Many excellent sources of information are available about the structure of Earth's upper atmosphere, the space weather which occurs there, and the ways in which our planet is fundamentally coupled to our nearest star, the Sun.

Measurement Techniques: Incoherent and Coherent Scatter Radars

In order to study the upper atmosphere, we use ground based techniques to remotely obtain information on its behavior. One of these methods involves the use of incoherent scatter radar. This technique uses a powerful radiowave transmitter, large antennas, and sensitive receivers to remotely probe Earth's upper atmosphere at levels from 100 km to over 1000 km altitude.

Since atmospheric behavior changes as a function of geography, several such systems are located across the planet. In particular, The US National Science Foundation's Geosciences Directorate supports the operation of several radars through the Upper Atmosphere Facilities (UAF) program. This funding supports the Millstone Hill incoherent scatter radar as a key component of the Atmospheric Science Group's mission.

Other NSF UAF radars measure flow and dynamics of the mid to high latitude ionosphere through stronger coherent backscatter techniques using HF radar frequencies, coordinated through the SuperDARN project.
