INFORMATION

Anne Frigonprojet@ouranos.ca 514-282-6464www.ouranos.ca

Weather stations across the Quebec territory are sparse and in operation over varying and often short periods of time. Furthermore, the data they produce contain a limited number of meteorological variables. The incomplete coverage of the territory, both spatially and temporally, makes it difficult to produce an accurate picture of the Quebec climate and its meteorological history. This difficulty is particularly pronounced for users who need variables other than temperature and precipitation as well as for those interested in Quebec’s northern territory, where monitoring stations are few and located almost exclusively along the coast.

Produce, using the new version of the Canadian Regional Climate Model (CRCM5), a comprehensive climatology of Quebec in order to provide the best possible approximation of the weather conditions of the last 30 to 40 years.Update available data based on the evolution and the development of the CRCM5 and on new opportunities for performing simulations (e.g., availability of new driving data).

Use of the latest version of the CRCM5 to produce the climatology of the recent climate of Quebec, allowing for a more refined spatial resolution of the reanalyses.Meetings with users to define their needs and expectations in this project.Updating of the database based on the evolution of the CRCM and the driving data available in each phase.

Provision of a database of meteorological variables of the recent climate history covering the Quebec territory.Report presenting a brief overview of the errors and uncertainties of this database.

PROJECT IN PROGRESSCLIMATE RECONSTRUCTION AT OURANOS FOR QUEBEC (CROQ)

Overall, this project will allow developing a better picture of the climate in Quebec, especially with regard to those regions on which there is no historical meteorological data. These latter regions include a large part of northern Quebec, which are increasingly targeted for development.This project will provide a number of researchers in vulnerability, impacts and adaptation (VIA) access to a new and revised body of historical meteorological data, allowing them to calibrate their impact models. The project will also raise the level of knowledge which Ouranos and its partners have of the Quebec climate, thereby contributing to the advancement of adaptation research.

The CRCM5 was developed by the ESCER centre of UQÀM (www.escer.uqam.ca) in collaboration with Environment and Climate Change Canada.

CRCM5 computations were made on thesupercomputer guillimin from McGillUniversity, managed by Calcul Québecand Compute Canada.
