Figure 9From: The dynamics of the mesosphere and lower thermosphere: a brief review Maps of absolute GW momentum flux as a function of height. Distributions of momentum flux derived from TIMED/SABER observations for January (left, (a), (c), (e)) and July (right, (b), (d), (f)) 2006 at altitudes of 30, 50 and 70 km. Values are in log10 Pa.
