How to Ingest and Display GOES Satellite Data into GEMPAK

How to Ingest and Display GOES Satellite Data into GEMPAK

  • GEMPAK can display GOES Satellite Data
  • GEMPAK can display both AREA and GINI formatted satellite data.

    How to set up your GEMPAK LDM configuration files

  • The GEMPAK distribution includes a template script that will have the most current actions included. To see more information regarding this process vistit the GEMPAK documentation about this topic.
  • The information below is only an example of how the ldmd.conf and pqact.conf files may look. Your paths and actions may differ, but the information below should give a general idea on the process as well as descriptions and explanations of some of the terms.

    ldmd.conf

  • How to request GOES data via the LDM
  • ldmd.conf example entry:

    ########################################
    # Request Entries
    ########################################
    #
    # LDM servers request data from Data Sources
    #
    # (request) (feedset|feedset) (pattern) (hostname pattern)

    request      UNIWISC|NIMAGE      ".*"     idd.unidata.ucar.edu
    [sample host pattern, yours may differ]

  • For more information regarding the UNIWISC (or NIMAGE) feed and other feedtypes, please visit: Feedtypes
  • UNIWISC GOES data and products are delivered as AREA files and the NIMAGE feed carries data and products as GINI files

    pqact.conf

  • How to "act" on the data once it is on disk in the LDM queue
  • Reminder..ALL spaces in the pqact.conf file need to be (tabs)!
  • pqact.conf example entries:
