Note: Interpolated weather data is provided by Alberta Agriculture and Forestry. The data for each township location was estimated using a mathematical data interpolation procedure that weighted up to the 8 nearest station observations. Details in the interpolation methodology can be found in this document . Please be aware that the data is subject to change under further review.
