Table 2-1 Table 2-1: Model representation/resolution. The table lists the horizontal representation and resolution; vertical coordinates and number of prognostic vertical levels (number below 800 hPa, above 200 hPa); and atmospheric bottom and top pressure levels, for a surface pressure of 1000 hPa. Hyperlinks connect to the summary report for each AMIP model version.
