[diegovillanueva]

Summary

Port applicable CESM2 SD parameter set to E3SMv3 (EAM) via a new namelist module micro_dv_nml.F90.

Parameters

Parameter	Type	Default	Description
hclas_du_imm/dep/cnt	real	1.0	Scale factors for dust het. freezing (immersion/deposition/contact)
hclas_bc_imm/dep/cnt	real	1.0	Scale factors for BC het. freezing
limfacdu	real	1.0	Max fraction of dust particles that can act as INP
onoff_contact_freezing	logical	.true.	Contact freezing on/off
rain_freeze	logical	.true.	Bigg rain-to-snow freezing on/off
onoff_sip	logical	.true.	Hallett-Mossop secondary ice production on/off
force_liquid_detrain	logical	.false.	Force all mixed-phase detrainment to liquid (applied in both macrop_driver and clubb_intr)
enable_nimax	logical	.true.	Enable ice number cap (nimax) in micro_mg_tend
