TIMED Doppler Interferometer (TIDI) Data from the Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics (TIMED) Mission

The TIMED Doppler Interferometer (TIDI) is one of four instruments that constitute the TIMED spacecraft, the first mission of the NASA Solar Connections program. The TIDI interferometer (or Profiler) primarily measures horizontal vector winds from the Earth's limb, with a vertical resolution 2.5 km and with an accuracy that approaches ~3 m/sec under optimum viewing conditions. The TIDI design allows for 100% duty cycle instrument operation during daytime, nighttime, and in auroral conditions. TIDI views emissions from OI 557.7 nm and O2(0-0) to determine Doppler wind. TIDI data products consist of line-of-sight (LOS), wind profiles and wind vectors. See "http://tidi.engin.umich.edu/"
