Annual Harmonic Series Parameter

General Description

A Parameter which returns the value from an annual harmonic series.

This Parameter comprises a series N cosine function with a period of 365 days. The calculation is performed using the Julien day of the year minus 1. This causes a small discontinuity in non-leap years. API Reference

$$f(t)=A+∑n=1NAn⋅cos((2πnt)/365+ϕn)$$

Attributes

Name	Description	Required
mean	Mean value for the series (i.e. the position of zeroth harmonic)	Yes
amplitudes	The amplitudes for the N harmonic cosine functions. Must be the same length as phases	Yes
phases	The phase shift of the N harmonic cosine functions. Must be the same length as amplitudes	Yes
