Abstract

Data from the Environment and Climate Change Canada (CCCma) Canadian Middle Atmosphere Model (CMAM) model simulations, part of the International Global Atmospheric Chemistry (IGAC)/ Stratosphere-troposphere Processes and their Role in Climate (SPARC) Chemistry-Climate Model Initiative phase 1 (CCMI-1).

CCMI-1 is a global chemistry climate model intercomparison project, coordinated by the University of Reading on behalf of the World Climate Research Programme (WCRP).

The dataset includes data for the following CCMI-1 experiments:
Reference experiments: ref-C1, ref-C1SD and ref-C2.
Sensitivity experiments: senC2CH4rcp85, senC2fCH4, senC2fGHG, senC2fN2O, senC2fODS, senC2rcp26, senC2rcp45 and senC2rcp85.

ref-C1: Using state-of-knowledge historic forcings and observed sea surface conditions, the models simulate the recent past (1960–2010).
ref-C1SD: Similar to ref-C1 but the models are nudged towards reanalysis datasets, and correspondingly the simulations only cover 1980–2010. (“SD” stands for specified dynamics.)
ref-C2: Simulations spanning the period 1960–2100. The experiments follow the WMO (2011) A1 baseline scenario for ozone depleting substances and the RCP 6.0 (Meinshausen et al., 2011) for other greenhouse gases, tropospheric ozone (O3) precursors, and aerosol and aerosol precursor emissions.
senC2CH4rcp85: Similar to ref-C2 but the methane surface-mixing ratio follows the RCP 8.5 scenario (Meinshausen et al., 2011), all other GHGs and forcings follow RCP 6.0.
senC2fCH4: Similar to ref-C2 but the methane surface-mixing ratio is fixed to its 1960 value.
senC2fGHG: Similar to ref-C2 but with greenhouse gasses (GHGs) fixed at their 1960 levels, and sea surface and sea ice conditions prescribed as the 1955–1964 average (where these conditions are imposed).
senC2fN2O: Similar to ref-C2 but the nitrous oxide surface-mixing ratio is fixed to its 1960 value.
senC2fODS: Similar to ref-C2 but with ozone-depleting (halogenated) substances (ODSs) fixed at their 1960 levels.
senC2rcp26: The same as ref-C2, but with the GHG scenario changed to RCP 2.6 (Meinshausen et al., 2011).
senC2rcp45: The same as ref-C2, but with the GHG scenario changed to RCP 4.5 (Meinshausen et al., 2011).
senC2rcp85: The same as ref-C2, but with the GHG scenario changed to RCP 8.5 (Meinshausen et al., 2011).

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
