C_fTemp: Intradaily evolution of ambient temperature
Description
From the maximum and minimum daily values of ambient temperature, its evolution its calculated through a combination of cosine functions (ESRA method)Arguments
sol
A Sol object. It may be the result of the
calcSol function. BD
A Meteo object, as provided by the
readBD function. It must
include information about TempMax and TempMin. Value
- A
zoo object with the profile of the ambient temperature.
Details
The ESRA method estimates the dependence of the temperature on the time of the day (given as the local solar time) from only two inputs: minimum and maximum daily
temperatures. It assumes that the temperature daily profile can be
described using three piecewise cosine functions, dividing the day
into three periods: from midnight to sunrise, from sunrise to the time
of peak temperature (3 hours after midday), and to midnight.References
