CANADA HDD METADATA

The aim of this study is to present spatial models of heating degree days (HDD) for Canada for two thirty-year periods, 1951-1980 and 1981-2010, 
using daily temperature gauge observations over these time periods.  Stations with ≤ 10 missing days in a year and ≥ 10 years over each 
thirty-year period were included, resulting in 1339 and 1679 stations for the 1951-1980 and 1981-2010 periods, respectively.  
Mean absolute error (MAE) of the models ranged from 124.15°C for the 1951-1980 model (2.7% of the surface mean) to 137.60°C for the 
1981-2010 model (2.4%).  This note presents a difference map comparing the two models, as well as maps of model standard errors.  
The available grids for 1951-1980 and 1981-2010 are available at ~2km resolutions as well as csv files of HDD estimates at Canadian communities.
