Description:
The CESM Large Ensemble Project is a publicly available set of climate model simulations intended for advancing understanding of internal climate variability and climate change. All simulations are performed with the nominal 1-degree latitude/longitude version of the Community Earth System Model version 1 (CESM1) with CAM5.2 as its atmospheric component. The Large Ensemble Project includes a 40-member ensemble of fully-coupled CESM1 simulations for the period 1920-2100. Each member is subject t…

Description:
The CESM Decadal Prediction Large Ensemble (DPLE) is a set of simulations carried out at NCAR to support research into near-term Earth System prediction. The DPLE comprises 62 distinct ensembles, one for each of 62 initialization times (November 1 of 1954, 1955, ..., 2014, 2015). For each start date, a 40-member ensemble was generated by randomly perturbing the atmospheric initial condition at the round-off level. The simulations were integrated forward for 122 months after initialization. Obse…

Description:
The Stratospheric Aerosol Geoengineering Large Ensemble project (GLENS) is a 20-member ensemble of stratospheric sulfate aerosol geoengineering simulations between 2020-2099 and a 20-member ensemble of control simulations over a reference period between 2010-2030 using the NCAR Community Earth System Model with the Whole Atmosphere Community Climate Model as its atmospheric component.

Description:
The CESM1-CAM5 fixed ozone runs are eight CESM simulations that use the Large Ensemble (LENS) code base and were initialized in 1955 with Large Ensemble members. The runs use the same external forcings as those in the 20th Century CESM LENS except for ozone. Instead of prescribing a time-varying ozone concentration as in LENS, ozone is kept at constant 1955 concentrations. (The ozone file is available under the Data Access tab.) Note that the global ozone concentrations are fixed, including bot…

Description:
This dataset contains processed data from the CESM2 single forcing large ensemble experiments as well as some CESM2 emissions files that are necessary for reproducing the figures in Simpson et al (2023) "The CESM2 Single Forcing Large Ensemble and Comparison to CESM1: Implications for Experimental Design", Journal of Climate.

Description:
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 compl…

Description:
This 30-member ensemble of CESM1 and WACCM hindcast simulations for the 1979-2014 period is produced using the fully coupled CESM1 simulations and that of a high-top atmosphere-only Whole Atmosphere Community Climate Model (WACCM) as its component. This project is created by researchers at WHOI in collaboration with NCAR researchers.

Description:
The CESM2 "Single Forcing" Large Ensemble Project is a publicly available set of climate model simulations useful for addressing the roles of individual forcings in historical and future climate change. This simulations use the same model and forcings as the CESM2 Large Ensemble Project and, therefore, can be used to parse the relative roles of different forcings in responses found in that ensemble where all forcings are applied together. The ensemble members are initialized from 1850 from the …

Description:
The CESM2 Large Ensemble consists of 100 members at 1 degree spatial resolution covering the period 1850-2100 under CMIP6 historical and SSP370 future radiative forcing scenarios. Two separate sets of biomass burning emissions forcing files were used within the ensemble. Members 1-50 were forced with CMIP6 protocols identical to those used in Danabasoglu et al. (2020) in the paper for CESM2. For members 51-100, the most relevant species for biomass burning fluxes from the CMIP6 protocols were s…

Description:
There is growing evidence that the role internal variability plays in our confidence in future climate projections has been under-appreciated in past assessments of model projections for the coming decades. In light of this, a 15 member ensemble has been produced to complement the existing 30 member "Large Ensemble" conducted with the Community Earth System Model (CESM). In contrast to the Large Ensemble, which explored the variability in RCP8.5, our new ensemble uses the moderate mitigation sc…
