Accumulative

disaggregates data by dividing the values

Input
  • InputVariable
Output
  • OutputVariable
Description

This transformation performs a disaggregation on an accumulative input time series. Divides the values of the input time-series by the number of time-steps in the output time-series and stores the resulting values at each step.

The table below shows how daily values are disaggregated to 6-hourly values using this method.
