Updates and errata

Table of updates (2016-2019)

Page Item Date
Historical gridded snow water equivalent and snow cover fraction over Canada from remote sensing and land surface models Observation-based datasets of monthly snow cover fraction (SCF), monthly snow water equivalent (SWE), and annual maximum snow water equivalent (SWEmax) over Canada for 1981-2016 are available for download. 2019-12
Historical climate indices Derived historical temperature and precipitation indices based on daily adjusted and homogenized climate datasets are available for download through a user-friendly interface. 2019-12
Canada's Changing Climate Report supplemental datasets Datasets of multi-model temperature and precipitation projections for Canada for 2031-2050 under the low-emission (RCP2.6) and high emission (RCP8.5) scenarios are available for download. 2019-12
Seasonal forecasts Starting August 1 2019, seasonal forecasts are produced using an updated numerical weather prediction model. Please see this technical document for more details. 2019-08
CMIP5 Graphics and Tables The table of projected changes in temperature for December-February (specifically for 75th percentile) and tables of projected changes in snow depth have been updated. This affects all users who have referred to these tables prior to July 17 2019. 2019-07
Standardized Precipitation Evapotranspiration Index Standardized Precipitation Evapotranspiration Index (SPEI) datasets calculated using global climate model projections from the Coupled Model Intercomparison Project Phase 5 (CMIP5) are available for download. 2019-04
Downscaled indices Statistically downscaled climate indices related to temperature, precipitation and agroclimate are available for download. The indices are based on model projections from 24 global climate models (GCMs) that participated in the Coupled Model Intercomparison Project Phase 5 (CMIP5). 2019-04
Statistically downscaled climate scenarios Statistically downscaled climate model data based on Coupled Model Intercomparison Project Phase 5 (CMIP5) model output are now available. The data was downscaled using the Bias Correction/Constructed Analogues with Quantile mapping version 2 (BCCAQv2). 2018-11
Seasonal forecasts

Seasonal forecasts, including national and global probabilistic forecasts of temperature, precipitation, sea surface temperature, snow water equivalent, surface solar radiation, cloud fraction and specific humidity, are available

CMIP5 Graphics and Tables Maps, time series plots and tables of projected annual change in temperature, precipitation, snow depth, sea ice concentration, sea ice thickness and wind speed are available. 2016-10
CMIP5 Graphics and Tables and CMIP5 Gridded Data The variables, sea ice thickness, sea ice concentration, snow depth, and near-surface wind speed, are available. 2016-04
CMIP5 Graphics and Tables

The table of projected changes in precipitation for June-August have been updated (specifically for RCP 8.5, 75th percentile). This affects all users who have referred to this table prior to February 12 2016.
