The authors used the incorrect base elevation in the MLR_WP_WY DET1 equation in Table 8 of the original publication. The equation was printed correctly in Table 3 and applied correctly throughout the analysis in this paper. The authors wish to thank Hafiz Ahmad from Environment and Climate Change Canada for finding this error. The correct Table 8 is provided herein.
