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 CCCma 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.

Title

Canadian Middle Atmosphere Model (CMAM) deployed on Canadian Centre for Climate Modelling and Analysis computing facility

Abstract

This computation involved: Canadian Middle Atmosphere Model (CMAM) deployed on Canadian Centre for Climate Modelling and Analysis computing facility. The Canadian Middle Atmosphere Model is a full general circulation model with on-line fully interactive chemistry involving 127 gas-phase and heterogeneous reactions. Thus, feedback between dynamics, chemistry and radiation occurs in every model time step.

The Canadian Middle Atmosphere Model is a full general circulation model with on-line fully interactive chemistry involving 127 gas-phase and heterogeneous reactions. Thus, feedback between dynamics, chemistry and radiation occurs in every model time step.
The model explores how changes in the levels and locations of ozone precursor emissions, (such as nitrogen oxides NO and NO; referred to as NO, carbon monoxide (CO) and volatile organic compounds (VOCs), including methane, could affect tropospheric ozone abundances, from the pre-industrial period to future projections.

The Canadian Centre for Climate Modelling and Analysis (CCCma) is a division of the Climate Research Branch of Environment Canada. The CCCma carries out research in modelling and analysis. The CCCma develop computer models of the climate system to simulate global climate, regional climate, and climate change.

The Canadian Centre for Climate Modelling and Analysis (CCCma) is a division of the Climate Research Branch of Environment Canada.
The CCCma carries out research in modelling and analysis.

The modelling component involves;

Developing computer models of the climate system to simulate global climate, regional climate, and climate change
Attributing observed climate changes to specific causes
Predicting seasonal and longer term climate variations
In order to undertake this research, the CCCma has an ongoing model development programme. Over the years, models of increasing sophistication have been developed, permitting study of more complex climate questions.

Under the analysis component, CCCma

Analyses past and predicted climate variations to gain a deeper understanding of the climate system
Provides science based quantitative information to the national and the international community, notably coordinated model experiments organized by the World Climate Research Programme (WCRP) and contributions to the Intergovernmental Panel on Climate Change
