TMU 2.1 Released, November 2004

The focus of this release was on enhancing the TCHP product, based on feedback gathered during the summer 2003 evaluation. Enhancements to the TCHP looping product included:
  • Convective SIGMET forecast product loop
  • 2-hour Collaborative Convective Forecast Product (CCFP) product loop
  • Center Weather Advisory (CWA) product loop
Crosswind Decision Aid

Crosswind DFW Decision Aid. The color key at left explains the meaning of each color and changes according to runway conditions (DRY, WET, IFR, etc...).

Updates to the static displays of the TCHP product included:
  • 2-hour CCFP products
  • 4-hour CCFP products
  • 6-hour CCFP products
The FX-Collaborate system that is used by the forecasters at the Dallas/ Forth Worth CWSU was also updated to handle the above product suite.

The TMU Website was updated to include a crosswind product developed by the CWSU Forecast Team and placeholders for future products (icing, turbulence, and ceiling and visibility).

Re-designed user interface

Updated TMU interface for accessing Decision Aids and Hazard Products. Also includes placeholders for future Decision Aids and Hazard Products.

Roll-over reveals product availability

Access NOAA, October 2004: "The Aviation Meteorology Award was presented to Thomas Amis, James Ott, Doug Reno and Charles Hays of the NWS Center Weather Service Unit in Fort Worth, Texas; and, Lynn Sherretz, Greg Pratt, Dennis Rodgers, Jim Frimel, Young Chun, Lisa Gifford, Chris Masters, and Doug Ohlhorst of the Aviation Section, NOAA Forecast Systems Laboratory in Boulder, Colo. They are being recognized for their outstanding daily efforts to enhance and develop new methods of displaying weather information for the aviation community...."

According to the award citation, "....The close working relationship between the Fort Worth ARTCC, the CWSU, and FSL has resulted in outstanding public relations for all agencies concerned. The customers have been the ultimate recipients of better and improved services. The benefits this team brings to the FAA Fort Worth ARTCC have been far reaching, and are paying significant dividends to the safety of flight and the efficient use of the nation's airspace system, with fiscal savings to commercial and general aviation."

TMU Spring 2003 Release

The team demonstrated and evaluated the initial version of the Tactical Convective Hazard Product (TCHP) on the Traffic Management Unit (TMU) Web site ( to the Dallas/Fort Worth Traffic Managers. The WEB site was enhanced based on feed back from the Traffic Managers from static displays of the TCHP to allow the Traffic Manager user to toggle on/off map backgrounds and convective products that comprise the TCHP. The convective SIGMET portion of the TCHP was enhanced to include convective SIGMET nowcast, convective SIGMET forecast, and convective SIGMET text. The convective SIGMET forecast is created by advecting the convective SIGMET nowcast using the motion information so that it is time matched with the National Convective Weather Forecast. A new impacted jet route map background was created using the convective products that comprise the TCHP for color-coding jet route segments. Testing, Training, and evaluation plans have been created and added to the web site. The following convective products and map backgrounds make up the TCHP:

  • Convective SIGMET Nowcast
  • Convective SIGMET Forecast
  • Convective SIGMET Text
  • National Convective Weather Forecast
  • National Convective Detection Product
  • National Convective Detection Motion Vectors and Cloud heights
  • VOR (VHF Omnidirectional Range) maps
  • Jet Route maps
  • DFW TRACON scale and map background
  • ZFW ARTCC scale
  • IAH TRACON scale and map background
  • ZHU ARTCC scale
  • Impacted Jet Routes
