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...
An ensemble member of CESM1(BGC) using the RCP8.5 forcing scenario to 2300, using prescribed CO2 concentrations. Described in the manuscript: J. T.
