Welcome to our HAARP riometer home page!
We are a research group within the Institute
for Physical Science and Technology at the University
of Maryland. The projects that our group is involved with examine natural
phenomena occurring in the Earth's atmosphere, ionosphere, and magnetosphere.
The broad focus of this research is directed toward improved understanding
of the mechanisms which couple solar processes into the terrestrial environment.
These include investigations of phenomena associated with short-term environmental
effects (auroras, induced electrical currents, radiowave communications
interference), as well as those associated with longer-term effects (changes
in the ozone layer, atmospheric composition studies, stratospheric winds,
weather, climate). The Upper Atmospheric Physics group operates or co-operates
both imaging and broadbeam riometers at many locations worldwide.
