Table 2-14 Table 2-14: Surface characteristics. The table shows whether the surface roughness (or, alternatively, the surface drag coefficient) is spatially variable over ocean, land, or sea ice. The table also shows whether the albedo of any surface depends on solar zenith angle or spectral interval, and whether there is graybody longwave emission (emissivity e < 1.0) from any surface. Hyperlinks connect to the summary report for each AMIP model version.
