MODELING OF THE ATMOSPHERE MAGNETOSPHERE IONOSHERE SYSTEM MAMI

The effects on the terrestrial atmosphere and ionosphere of energy and momentum sources of magnetospheric origin are investigated theoretica lly. Parameters measured by instruments on board the GGS spacecraft an d by the GGS ground-based networks are used as inputs to the models th at quantify the magnetosphere-ionosphere-thermosphere coupling. Images of the aurora acquired at ultraviolet, visible and X-ray wavelengths by instruments on board the POLAR spacecraft are particularly useful i n this investigation by yielding good spatial coverage and high time r esolution of the aurora.
