Running Zdrcal as an IRIS Exec Task

Running Zdrcal as part of the standard scheduler allows the ZDR calibration status to be routinely monitored without operator interaction.

When Zdrcal is added the IRIS Task Scheduler as an Exec Task, it runs routinely either at regularly scheduled times, or it can be set to run at specified weather events, in which a IRIS mode switch is triggered by WARN products.

Figure 1. Zdrcal Exec Task
To run Zdrcal as an IRIS Exec task, type: 
zdrcal –auto 2 > &1 | signal_iris
-auto
Sends the progress report output to a terminal. The utility performs the data acquisition and analysis part in –auto mode, that is the calibration status is monitored, not updated.
2 > &1 | signal_iris
Reroute the utility warnings to IRIS message log and popup, including the warning issued if the calibration offset drifts beyond the specified alarm threshold.
