Table 1 Individual and compound climate scenarios considered for addressing the nonlinear response of FT characteristics to individual and compound changes in temperature and snow depth conditions across Québec and at the grid scale.

From: Compound changes in temperature and snow depth lead to asymmetric and nonlinear responses in landscape freeze–thaw

Scenario description
