You cannot use Modifiers to edit changes to reservoir parameters.

The list of modifiers is a configurable option. Unless a modifier is on the list, you are not able to use it.

Contact the Configuration Focal Point at your office if you would like a modifier added.

The modifiers tab tracks when a modifier was created. Click on a workflow in the top box of the Forecast Management tab and view the modifier currently in use for the segment.

Editing tabular data in Modifiers uses the same procedure as it is in Plots.

You are limited to using the edit by clicking option when editing graphical data. Tabular editing is also an available option.

Modifiers are saved when you click "Apply" or "Apply to".

You have the option of manually deleting modifiers you no longer need.

Otherwise, the modifiers you create remain in the list until deleted by a Rolling Barrel task.

The CHPS System Manager at your offices defines the Rolling Barrel behavior.

Return to the plots described in Lesson 3.2 and view the results of the edits. The plot refreshes automatically.

Once you are satisfied with the edits, upload the changes to the Central Server using the Configuration Manager. Other users download the files to their system.

You also have the option of exporting the calibration parameters. Export the data in any of the formats available for other CHPS time series, such as Pi-Service, XML, and netCDF.
