In the Modeling tab, create a new forecast (Ensemble Compute) with an ensemble forecast run (CWMS Ensemble RAS) as shown in the example below.
When the extract is completed, open the forecast.dss file and you will see the data was extracted for the first ten collection members for each location as expected.
Once a forecast is created, you can set which ensemble traces you would like to run in the forecast (if you would like to only run specific traces). To select the traces to run, click the Select Trace to Compute… button on the Action tab as seen in the figure below. If you do not select specific traces, all ensemble traces will be computed.
The Select Trace to Compute window will then appear. Enter the trace numbers to run in the Ensemble Member field. Leaving the field blank will compute all the ensemble members in the Forecast. Only traces specified in the Forecast Run Editor can be entered. Click Compute to run the ensemble forecast run.
