Detailed Description

Generate daily variations around a single daily average.

The parameter to be interpolated is assumed to be a daily average and a sinusoidal variation of the data will be generated around this average.

Either one or two additional parameters bearing the same name followed by "_MIN" and/or "_MAX" are provided or a fixed amplitude is provided as argument (it will also be used as a fallback if the _MIN and _MAX parameters are missing at some timesteps). Iit is also possible to provide the "phase" or the fraction of the day when the minimum is reached.

[Interpolations1D]
TA::resample         = daily_avg
TA::daily_avg::range = 5
TA::daily_avg::phase = .25                ;assume that TA varies +/- 5K around its average during the day and reaches its minimum at 6am

Note: If both the average (the parameter itself in the data set), min and max are provided, an error message will be returned.
