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.

| 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.

| 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 simpli&#64257;ed parametrized scheme; isoprene is the only NMVOC (Non-Methane Volatile Organic Compounds) taken into account whilst exploring how changes in these drivers could a&#64256;ect 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> |
