Then, using the degree days, you could determine "how far you went" during those periods. 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. Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. Satellite Images Heating degree-day figures relates to a "base temperature" and provides a measure of how much (in degrees), and for how long (in days), the outside temperature was below that base temperature.

NOAA Climate.gov portal General mailbox (home page issues, general comments): climate-portal@noaa.gov News & Features: climate-climatewatchmagazine@noaa.gov Typically, heating degree days are calculated as how much colder the mean temperature at a location is than 65°F on a given day.For example, if a location experiences a mean temperature of 55°F on a certain day, there were 10 HDD (Heating Degree Days) that day because 65 - 55 = 10. To calculate the heating and cooling degree-days in the U.S., once we know the daily average temperature for a location, we subtract it from 65˚F. Average temperature maps can wash out days or weeks of hot and cold extremes that are important for things like energy planning and crop risk assessment. The largest decrease occurred in northern Europe and possibly in Italy. 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. Storm Ready Notice: NESDIS has retired and replaced all Coral Reef Watch operational 50km resolution satellite coral bleaching heat stress monitoring products, with products at 5km resolution.
