An idealized, time-invariant, zonally averaged, zonally symmetric ozone dataset designed by the Aqua-Planet Experiment Project. Reformatted for use in CAM aqua-planet experiments: The original APE dataset was expanded to the 3 spatial dimensions and "time", mapped to the T42 (128x64) horizontal grid, mapped to 26 levels between 1003.69 and 0.28 hPa, and 12 copies of the time-invariant field created to represent a "monthly climatology" within the dataset. CAM uses the reforma...

Fully-coupled WACCM simulations with two different aerosol forcing files. The aerosol forcing files include background aerosols, but differ in that only one aerosol forcing file also includes explosive volcanic eruptions added to the background aerosols. Each ensemble contains 11 members with slightly varying initial conditions.
These simulation data are taken from aquaplanet and "real-Earth" configurations of the NCAR Community Climate System Model version 4 (CCSM4) and Community Earth System Model version 1.2.2 (hereafter, “CESM1”). The Community Atmosphere Model (CAM) is the atmospheric component of the climate model. Each file contains only a single data field (plus supporting data) for a single simulation. Only two primary data fields are provided in this collection: daily averaged total precipitation (PRECT) and t...
Output are from the CESM2(WACCM-X).The model’s dynamical fields (temperature, zonal and meridional winds and surface pressure) are specified in the troposphere and stratosphere from the Modern Era Retrospective Analysis for Research and Applications (MERRA) [Rienecker et al., 2011]. The model has a horizontal resolution of 1.9˚ latitude by 2.5˚ longitude. This simulation followed the “REFC1D” protocol of the Chemistry Climate Model Initiative [Eyring et al., 2013] for the specification of time-d...
Radiative kernels and forcing calculated with CESM1.1 (CAM5), large-ensemble version, for both the top-of-atmosphere and the surface. A demo usage script is also included.
The SO2 injection matrix simulations were performed to perform a system identification of the Whole Atmosphere Community Climate Model (WACCM), to identify the aerosol optical depth and climate response of stratospheric SO2 injections for different locations and amount. The WACCM model is a fully interactive Earth System Model, that includes interactive chemistry, radiations, dynamics and a whole atmosphere modal aerosol microphysical scheme, and is coupled to land, sea-ice and ocean (Mills et a...
The first simulations of stratospheric sulfate aerosol geoengineering using multiple injection locations to meet multiple simultaneous surface temperature objectives. Simulations were performed using CESM1(WACCM), a coupled atmosphere-ocean general circulation model with fully interactive stratospheric chemistry, dynamics (including an internally generated quasi-biennial oscillation), and a sophisticated treatment of sulfate aerosol formation, microphysical growth, and deposition. The objective...
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 pub...
Three sets of experiments as part of the Chemistry Climate Model Initiative project: REFC2 , G4SSA and G4SSA-S using the full tropospheric and stratospheric chemistry version of the Community Earth System Model – Community Atmospheric Model 4 (CESM CAM4-chem) with horizontal resolution of 0.9° x 1.25° lat-lon and 26 levels from the surface to about 40 km (3.5 hPa). Each set of experiment has three ensemble members. RCP6.0 is the reference run from 2004 to 2089, and G4SSA and G4SSA-S are two sol...

Among other forcings, past climate variations have been driven by changes in Earth’s orbit and greenhouse gas concentrations. These forcings often change concurrently, making it difficult to isolate specific climate responses from the paleoclimate record alone. Here, simulations are run with the NCAR CESM1.2 to isolate the climate responses to different past forcings. In each simulation, only one boundary condition is changed while others remain fixed at preindustrial levels, with the goal of...
Output are from the CESM2(WACCM-X 2.0). These are results from a free running historical simulation. The model has a horizontal resolution of 1.9˚ latitude by 2.5˚ longitude. This simulation followed the “REFC1D” protocol of the Chemistry Climate Model Initiative [Eyring et al., 2013] for the specification of time-dependent greenhouse gases and ozone depleting substances. Data are provided for evaluation/validation purposes. Please contact marsh@ucar.edu for terms of use.

These data are from a series of simulations documenting model developments that have been included in Community Land Model version 5 (CLM5) which is the default land component for the Community Earth System Model version 2 (CESM2).

Increasing the resolution...
Stratospheric Aerosol Geoengineering experiments have been produced by CESM2(WACCM6). Two experiments have been performed following the CMIP6 WACCM6 SSP5-34-OS experiment as a baseline scenario with stratospheric sulfur injections to limit global warming to 1.5C or 2.0C above 1850–1900 conditions, called Geo SSP5-34-OS 1.5 and Geo SSP5-34-OS 2.0, respectively. A third experiment has been performed that follows CMIP6 WACCM6 SSP5-85 as a baseline and to limit global warming to 1.5oC, called Geo SS...

To gain insight into the atmospheric teleconnections associated with the AMV, we perform idealized experiments using Community Earth System Model version 1 (CESM1) in which North Atlantic SSTs are restored to a time-independent spatial pattern corresponding to an estimate of the internal component of the observed AMV anomaly (see Ruprich-Robert et al. (2017) for more details). CESM1 uses nominal 1˚ horizontal resolution in all its components. Because we aim to assess the effects of internal vari...

Test description
The relative importance of radiative feedbacks and emissions scenarios in controlling surface warming patterns is challenging to quantify across model generations. We analyze three variants of the Community Earth System Model (CESM) with differing equilibrium climate sensitivities (ECS) under identical CMIP5 historical and high-emissions scenarios. CESM1, our base model, exhibits Arctic-amplified warming with the least warming in the Southern Hemisphere middle latitudes. A variant of CESM1 with ...
Robust and nonrobust aspects of Atlantic meridional overturning circulation (AMOC) variability and mechanisms are analyzed in several 600-yr simulations with the Community Earth System Model. The simulations consist of a set of cases where a few loosely constrained ocean model parameter values are changed, a pair of cases where round-off level perturbations are applied to the initial atmospheric temperature field, and a millennium-scale integration. The time scales of variability differ among th...
