How to Bring the Ingredient Maps to your Office:
What are the Options?



There are a number of options for bringing the ingredients maps to your office:
  1. Run a script to automatically grab the 12Z and 0Z ETA ingredients maps from this web page and port these images into AWIPS. It's much easier than it sounds. Dan Baumgardt, SOO, NWS-WFO LaCrosse, WI is currently using this approach in his office and has generously made a detailed step-by-step explanation on his "Web Image Grabber For AWIPS Netscape" (WIGFAN) website: http://www.crh.noaa.gov/arx/webgrab.htm. This may be the most efficient approach for NWS offices. It involves a few hours of setup time, but it allows NWS forecasters to view the Gempak-generated ingredients maps through the familiar AWIPS interface without having to run the Gempak scripts in the office.

  2. View the ingredients with NTRANS by running an ingredients NTRANS meta file. This allows the flexibility to set the run time to correspond to when data arrives in your office, to adjust the area of the maps, and to apply it to other models. A drawback of this approach is that the NTRANS platform may no longer be in everyday use in many NWS offices.

  3. Run the Gempak scripts locally. This allows the same flexibility described above for NTRANS, but once the scripts are run, the images can be viewed through a local web page or through any image-viewing software such as xanim, xv, QuickTime, etc. A drawback is that this requires the setup of a Gempak script to be run by a crontab and the setup of a virtual x-server on your machine to generate the .gif images. Updated 26 October 2001 to include the most recent ingredients maps.

  4. Access the current 12Z and 0Z ETA Gempak ingredients maps through this web site. This can be slow to download depending on your internet lines and thus is not really practical for everyday operations. A more reasonable option is to download the .fli loops once for each run and store them on your local machine for viewing with QuickTime, xanim, or other software.

  5. Dan Baumgardt's Volume Browser Localization Page has been updated to include new AWIPS Winter Ingredients-based Methodology fields. These fields include EPV* (i.e., PVes, or Saturated Equivalent Potential Vorticity) and QPV. They are combined onto the following AWIPS Ingredient Maps. Many thanks to Phil Schumacher, SOO in Sioux Falls, SD for creating the EPV* field and to Dan Baumgardt, SOO LaCrosse, WI for computing QPV and assembling the diagnostics into these nice plots.

  6. Lastly, you can access the AWIPS pseudo-ingredients procedure files which I put together. This is not recommended for operational use, as the pseudo-ingredients suffer from a number of limitations. See an example pseudo-ingredient AWIPS map.
