.. _NICAM-DYAMOND-SUMMER: 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 `__. Contact ~~~~~~~ `Ryosuke Shibuya `__ and `Chihiro Kodama `__, Japan Agency for Marine-Earth Science and Technology (JAMSTEC), JP 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). Data access ----------- Output variables are given below. A more detailed listing in terms of namelist descriptions, including the names of the files which contain corresponding variables, can be found `here `__. **Land output, Output Interval: PT03H**
