Experiments with Aeolus, land_lad, and LPJ

Derived after mom5_CM2_lad_05LPJ_05_Xcoarse

MOM5 setup from  CM2M_coarse_BLING
  See also the README for the om3Xcoarse setup.
land_lad from CM2M_coarse_BLING but regridded to 0.5x0.5 degree resolution.
LPJ with newly-made configuration to match the regridded land_lad land-sea mask.
Aeolus atmosphere.
