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

[ Get Data ]

Abstract: 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

TIDI data products consist of line-of-sight (LOS), wind profiles and
wind vectors.
