We present an integrated data portal and retrieval system for various variable related to hydrology and cryosphere of Québec, named Cold Region Data Accessibility Portal for Québec (CRDAP-QC). The raw data with which this integrated platform is built are pulled from various publicly available data sources. The platform integrates data variables related to climate (maximum, minimum and mean temperature along with total precipitation), snow accumulation (snow cover and depth) as well as Freeze-Thaw characteristics. The platform enables downloading, visualizing, and comparing these data across various temporal (monthly, seasonal and annual) and spatial scales (from 25 × 25 km² grids, to sub-basin and basin, to the whole province). The platform also provides a Printable Document File with summary of the data, an additional set of information on elevation, land-use, and land-cover as well as the location of climate and hydrometric stations within the chosen area. The portal is available in both English and French.
