Time Series Analysis

Lecturers: Thomas Laepple

Content:

Time series, a sequence of observations given at a sequence of time points, are ubiquitous in geosciences. Two main branches of time series analysis exist. Methodologies applied in the time domain and frequency domain analysis tools (‘spectral analysis’). In this course you will learn the basic concepts of time series analysis using both complementary approaches. A special focus is on the application of these methods to geological or climate related datasets also discussing pitfalls and caveats.


Competences:

At the end of this course you are able to understand the basics and apply linear time-series modelling, spectral analysis and the exploratory analysis of time-series using tools in the time and frequency domain. You will be able to perform these analyses using the statistical software R and to better judge published results involving time-series analysis.

Assessment:

The exam will be an homework assignment applying the methods learned on individual datasets and delivering a report
and the code.
