Description
The homogenisation tool used at ZAMG for daily data is called HOMOP. It combines PRODIGE for break detection with SPLIDHOM and INTERP for break correction. Only break detection was used in this work.
In HOMOP three different penalty criteria are used for PRODIGE. The methods of Caussinus and Lyazrhi (1997), Jong et al (2003) and Lebarbier (2005). Addionally breaks are detected in different seasons: summer, winter, summer and winter half years and the annual data.
Usually those different results are combined leading to the definition of a break as the following: at least two methods have to find the breaks in more than 50% of the reference stations in at least two of the time series.
The presentation will give a short insight into the method.
