Hola
Ya hace tiempo que le doy vueltas a esos paramentros que salen en los datos NOAA y no se muy bien que significan.
Alguien lo puede explicar?
Gracias

Se usan para calculo de calefaccion y refrigeracion, no tengo el weatherlink aqui pero creo que a partir de una media standar de 18.3 grados el heat dice los grados que han faltado para la media (calefaccion a activar) y el cool lo mismo pero para enfriar (aire acondicionado)

Pues no eran 18.3º, eran 18º .
Garil también tiene razón, he sacado un copiado de lo que dice davis de los parámetros, tampoco es que se suelten mucho explicando las cosas.
Data: Heating & Cooling Degree-Days
Although degree-days are most commonly used in agriculture, they are also useful in building design and construction, and in fuel use evaluation. The construction industry uses heating degree-days to calculate the amount of heat necessary to keep a building, be it a house or a skyscraper, comfortable for occupation. Likewise, cooling degree-days are used to estimate the amount of heat that must be removed (through air-conditioning) to keep a structure comfortable. Just like growing degree-days, heating and cooling degree-days are based on departures from a base temperature. 65º F is almost always used as this base.
One heating degree–day is the amount of heat required to keep a structure at 65 ºF when the outside temperature remains one degree below the 65 ºF threshold for 24 hours. One heating degree–day is also the amount of heat required to keep that structure at 65 ºF when the temperature remains 24°F below that 65º threshold for 1 hour.
Likewise, one cooling degree–day is the amount of cooling required to keep a structure at 65 ºF when the outside temperature remains one degree above the 65 ºF threshold for 24 hours. One cooling degree–day is also the amount of cooling required to keep that structure at 65 ºF when the temperature remains 24°F above that 65º threshold for 1 hour.
Depending on the calculation method, both heating and cooling degree-days can accumulate in the same day. Also, note that there are no negative degree-days. If the temperature remains below the threshold, there is no degree-day accumulation.
Heating and Cooling degree-days may be calculated by either the High/Low method or the Integration method.
Note: The Heating and Cooling degree-days displayed in the Strip Chart, Plot, and Browser use the intregrated calculation method with a 65°F (18°C) base.
Below are some representative heating and cooling degree-day totals from different parts of the United States.

Ya puestos y viendo que el tema el flexible yo lo voy a usar para calcular el día que me puedo poner los pantalones cortos.

Entonces en el WWS hay que cambiar los parametros que estas en settigs, advanced parameter settings??
lo digo por que alli pone heating treshold 65 y temperature abobe treshold 65.
Si nosotros trabajamos en º C tendriamos que cambiar esto por el 18 no?
