CESM2.1-CAM6-CLM4 2-degree amip-LGM

Monthly mean RFMIP-like data from a 30-year simulation of CESM2 configured with CAM6 with finite-volume dynamical core on 2-degree grid and CLM4 as land model. Boundary conditions from Pedro DiNezio for last glacial maximum. The new gravity wave scheme in CAM6 is <strong>disabled</strong> in these simulations because the topography file used is incompatible.
