  1. Lake numbers (#), surface area (SAC), dynamic ratio (DRC), maximum depth (ZmaxC), mean depth (ZmeanC), vertically resolved mean water temperature when weighted by volume (wTmeanC), volume (VC), fraction of epilimnetic volume (fVEpiC), fraction of epilimnetic sediment surface area (fAEpiC), ratio of epilimnetic volume to epilimnetic sediment surface area (VEpiC / AEpiC). Throughout this table, N-G refers to non-glaciated and Temp. to temperate regions, and ‘C’ refers to composite value across the parameters.
