- ! When we have daily rather than annual glacier dynamics (as we do in this testmod, due
- ! to having test_coupling in user_nl_cism), CLM applies the dynbal adjustments in a
- ! single time step rather than spreading them throughout the year. This can cause
- ! sensible heat fluxes of thousands of W m-2, which causes CAM's PBL scheme to blow up.
- ! So force these fluxes to zero for this testmod; this breaks water and energy
- ! conservation in CLM, but should allow the test to pass.
