A “degree day” indicates that the daily average outdoor temperature was one degree higher or lower than some comfortable baseline temperature (in this case, 65°F—a typical baseline used by the National Oceanic and Atmospheric Administration [NOAA]) on a particular day. Aviation Weather The National Climatic Data Center (NCDC) is the world's largest active archive of weather data. Without degree days, comparing the energy used over two periods would be analogous to calculating the miles per gallon rating for your car without knowing how far you had driven. NCDC produces numerous climate publications and responds to data requests from all over the world. Three-month and precip maps are not available in Contour format, and therefore, no Three-month Degree Day maps are available. Please Contact Us. For example, if the average temperature on a particular day is 78°F, then that day counts as 13 cooling degree days, as a building's interior would need to be cooled by 13°F to reach 65°F. The archives were reconstructed for heating degree days back to July 2002 and for cooling degree days back to January 2003. Products are: Sea Surface Temperature (SST), SST Anomaly, Coral Bleaching HotSpot, Coral Bleaching Degree Heating Week, Bleaching Alert Area, and the Virtual Stations.

We will now look at Seasonal Heating Degree Days (HDD), which is the sum of temperature differences of ALL days - rather than just 1 day or 1 week - during which heating is required. Find a broker. The higher HDD indicates a higher heat loss and therefore, higher fuel requirements. Divisional degree day values are computed from climate division monthly temperatures using a statistical algorithm. Conversely, if the average outdoor temperature is 34°F, then that day counts as 31 heating degree days, as a building's interior would need to be warmed by 31°F to reach 65°F.

The calculations shown in the two examples above are performed for each day of the year and the daily degree days are accumulated so that we can compare months and seasons. Earlier in this tutorial, you learned that corals are sensitive to temperatures warmer than the bleaching threshold, i.e., 1°C above the highest summertime mean SST.You also learned that Coral Reef Watch's (CRW) 50km Coral Bleaching HotSpot product provides a snapshot of where corals are stressed right now around the globe from heat stress. I called the repair people immediately and they discovered a stuck thermostat! Daily temperature values for each region of the United States are used to calculate departures from the 65°F baseline. If the average outside temperature for a day is 1 degree less than the inside temperature, then you would accumulate 1 degree day on that day. Degree days are based on the assumption that when the outside temperature is 65°F, we don't need heating or cooling to be comfortable. “Warmer” colors indicate an increase in temperatures between the two periods, leading to less of a need to turn on the heat—that is, fewer heating degree days. Government Internet Service Home page. Education/Outreach NOAA Center for Weather and Climate Prediction. The annual population-weighted heating degree days (HDD) decreased by 6 % between the periods 1950–1980 and 1981–2017; the decrease during the period 1981–2017 was on average 6.5 HDDs per year.
