- accumulative observations:
- Equidistant time series: The observation is the integral of the continuous process in the time interval t, t + Dt, like for example rainfall amounts. Accumulative observations produce volumes rather than intensities. For example, runoff expressed in mm is accumulative, whereas runoff expressed in m^3^ m3/s is instantaneous
- Non-equidistant time series: accumulative observations are not valid.
- average observations:
- Equidistant time series: computed quantities, obtained e.g. by aggregation of instantaneous observations over a larger time interval. Average observations are treated in hymosas instantaneous observations since in common mathematical operations they are equivalent. (From a view-point of information content they are, however, different: by averaging, information about the process is lost!)
- Non-equidistant time series: average observations are not valid, and
