Abstract

The Atmospheric Chemistry and Climate Model Intercomparison Project (ACCMIP) was organized under the auspices of Atmospheric Chemistry and Climate (AC&C), a project of International Global Atmospheric Chemistry (IGAC) and Stratospheric Processes And their Role in Climate (SPARC) under International Geosphere Bisosphere Programme (IGBP) and World Climate Research Programme (WCRP). The Atmospheric Chemistry and Climate Model Intercomparison Project (ACC-MIP) consists of several sets of simulations that have were designed to facilitate useful evaluation and comparison of the AR5 (Intergovernmental Committee on Climate Change Assessment Report 5) transient climate model simulations.

This dataset contains measurements from climate simulations from LLNL of the 20th century and the future projections, which output feedback between dynamics, chemistry and radiation in every model time step. The data are collected from running the latest set of ozone precursor emissions scenarios, which output tropospheric ozone changes from 1850 to 2100.

Access rules:
Public data: access to these data is available to both registered and non-registered users.
Use of these data is covered by the following licence: http://creativecommons.org/licenses/by/4.0/. When using these data you must cite them correctly using the citation given on the CEDA Data Catalogue record.
Data lineage:

The ACCMIP model output uses CMOR (Climate Model Output Rewriter) to convert data to CF netCDF. The CMOR conversion is performed by the individual modelling groups and the resulting CF netCDF files are archived at CEDA.

Data Quality:
ACCMIP data arrives direct from the modelling centres. A versioning system ensures that new versions of data are placed in separate version directories.
File Format:
Data are netCDF formatted

Title CAM (global Community Atmosphere Model), the atmospheric component of the Community Earth System Model (CESM) deployed on LLNL (Lawrence Livermore National Laboratory) Computers
Abstract This computation involved: CAM (global Community Atmosphere Model), the atmospheric component of the Community Earth System Model (CESM) deployed on LLNL (Lawrence Livermore National Laboratory) Computers. CAM (Community Atmosphere Model) is the atmospheric component of CESM (Community Earth System Model), i.e. CESM-CAM. CESM-CAM-superfast has a simplified parametrized scheme; isoprene is the only NMVOC (Non-Methane Volatile Organic Compounds) taken into account. <div property="cedacat:introduction"> <div class="introduction">Introduction</div> <p>CAM (Community Atmosphere Model) is the atmospheric component of CESM (Community Earth System Model), i.e. CESM-CAM.</p> <p>CESM-CAM-superfast has a simplified parametrized scheme; isoprene is the only NMVOC (Non-Methane Volatile Organic Compounds) taken into account whilst exploring how changes in these drivers could affect tropospheric ozone abundances, from the pre-industrial period to future projections.</p> </div> <div property="cedacat:introduction"> <div class="introduction">Introduction</div> {insert content here} </div>
