NICAM#
Model description#
NICAM is a non-hydrostatic icosahedral atmospheric model (Tomita and Satoh, 2004) with an explicit cloud microphysics scheme. A configuration used in the DYAMOND project is similar to that described by Kodama et al., 2015.

Data structure#
Vertical#
The number of vertical levels is 78, and the interval between each vertical level is increased from the ground to the model top. An attached ASCII file is the geometric height of vertical model levels used in NICAM.
Horizontal#
The horizontal grid spacing in the experiments was set to 3.5 km (Grid Level; GL11), 7.0 km (GL10) and 14 km (GL09).
