R: Intradaily evolution of ambient temperature

C_fTemp {solaR}

R Documentation

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.
