WRF, ROMS, and SWAN

Model data for WRF, ROMS and SWAN are available through Mapserver. Thanks to Steve Gaffigan for getting the data online before departing AOOS. Thanks to Janene McMahan for digging into the AOOS data management system. More integration to follow with data and formats and general flow of information into AOOS more or less stabilizing.

Snapshot at 2009-07-23 at 6Z with wind speed, surface currents and wave directions plotted using model data produced at 2009-07-23 at 6Z.


Information is available via AOOS's Interactive GIS Mapping Tool. Data layers can be found in the following areas:

Forecast: Regional = AEFF WRF wind forecast, etc
Ocean Forecast: Regional = ROMS, SWAN

The Time and File Time are in the format YYYY-MM-DD-HH and is in GMT time.

The Time is the observation time you would like. The File Time allows you to select a particular model run time you wish to use. If an exact match is not found, the nearest run to that time is then used. This is needed as ROMS, WRF and SWAN all have different initialization times.

For a File Time of 2009-07-23 at 6Z, this selects the following model initialization times:

WRF: 2009/07/23 00Z
ROMS: 2009/07/23 06Z (exact match)
SWAN: 2009/07/22 12Z

Using a Time of 2009-07-23 at 6Z:

WRF: You will view the 6 hour forecast.
ROMS: You will view the 0 hour forecast, initialization.
SWAN: You will view the 18 hour forecast.

In the Information window below, the column with Time / Depth Information will display the model run selected and the forecast hour within the run that was selected for the plot.

WRF: 2009/07/23 00 GMT (6.0 hr)
ROMS: 2009/07/23 06 GMT (0.0 hr)
SWAN: 2009/07/22 12 GMT (18.0 hr)
