Description
This transformation is used to sample a timeseries of several years into members of an ensemble, each year being copied to another ensemble members. The start year within the input value has to be specified, the month and day the year begins can be specified in startWaterYear. Output variable should be of the same type as input variable. This transformation is mainly used to create climatological ensembles.
Configuration
A basic configuration of the function is described below.
