The Canadian Downscaled Climate Scenarios-multivariate dataset for CMIP6 (Phase 6 of the Coupled Model Intercomparison Project) is a new set of downscaled scenarios based on the latest generation of climate projections from CMIP6. CMIP6 climate projections are based on updated global climate models and new emissions scenarios called “Shared Socioeconomic Pathways” (SSPs)1.
Statistically downscaled datasets are provided from 26 CMIP6 Global Climate Models (GCMs) (see below) under three different emissions scenarios (i.e., SSP1-2.6, SSP2-4.5, and SSP5-8.5) using the MBCn downscaling method2 and PCIC-Blend downscaling target data.
Annual values are available for over 30 different temperature- and precipitation-based indices, while seasonal and monthly values are available for a subset of these. Daily data for maximum and minimum temperature and daily precipitation are also provided. All data are available across Canada at a spatial resolution of ~6x10km for the 1950-2014 historical period and for the 2015-2100 period following each of the three emissions scenarios. Change values are calculated with respect to the 1971-2000 reference period.
Statistically downscaled multi-model ensembles have been constructed using output from 26 CMIP6 Global Climate Models (GCMs) that are available at the Earth System Grid Federation (ESGF) Data Nodes, (see below).
The N-Dimensional Multivariate Bias Correction (MBCn) downscaling method was applied, using PCIC-Blend as a target dataset.
All further climate index calculations were done using the ‘xclim’ Python package.
