...
- The time between two local minima (lows) should be at least 2700 seconds or 45 minutes.
- Only the last three lows before T0 and the first four lows after T0 are considered.
- The first two lows of the last three lows just before T0 are skipped, leaving only the third last one.
- Similarly the first two lows just after T0 are skipped, leaving the third and fourth ones.
forecastLoopSearchPeriod
When a forecastLoopSearchPeriod is configured the transformation will be repeated for each external forecast found in the defined period.
This will only work when the <inputVariable> and <outputVariable> are external forecasts, the output variable for each execution will get the same external forecast time.
