• Canadian Regional Climate Model (CRCM)

• ARPEGE_Climat_Ouranos v4.4

We present here the CRCM approach, a general description of the CRCM and information on different CRCM versions used to produce climate change simulations.

More specific information on the configuration of the CRCM to produce some of these climate change simulations, along with monthly data are available from CCCma's data section.

More information on the CRCM and its different versions is available from CCCma's model section, while information on the regional model's applications and validation can be found on the Canadian Regional Climate Modelling Network.

CRCM DATA

The source of the CRCM data should be acknowledged with the following citation:

"The CRCM time series data has been generated and supplied by Ouranos' Climate Simulations Team."

The right references need to be cited using the relevant publications according to the chosen experiments and versions of the CRCM model (see http://loki.qc.ec.gc.ca/DAI/mrcc_exp-e.html).

Please note that on average, the delay of processing for a CRCM data request is 5.17 days.

Through a collaboration established with Météo-France, a first climate projection using the french model ARPÈGE version 4.4 was produced at Ouranos (recent past : 1958-2001, and future climate following SRES A2 : 2038-2081). The grid configuration developed for this purpose is a global spectral grid with a resolution of T159, stretched with a factor of 2.5, and centered at 50°N - 95°W (e.g. Winnipeg, see the orographic mask over North America).

Please note that the ARPEGE data available through the DAI web site are defined on the Polar Stereographic grid of the CRCM, i.e. AMNO grid defined with 182 x 174 grid points (see the land-sea mask)

The source of this model datasets should be quoted in the same way as those for the CRCM : 'The ARPEGE time series data has been generated and supplied by Ouranos' Climate Simulations Team, with a special acknowledgement addressed to Météo France who has provided the ARPEGE_Climat_Ouranos v4.4 and its scientific support to make possible the simulations' and with reference to the relevant publication for the chosen experiment and the model (for the ARPEGE_Climat_Ouranos v4.4, see Déqué and Piedelievre, 1995; Déqué et al., 1998; Gibelin and Déqué, 2003).
