Short summary
Short summary
We assessed the sensitivity of a simple permafrost model to changes in parameter values using measured data across northern Canada. We altered the value of one parameter at a time to assess the changes in the resulting temperature. The model was most sensitive to changes in the freezing season parameters and least sensitive to changes in the thawing parameters. However, the importance of specific parameters varied across Canada. The findings of this study can aid in development of future models.

Short summary
Short summary
Snow cover is critical to everyday life for people around the globe. Regular measurements of snow cover usually occur only in larger communities because snow monitoring equipment is costly. In this study, we developed a new low-cost method for estimating snow depth and tested it continuously for 1 year at six remote field locations in coastal Labrador, Canada. Field testing suggests that this new method provides a promising option for researchers in need of a low-cost snow measurement system.

Short summary
Peatland permafrost in northeastern Canada has been misrepresented by models, leading to significant underestimates of peatland permafrost and permafrost distribution along the Labrador Sea coastline. Our multi-stage, multi-mapper, consensus-based inventorying process, supported by field- and imagery-based validation efforts, identifies peatland permafrost complexes all along the coast. The highest density of complexes is found to the south of the current sporadic discontinuous permafrost limit.
