Detailed Description
A class implementing a temperature-index (positive degree-day) scheme to compute melt and runoff, and thus surface mass balance, from precipitation and air temperature.
Temperature-index schemes are far from perfect as a way of modeling surface mass balance on ice sheets which experience surface melt, but they are known to have reasonable data requirements and to do a good job when tuned appropriately [Hock05].
