Short summary
As numerous high-resolution historical gridded climate datasets are available in Alberta, many previous works have simply combined multiple climate datasets without pre-assessment, which may cause unreliable outputs. This study suggested a systematic climate data evaluation system and generated a new performance-based climate dataset. This study proved that the new dataset is a better representation of historical climate conditions, enhancing hydrologic simulations.
