Accurate, but only to a degree

Summary

Discusses whether we need to change the way we calculate degree days. Refers to a paper claiming that the published degree days differed from true degrees measured from hourly temperatures by more than ten degree days for one month in seven. Highlights the errors introduced by the Met Office. States that putting the errors right is very simple, just requiring a return to the pre-1927 formula with updated area and bias coefficients, which have already been calculated. Notes that BRECSU would like to hear the views of energy users on the desirability of suggested changes.
