The project’s overall objectives were to:
• develop quality control and homogeneity assessment procedures as input for the classification
• develop a novel classification scheme for ranking the series and stations
• identify the most valuable (i.e. high quality, homogeneous, long, complete) series of the SPN
The following objectives were achieved:
• A quality control procedure tailored to the SPN was developed and applied to all series. As a result each single observation has a (boolean) flag assigned.
• A novel break detection method was designed for phenological series.
• A novel classification scheme was developed in order to identify the most valuable Swiss phenological stations and series. The main input for the classification resulted from the quality control and the break detection, also information such as the length and completeness of each series were used as input for the classification.
• An R – package was produced containing the break detection and the classification.
The project finished in summer 2018. The final report is now available, published in the MeteoSwiss Technical Report Series. A paper describing the main findings is in preparation.
