Tanker spilling oil.

GNOME (General NOAA Operational Modeling Environment) is the oil spill trajectory model used by OR&R Emergency Response Division (ERD) responders during an oil spill. ERD trajectory modelers use GNOME in Diagnostic Mode to set up custom scenarios quickly. In Standard Mode, anyone can use GNOME (with a Location File) to:

  • predict how wind, currents, and other processes might move and spread oil spilled on the water.

  • learn how predicted oil trajectories are affected by inexactness ("uncertainty") in current and wind observations and forecasts.

  • see how spilled oil is predicted to change chemically and physically ("weather") during the time that it remains on the water surface.

To use GNOME, you describe a spill scenario by entering information into the program; GNOME then creates and displays an oil spill "movie" showing the predicted trajectory of the oil spilled in your scenario. Along with GNOME, most users also will want to download the Location Files for their regions of interest. Location Files contain prepackaged tide and current data and make it easier to work with GNOME.

GNOME was developed by the Emergency Response Division (ERD) of NOAA's Office of Response and Restoration (OR&R). The latest version is GNOME 1.3.3.

More Information about GNOME

This section includes the following information, also available through the navigation links at the top of each page.
  • GNOME Location Files and Associated Resources Files you can use to model spill scenarios set in particular areas (such as Prince William Sound, Alaska, or Long Island Sound, New York) and example problems you can work to build your understanding of GNOME.
  • GNOME Toolkit Tools for displaying GNOME trajectories in ArcView 3.x and ArcMap 9.x. Learn about and subscribe to the GNOME Listserver.
  • Frequently Asked Questions About GNOME Answers to frequently-asked questions (FAQs) about GNOME, including getting Location Files, and using GNOME's Diagnostic Mode to create Diagnostic Save Files.
  • The GNOME Wizard Direct comments or questions about GNOME to the GNOME Wizard.
