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)

Usage

fTemp(sol, BD)

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.

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.

Value

A zoo object with the profile of the ambient temperature.
