Data monitors

A data monitor is a process that runs one or more decoders. After the data is stored in the raw text or spool files, data monitors process the raw data into McIDAS files such as surface hourly observations, synoptic reports, upper air reports, and grid files.

The following table lists the supported McIDAS-XCD data monitors.

To make the data monitors more flexible, each is designed to use a text formatted configuration file similar to those used for circuit configuration. This configuration file contains the .IDX files to search, WMO headers to decode, decoder display number, MD file numbers to store data, etc.

Figure 2 shows an example of the configuration script file for the GFS MOS decoder.
