GOES Channel Data

The GOES Channel Data can be processed in either GINI format or in McIDAS area format, but not both at the same time.

In all SDIs, data and spool files are written to the data path defined in the file /etc/init.d/ingcntl. When SSEC ships a GINI SDI system, the data path defaults to /data. When NOAAPORT two-card systems are shipped, the GINI data path defaults to ~mcadde/mcidas/data and the NCEP/NWSTG format files are written to /data.

The following sections contain information specific to their data type:

GINI Format

To save the GOES channel data in GINI format, indicate the abbreviated WMO header (TTAAii) of the product and the number of files to retain of each in the file /opt/nport/retain.nport. Each WMO header and its number of files to be retained should appear on a separate line. For example, to keep the last 10 copies of product TGIE01, add the following line to /opt/nport/retain.nport.

TGIE01 10

The following conventions also apply to GINI format data:

Area Format

To process GINI data into McIDAS area format, create files named area.<wmocode> in the /opt/nport directory. Each file's content must consist of the three numbers listed below.

starting_area_number   ending_area_number   current_area_number

For example, if you create the file /opt/nport/area.TGIE01 with the contents 2000 2099 2000, the area files for product TGIE01 would cycle through area numbers 2000-2099. Note: When initially creating these area.<wmocode> files, enter the same value for starting_area_number and current_area_number. The current_area_number will automatically be incremented by the ingestor.

Also verify that the line in the file /etc/inet.d/ingcntl that defines the data path to write to reads cd ~mcadde/mcidas/data.

The following conventions also apply:

Accessing the Data via ADDE

Once the SDI begins to ingest data and is connected to the network, the data can be accessed on workstations running McIDAS via ADDE. The ADDE group name, by default, is GINI. Perform the Changing Server Dataset Names procedurefollowing this section if you want to change it.

Perform these steps to access the SDI's data.

1. From a McIDAS workstation:


For example, if the SDI has an IP address of


2. Use the ADDE command named DSINFO to list the descriptor names.


The output should look similar to that below.:

DSINFO -- done

At this point the suite of ADDE commands can be used with the data.

Changing Server Dataset Names

Perform the following procedure to change or update GINI server dataset names.

1. From the console, login as user mcadde or telnet into the ingestor as user mcadde.

2. To change ADDE names associated with particular datasets, edit the file ~mcadde/mcidas/data/RESOLV.SRV. The following is an example listing of this file. Notice that all fields are comma delimited. You can not place a comma in the comment field.

N1=GINI,N2=TIGE05,TYPE=IMAGE,K=AREA,R1=501,R2=599,C=Conus band 5,
N1=GINI,N2=TIGF01,TYPE=IMAGE,K=AREA,R1=601,R2=699,C=NH visible,
N1=GINI,N2=TIGF02,TYPE=IMAGE,K=AREA,R1=701,R2=799,C=NH band 2,
N1=GINI,N2=TIGF03,TYPE=IMAGE,K=AREA,R1=801,R2=899,C=NH band 3,



is the ADDE group name



is the ADDE descriptor name (for clarity, we recommend that its value match the wmocode in the corresponding /opt/nport/area.<wmocode> file)



is the data type



is the data format or kind



is the beginning dataset position number (must match the first number in the sequence of numbers in in the corresponding /opt/nport/area.<wmocode> file)



is the ending dataset position number (must match the second number in the sequence of numbers in the corresponding /opt/nport/area.<wmocode> file)



is the comment field displayed with DSINFO
