Short summary

As climate changes, the need for easily accessible high resolution and unbiased projections of snow cover indices to develop adaptation plans increases. We produced such dataset for eastern Canada and made it publicly available. The analysis of the snow cover projection in Quebec up to the year 2100 revealed the following changes: a shortening of the snow season; a decrease of the maximum snow amount in the south and an increase in the north; more interruptions of the snow season in the south.
