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 disabled in these simulations because the topography file used is incompatible.
