The number of simulations depends on variables and scenarios. |

RCP 2.6 |
Meteorological (daily minimum and maximum temperature, precipitation, specific humidity, and incoming solar radiation; two derived variables are also provided: relative humidity and daily mean temperature.) |
Data in netCDF format can be accessed from the NA-CORDEX search page by selecting mbcn-Daymet in Bias Correction section. CAUTION: There was previously an error affecting all of the bias-corrected data (all mbcn-gridMET and mbcn-Daymet files) in the NA-CORDEX archive. A description of the error can be found below. As of 2021-11-19, this error has been fixed. The bias-correction was re run for all data published through the NCAR Climate Data Gateway and verified that the error was no longer present. If you downloaded bias-corrected data before 2021-11-19, you should replace it with the new version. Bias-adjusted CORDEX data in netCDF format are also available on ESGF nodes under the “CORDEX-Adjust” project (from all CORDEX search options chose “Domain”, “RCM Model”, “Driving Model”, “Downscaling Realisation” and “Bias-adjustment”) at the following ESGF Tier 1 nodes:

PCIC has available for download all daily data (for each of the 24 climate models) in netCDF and ASCII formats. ClimateData.ca permits the download of daily data (for each of the 24 climate models) for specific locations in netCDF or CSV format. The site also offers climate indices (annul, seasonal and monthly) based on the daily BCCAQv2 data, as well as the possibility to compute online indices with specific thresholds (the ensemble for indices is represented by the 5th, 25th, 50th, 75th and 95th percentiles). Data for a single point can be downloaded as a CSV or JSON. ECCC’s climate scenarios page also provides access to various climate indices in netCDF format. The CCCS website permits to download the ensemble percentiles (5th, 25th, 50th, 75th and 95th) for the annual, seasonal and monthly absolute values of daily minimum, maximum and mean temperature and total precipitation as well as of anomalies computed with respect to the reference period of 1986-2005.
