• hydrostatic, shallow-atmosphere
• icosahedral, hexagonal, C-grid, structured
• pressure-based hybrid terrain-following eta coordinate
• Lorentz vertical staggering
• mass- and enstrophy-conserving finite differences based on the vector-invariant form (Sadourny, 1975 ; Ringler et al., 2010)
• explicit 4-th order dissipation
• Eulerian positive definite, slope-limited transport (Dubey et al., submitted)

Please replace the text below with the model-specific information. The text just serves as a guide. If the model uses an acronym to denote its typical horizontal resolution (e.g. ni48) please identify it in column 1 in the Table below. It will be especially helpful to list resolutions that approximate a grid spacing of 2 deg, 1.5 deg. 1 deg, 0.5 deg and 0.25 deg. These correspond to equatorial grid spacings of about 220 km, 165 km, 110 km, 55 km and 28 km, respectively, and represent the horizontal grid spacings recommended for the test cases.
Please list all resolution-dependent dissipation coefficients that are typically utilized at these resolutions (e.g. 4th-order diffusion coefficient, 2nd-order diffusion coefficient, divergence damping coefficient, ...)
If the dissipation method and its potential coefficent does not depend on the resolution (e.g. coefficient for a temporal Robert-Asselin filter in case of a leapfrog scheme, order of Shapiro filter, polar FFT filter, etc. ) please list the mechanism and its coefficient (if applicable) in the text here.
