Remarks

IDMON monitors the status of stations and generates lists to inform operations of new stations and stations that stopped reporting. With this information, operations can remove or add data to the station database (STNDB.CORE).

To activate or deactivate station ID monitoring, edit the appropriate decoder configuration file. Decoders developed at SSEC create two station files: OLDtype.IDM and NEWtype.IDM where type is one of the following data types.

Data type	Decoder
ISFC	SAO/METAR
IRAB	upper air
SYN	synoptic
PIRP	pilot report
TERM	terminal forecast
GFS	GFSMOS
NAM	NAMMOS

File OLDtype.IDM contains a record of all stations that are reporting data and are included in the master table of stations in the decoder's MD file.

File NEWtype.IDM contains all stations reporting data, but are not included in the master table of stations in the decoder's MD file.

To add new stations reporting data or delete stations no longer reporting, use command UPDIDS. SSEC recommends updating station files monthly for locally developed decoders. If you update your own master ID table, please document the changes and notify SSEC.

SSEC sends updated ID files with each McIDAS upgrade.
