Transformation: | SumInterval |
|---|---|
Transformation Group: | Accumulation |
Description: | This transformation creates cumulative curves from the input time series within several intervals. The intervals are defined by the specified intervalTimeStep. For a given interval the first output value equals the first input value within the interval and the other output values are equal to the sum of the corresponding input value and all previous input values within the interval. The startTime of an interval is exclusive and the endTime of an interval is inclusive. The output time series must have the same timeStep as the input time series. In case the transformation is from instantaneous/mean to accumulated, the result is multiplied by the timestep. |
Hydrological Information
Purpose and use of Transformation: | To create cumulative curves in several intervals. |

Background and Exceptions: | Does This transformation also works for grid input and output. It does not work for irregular timeStepstime steps. If the transformation is from instantaneous/mean input parameter type to accumulated output parameter type, then the result is multiplied by the timestep in seconds. In this case the input data is assumed to be in units/second. |
