ne30 | ne120 before 8/10/16 | ne120 after 8/10/16 | Explanation | |
---|---|---|---|---|
dtime | 30 min | 15 min | 15 min | Timestep used for most physics processes and for coupling between physics and dynamics |
se_nsplit | 2 | dtime/se_nsplit = time between vertical remaps of the semi-Lagrangian vertical coordinate. | ||
se_qsplit | 1 | dtime/(se_nsplit*se_qsplit) = timestep used for tracer advection | ||
se_rsplit | 4 | dtime/(se_nsplit*se_qsplit*se_rsplit) = timestep used for dynamics calculations | ||
hypervis_subcycle | 3 | dtime/(se_nsplit_se_qsplit*se_rsplit*hypervis_subcycle) = timestep used for hyperviscosity calculation | ||
cld_macmic_num_steps | 6 | Number of times the code surrounding macrophysics + microphysics is subcycled. This means that dtime/cld_macmic_num_steps = timestep used for macrophysics and microphysics. | ||
clubb_timestep | 300 sec | I'm not sure what this means or how it relates to cld_macmic_num_steps | ||
IRADSW | 2 steps | How frequently to compute SW radiation (in timesteps). Radiation tendencies are taken from previous steps for steps when radiation is not recalculated. I think some scaling is made to account for zenith angle changes? | ||
IRADLW | 2 steps | How frequently to compute LW radiation (in timesteps). Radiation tendencies are taken from previous steps for steps when radiation is not recalculated. I think some scaling is made to account for zenith angle changes? |
