 Tabulated are the number of columns (# _{Mcol}, in millions), the vertical levels (# _{lev}, not counting soil levels), the microphysical variables (# _{μ}), the linear dimension of the area, the A of the largest tile (\(\sqrt {A_{\text {max}}}\)), the vertical span of the column (H_{top}), and the height (H_{spng}) where the sponge layer begins. The last three columns denote parameterization assumptions. For cumulus parameterization (denoted CP), the letters “N,” “S,” and “F” denote none, shallow, or full parameterization, whereby for the latter, some assumptions are usually included in an attempt to account for the scale of motions being parameterized. For the boundary layer parameterization (denoted BL), the letters “T,” “K,” and “S” denote either a TKElike model (including an additional prognostic equation), a diagnostic eddy diffusivity, or a Smagorinskylike threedimensional closure as is common for largeeddy simulation. Finally, some indication is given as to whether fractional cloudiness (denoted FC) is parameterized
