The Ionospheric Monitoring Group Introduction The Rutherford Appleton Laboratory operates ionosondes at RAL (Chilton) in the UK and at Port Stanley in the Falkland Islands. Until June 1998 there was a third instrument at Lerwick in the UK. Ionograms and scaled URSI parameters from all three stations are archived in the WDC. The RAL ionosonde has replaced the instrument that was previously ...

Ionosphere (Earth's) spaceweb@oulu.fi - last update: 25 November 1998, 0830 UT (RR) Introduction Because of the Sun 's UV radiation, Earth 's upper atmosphere is partly (0.1% or less) ionized plasma at altitudes of 70-1500 km. This region, ionosphere, is coupled to both the magnetosphere and the neutral atmosphere. It is of great practical importance because of its effect on radio waves. The ...

Lancaster University Ionosphere and Radio Propagation Group Welcome to the IRPG Home Page The main interests of the group lie in the study of high latitude ionospheric radio absorption events and their effects on HF propagation. The group has been involved in the installation of an Imaging Riometer for Ionospheric Studies (IRIS) at Kilpisj rvi, northern Finland. The system has been in operation ...

Magnetosphere Ionosphere and Solar-Terrestrial MIST is an informal community of UK-based scientists who study the ionosphere and magnetosphere and the ionised space in the vicinity of Earth (sometimes known as `geo space') , and solar-terrestrial relations, i.e. the influence which the `solar wind' and solar radiation have on the plasma of geospace and hence indirectly on the Earth itself.

Modeling of the Atmosphere Magnetosphere Ionosphere System (MAMI) Welcome to the home page of the MAMI investigation at the Geophysical Institute (Space Physics Group) of the University of Alaska, Fairbanks. This investigation is part of the International Solar Terrestrial Project (ISTP). This program combines satellite and ground based observations with theory and modeling to better understand ...

TIMED will provide a benchmark for future studies of natural and human-induced changes to the Earth's atmosphere, providing an avenue for early warning of global change. TIMED, a small remote sensing and imaging spacecraft, will achieve quantitative understanding of the energetics and dynamics of the Mesosphere and Lower Thermosphere-Ionosphere (MLTI) between ~50 and 200 km. The MLTI is a ...

Earth - Auroras and the Ionosphere Can aurora or the Earth's magnetic field be harnessed to make energy Is there a monument to the Northern Lights somewhere Do sunspots affect the brightness and color of aurora How much power do aurora produce and can we use it Do aurora produce infrared emission When can I see the Northern Lights from North America Why do we use X-rays to study aurora

Last modified June 2 1998 E-mail: demerson@nrao.edu Elliptical Polarization in the Ionosphere. Darrel Emerson Feb/May 1998 Summary: This article calculates the degree to which a 100% linearly polarized wave will become elliptically polarized in its passage through the ionosphere. Although valid over a wider range of frequencies, sample calculations concentrate on the VHF range of frequencies.

The ionosphere is the ionized component of the Earth's upper atmosphere. Two different ionization processes are involved in its creation: photoionization, principally by solar extreme ultraviolet (EUV) and x-ray photons, and impact ionization by charged particles (including solar and galactic cosmic rays). During the daytime and at subauroral latitudes, photoionization is the dominant process, ...

The Effects of Earth's Upper Atmosphere on Radio Signals Needed Materials 1.) AM radio 2.) Aluminum screen (can be purchased at home supply store such as Home Depot) Introduction The electromagnetic spectrum consists of waves of many wavelengths ranging from very long wavelength radio waves to very short wavelength gamma rays. Visible light, consisting of short wavelength waves, is placed near ...
