CESM2 Large Ensemble

The CESM2 Large Ensemble (LENS2) is a 100-member ~1.0° ensemble covering the period 1850-2100. It provides restart files that can be used to initialize a CESM ensemble.

The ensemble is constructed in a way that samples internal variability throughout an extended pre-industrial control simulation:

Members 11-90: “The chosen start dates (model years 1231, 1251, 1281, & 1301) sample AMOC and sea surface height (SSH) in the Labrador Sea at their maximum, minimum, and transition states.”
