Detrending and deseasonalizing data with fourier series

This is Part 3 of a multi-part series on Pricing Weather Derivatives. In this video we take Daily Average Temperature (DAT) series from Sydney Observatory Hill starting from 1-Jan 1859 and attempt to de-trend and remove seasonal variation using fourier series. In timeseries this is also known as time series decomposition, where the terms are detrending and deseasonalizing data. The denoised temperature time series reveals that temperatures have somewhat uniform peaks. This implies that we could use a first order fourier series model to estimate the seasonal variation in Daily Average Temperature. For parameter estimation of the first order fourier series model, here we use xscipy.optimize.curve_fit which implements the Levenberg-Marquardt algorithm (LMA). This is a method of non-linear least squares and combines both the Gauss-Newton algorithm (GNA) and gradient descent methods. Online written tutorial: https://quantpy.com.au/weather-deriva... In this series we take a deep dive into a type of exotic financial products weather derivatives. Weather derivatives are financial instruments that can be used to reduce risk associated with adverse weather conditions like temperature, rainfall, frost, snow, and wind speeds.
