Description:

• WIEMIP spinups with CH4 and fire calibrations discussed in WIEMIP, Hillslope & CH4 setup #162, after resolving initial fire issues in Hillslope cases discussed in ctsm5.4.022_BGC_hillslope_f09_147_ [AD, SASU, pSASU, HIST] #147.
• Usermods as discussed in Setting up WIEMIP Transient runs #165

Diagnostics showing a quick look at the model state after 180 y AD spinup seems reasonable, here compared to pSASU in #158 (a flat case with WIEMIP surfacedata & DATM).

• Burned area, CH4, GPP, and TOTVEGC all seem reasonable, with
• Slightly higher ecosystem fluxes & state in the hillslope case, as expected

@swensosc, @lifang0209, @linniahawkins thanks for your help getting this run going! Let me know if you see any red flags for WIEMIP.

Looking good - carbon cycle is robust but not Carboniferous.

Created /glade/work/wwieder/wiemip/wetlands.n03.ctsm5.4.029_f09noCrop_HH_165_SASU_b, same as the SASU case, but starts after 601 years of AD spinup.

• The 165_SASU case started after 360 years of AD spinup, but TOTECOSYSC didn't come into equilibrium until 400 years of AD spinup and > 3% of land surface was still not in equilibrium after 600 years!

pSASU diagnostics vs 164, the parallel 'flat' case

pSASU diags for a second hillslope case that had a longer AD spinup (and came into equilibrium faster in pSASU)
