A general question about selecting the right compset to study permafrost

[MS_CLM]

I would like to (historical) model and (future) project responses of the Canadian permafrost thermal state to climate change on the coupled energy-water-carbon fluxes using the CLM model. For this purpose, which component set do you recommend to use?

I have compiled the CLM model (support level: Defined) with I2000Clm50Cn at ~50km grid resolution (f05_g17, lnd:0.47x0.63); this compset (which, includes land, land-ice, carbon model, river-runoff etc.,) seems to be a right choose for my research.

Any recommendations please?

I would recommend reading this paper that discusses improvements in CLM5BGC with regard to permafrost:
