Slide image: Stills from two animations showing lower thermosphere and mesosphere dynamics being studied by the Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED) Doppler Interferometer (TIDI). The animation stills are labeled as follows:
TIDI Winds 2002078 to 2002140
Meridional Wind (cold side) 72.5 to 97.5 km Solar Local Time: 10.96 (left)
Zonal Wind (cold side) 72.5 to 97.5 km Solar Local Time 10.96 (right)
