Degree days are a measure of heat accumulation. These data have long been used to estimate energy requirements for heating and cooling buildings. In recent years agricultural scientists have used accumulated degree days to estimate crop development over time.
For design purposes, so-called “normal” degree day products can be used. These static averages can help a building designer determine the type of heating, cooling and insulation systems required for a building.
For modeling energy use or crop development over time, however, a time-series of degree day data are required. And for calibrating models, an historical archive of time-series data is necessary.
Hydrosphere provides both heating and cooling degree days calculated against a base temperature of 65 degrees Fahrenheit. Unlike many degree day products, we provide a time-series database calculated on a daily basis. Daily values of degree days can be used by energy companies to manage stockpiles and deliveries, to assist in dispatching resources and to assist in marketing.
Hydrosphere’s standard degree day publication is based on the NCDC Summary of the Day daily maximum and minimum temperatures and is calculated using the same techniques as NOAA. Please inquire about custom publications using other base temperatures or other algorithms.
