History of Project Updates

August 21, 2012 - Update to a higher resolution map database

The TCGP plotting system has been updated to use a newer, higher resolution map database. For those who like details, maps now use the "Earth..4" map database in NCAR Command Language (NCL). The previous map database ("Earth..1") did not include the island of Barbados, as well as some of the U.S. and British Virgin Islands, the Cayman Islands, and many other small islands. The new map database will also allow the state boundaries of Mexico, Brazil, Canada, and several other countries to be included. The outlines of U.S. counties will now be displayed whenever the range of the map domain is smaller than 30 degrees.

Example of the old map database.

Example of a plot using the old map database. The coastline is coarse and several significant islands, such as Barbados and Grand Cayman, do not appear.

Example of the new map database.

Example of a plot using the new map database. The coastline has much more detail and the map now displays the islands of Barbados, more of the British and U.S. Virgin Islands, the Cayman Islands, and many other smaller islands.

September 20, 2011 - New server for TCGP

The TCGP moves to a new server today. We expect the transition to be seamless to the users if they are using the http://www.ral.ucar.edu/hurricanes/ entry point. If you were previously using http://verif.rap.ucar.edu/guidance/ then please update your links. If you are still having trouble, please let us know.


August 14, 2011 - Phase I released   

Phase I of the Tropical Cyclone Guidance Project (TCGP) was released today.  In this initial release, the repository includes all available track and intensity forecasts in the National Hurricane Center's public ATCF a-decks as well as the developmental tracker results from the UK Met Office global model. This release also features four types of real-time guidance plots for the North Atlantic, Northeast Pacific, and Central Pacific basins.

These plot types are:

Phase I also implements a global overview map of current tropical cyclone activity with links to individual storm pages. Various text data files are also linked from each storm's individual storm pages. To find out more about our plans for future phases of this site's development, click here
