Degree-Days [PDF]

open access: yes, 2011
The melting of snow and ice is assumed to be related to air temperature as long as air temperature is above a critical threshold, usually close to the melting point of ice. In particular, the amount of snow or ice melted at a certain place, during a certain period, is assumed proportional to the sum of positive temperatures (on the Celsius scale) at ...
