equipment centered around a ...

The purpose of this note is to report on ionospheric observations taken at Jicamarca (lº N Magnetic Latitude) during the March 8, 1970 magnetic storm. This report includes measurements of the electron density, electron temperature and vertical drift (or E-W electric field) for the 7, 8 and 9 of March ...

To qualify as an MST radar, the system has to be capable of obtaining echoes from the mesosphere. This requirement limits the frequency range of these radars to the lower frequencies of the VHF band, i.e., between 30 and 300 MHz. Smaller radars, using the same principles and techniques but capable of ...
