SUPPLEMENTAL FIGURE CAPTIONS

Supplemental Figure 1:
(a) Mean differences of zonal mean HIRDLS V7 GPH with respect to WACCM for 2005-2007, (b) standard deviations of same differences, all in meters.

Supplemental Figure 2: 
 (a) HIRDLS V7 mapped zonal geostrophic winds for sample day 2006d138 at levels 1 and 100 mb, (b) WACCM mapped zonal winds for the same sample day and levels, (c) HIRDLS V7 – WACCM mapped zonal winds for same sample day and levels, all in meters per second. Values within 15 degrees of the Equator were discarded (because of the Coriolis factor).

Supplemental Figure 3:
 (a) HIRDLS mapped meridional geostrophic winds for sample day 2006d138 at 1 and 100 mb, (b) WACCM mapped meridional winds for the same sample day and levels, and (c) their differences, all in meters per second. Values within 15 degrees of the Equator were discarded.
