CESM1 Last Millennium Ensemble
d651058
The CESM Paleoclimate Working Group at NCAR conducted a series of Last Millennium community experiments, referred to as the Last Millennium Ensemble (LME). The LME used a ~2-degree atmosphere and land, ~1-degree ocean and sea ice version of CESM1 (CAM5). Ensemble members extend from 850 to 2006 using reconstructions for the transient evolution of solar intensity, volcanic emissions, greenhouse gases, aerosols, land use conditions, and orbital parameters, together and individually. We have completed 36 simulations for the LME project: 13 simulations with all transient forcings, smaller ensembles with each transient forcing separately, and long 1850 and 850 control simulations. Ensemble spread is generated using round-off differences in the initial atmospheric state. Monthly, daily, and 6-hourly outputs are available. More information about this dataset can be found on the CESM1 Last Millennium Ensemble Project website [https://www.cesm.ucar.edu/community-projects/lme].
