iaero

Specifies aerosol model to use during the simulation

iaero=0 – No aerosol effects

iaero=1,-1 – Prescribed SO4 burden and direct aerosol effects.  Typically used for CMIP3 experiments.

iaero=2,-2 – Prognostic (single moment) aerosols based on CSIRO Mk3.6.  Includes direct and indirect effects and is typically used for CMIP5 experiments.

iaero=3,-3 – Same as for iaero=2,-2, but also includes aerosols in prognostic rain.  This option is currently experimental.

Negative values of iaero include additional aerosol information in the history file.
