Incoherent Scatter Facilities around the world

The Incoherent Scatter radars in regular use, at EISCAT, Sondrestromfjord, Millstone Hill, Arecibo, Jicamarca, Kyoto and Kharkov, make coordinated observations on several days each month, besides pursuing their individual programs. The data from these operations are routinely made available to the international scientific community.

New radars to study the ionosphere, and the lower and upper atmosphere, are currently being planned or constructed at Bukittinggi in Indonesia (on the Equator), Svalbard (1000 km north of Tromsų), Resolute Bay in Northern Canada, Fairbanks in Alaska and in Antarctica.

Research into the solar-terrestrial environment is coordinated on a world-wide basis under the auspices of various scientific commissions including IAGA/IAMAP, COSPAR, URSI and the ICSU Scientific Committee on Solar-Terrestrial Physics (SCOSTEP). One of the major programmes in the 1990's is the Solar-TerrestriEnergy Programme (STEP) whose major goal is to 'advance the understanding of the coupling mechanisms that are responsible for the transfer of energy and mass from one region of the solar-terrestrial system to another'.
