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.

Monitor	Index	Data type	Decoded Data location	Configuration file
DMBIN		GRIB1, GRIB2 and BUFR	Native GRIB1, GRIB2 and BUFR	GRBFILER.CFG
DMGRID		GRIB1	Grid files	GRIBDEC.CFG
DMNEXR		Radar products	Compressed data files	NEXRFILE.CFG
DMMISC	FO	NAMMOS	MD file NAM	NAMMOS.CFG
	FO	GFSMOS	MD file GFS	GFSMOS.CFG
	FT	Terminal Forecast	Rapid-Access System	TERMDEC.CFG
	SD	MDR	Grid files	MDRDEC.CFG
	TB	TIROS NAV	SYSNAV1	TIRDEC.CFG
	UA	PIREP/AIREP	MD file PIRP	PIRPDEC.CFG
DMRAOB	UJ	TEMP/PILOT	MD file IRAB/IRSG	IRABDEC.CFG
DMSFC	SA	SAO/METAR	MD file ISFC	ISFCDEC.CFG
DMSYN	SM	SYNOPTIC	MD file SYN	SYNDEC.CFG
	SM	SHIP/DRIBU	MD file ISHP	ISHPDEC.CFG

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.
