Figure 2.2: Eta-22 (left panels) and Eta-12 (right panels) surface height (m)
over the Western U.S (top) and Eastern U.S. (bottom). Since these figures depict the
actual step-mountain orography (discretized to the eta interfaces) the color shading
will not agree between the Eta-22 and Eta-12 because of the differing vertical
distribution of eta levels.
