Canadian Gridded Homogenized Surface Air Temperature – Version 3.1 (CanGridT V3.1) CanGridT V3.1 provides high-resolution gridded surface air temperature data for Canada (Wang et al., 2026), derived from homogenized station observations (Vincent et al., 2020). These datasets support climate analysis, trend assessment, and applications such as model validation, downscaling studies, and climate monitoring. CanGridT consists of six gridded temperature datasets: Dataset Name Description CanGridT mly Monthly average daily mean temperatures CanGridTmin mly Monthly average daily minimum temperatures CanGridTmax mly Monthly average daily maximum temperatures CanGridT dly Daily mean temperatures CanGridTmin dly Daily minimum temperatures CanGridTmax dly Daily maximum temperatures Daily mean temperature is calculated as the average of the daily maximum and minimum temperatures. All datasets were produced using a gridding method (Abbasnezhadi & Wang, 2024) based on ordinary kriging applied separately to: • station climate normals (1961–1990) • station climate anomalies relative to the normals The gridded normals and anomalies are then combined to obtain final gridded temperature values…
