Temperature distributions (gray shades) on surfaces with constant optical depth at 5000 Å for arbitrary snapshots of the 3D models for HD 209458 (left) and HD 189733 (right). The spatial and temporal mean temperature stratification of the 3D models (green solid lines) is compared to 1D MARCS models (red solid lines) with the same stellar parameters. The dashed lines bracket the approximate height region between log τ₅₀₀₀ = 0 and log τ₅₀₀₀ = −2, from which the dominant contribution to the continuum surface brightness between the disk center at μ = 1.0 and the limb near μ = 0.01 is emitted.
