   What is spectral analysis?

   • Spectral analysis is a method of transforming sequenced data to extract or filter information. It is frequently used as a preliminary step to simplify further processing. While spectral analysis was initially developed using time series data, it can also be applied to any sequence of data with at least one independent variable.

   What is spectral analysis in geoscience?

   • It is frequently used as a preliminary step to simplify further processing. While spectral analysis was initially developed using time series data, it can also be applied to any sequence of data with at least one independent variable. In geoscience this variable is typically distance or depth.

   What type of data is processed by spectral analysis?

   • The signal or data processed by spectral analysis can be either one-dimensional, such as data from a seismograph, or multidimensional, such as seismic reflection surveys (Bath 1974; Buttkus 2000; Jekeli 2017; Stoica and Moses 2005 ).

   How spectral analysis is used in climate science?

   • In climate science, spectral analysis can be used to determine short and long term variations from noisy data. For example, a Fourier transformation into the frequency domain can be used to identify cyclical patterns in a climate system (Mudelsee 2010; Rao and Hsu 2008 ).

   Is spectral analysis a time series?

   • Spectral analysis is part of time series analysis, so the natural place to start our discussion is with the notion of a time series. The quip (attributed to R. A. Fisher) that a time series is ‘one damned thing after another’ is not far from the truth: loosely speaking, a time series is a set of observations made sequentially in time.

   How does spectrum analysis work?

   • Spectrum analysis applies across many factions of engineering. For example, engineers must check cellular radio systems for harmonics of the carrier signal in order to prevent interference between systems at the same frequencies. Distortion of the message modulated onto a carrier also requires spectrum analysis, shown in Figure 2.
