Analysis and Interpretation: Homogenization of Instrumental Data

  • Ingeborg Auer


To explore past climates and to analyze variability and change, historical climatologists make use of instrumental measurements that pre-date our modern, standardized equipment and measurement practices. But are long-term instrumental series always reliable? And when can we trust the displayed trends? This chapter introduces methods for the homogenization of early instrumental data, an essential procedure to detect non-climatological breaks or trends in a series and remove them as best as possible.
