Wind speed and direction from DWE and DISR

This figure shows horizontal wind speed and direction as a function of altitude from DWE and DISR. The green lines are the DISR data and the blue lines are the high-altitude DWE data (showing reasonable consistency between the two).

Titan’s eastward winds slow from about 28 m/s at 50 km to 10 m/s near 30 km, then decrease more rapidly down to 7 km where they drop to zero. Below 7 km, the expected top of the boundary layer, the winds reverse and blow westward.
