ANUSPLIN Gridded Climate Dataset

The ANUSPLIN Gridded Climate Dataset for Canada is a station based interpolated dataset produced using the Australian National University Spline (ANUSPLIN) model. It is produced by Agriculture and Agri-Food Canada and covers all of Canada. The dataset is available from 1950-2015 at daily and monthly timesteps for maximum temperature, minimum temperature, and total precipitation at 10km (0.1 degree) resolution. The ANUSPLIN Gridded Climate Dataset for Canada is a comprehensive and station-based interpolated dataset that has been meticulously produced using the Australian National University Spline (ANUSPLIN) model. Created by Agriculture and Agri-Food Canada, this dataset encompasses the entire geographical expanse of Canada and offers a valuable resource for researchers and climate enthusiasts alike.

Researchers and users interested in accessing the dataset can find it through the following external links: - Daily Data: ANUSPLIN Gridded Climate Dataset for Canada (Daily) - Monthly Data: ANUSPLIN Gridded Climate Dataset for Canada (Monthly)

It provides a detailed view of climate conditions with data available from 1950 to 2015, offering insights into daily and monthly variations in maximum temperature, minimum temperature, and total precipitation. This dataset offers a valuable resource for climate research, environmental studies, and various applications that require historical climate data for Canada and parts of the United States. Researchers can explore climate trends, assess climate change impacts, and derive valuable insights into the region's climate patterns using this comprehensive dataset.
