Spatial variations and long-term trends of potential evaporation in Canada

Assessing the status and trend of potential evaporation (PE) is essential for investigating the climate change impact on the terrestrial water cycle. Despite recent advances, evaluating climate change impacts on PE using pan evaporation (Epan) data in cold regions is hindered by the unavailability of Epan measurements in cold seasons due to the freezing of water and sparse spatial distribution of sites. This study generated long-term PE …
