The Daily 10 km Gridded Historial Climate Dataset for Canada 1961-2003 (ANUSPLIN Point Grid) contains gridded point locations of daily maximum temperature (°C), minimum temperature (°C), and precipitation (mm) for the Canadian landmass south of 60°N . Each daily grid contains interpolated point estimates arranged in a regular grid with a spacing of 10 km. Grids were interpolated from daily Environment Canada climate station observations using a thin plate smoothing spline surface fitting method implemented by ANUSPLIN V4.3.

The data are georeferenced TIF images, one image for each day of the year.

Spatial reference and data type

These data sets are available in Geographic Coordinate System, Horizontal Datum: North American Datum (NAD) 83. Map projection name: Albers Conical Equal Area. Other data formats can be accommodated, as the Map Library has access to a number of conversion utilities.

Data access

In order to access these data sets, please visit the Geospatial Centre during reference hours or Library reference staff are available to provide further information about these data sets. Under the terms of the library's license agreement, these data sets are for use by students, faculty, and staff at the University of Waterloo only.

Data manipulation

There are public workstations in the Geospatial Centre that provide access to Geographic Information System (GIS) software, program extensions and data manipulation utilities. Patrons may use the GIS software in the library to view and manipulate the data. UWaterloo faculty, students and staff may copy these data to other media.
