Use of NetCDF-Formatted Wind Fields from OWI in ADCIRC

This new OWI file format was developed by Alex Crosby and his team at Oceanweather Inc. Most of the ADCIRC code to handle these new input files was implemented by Casey Dietrich.

ADCIRC has now been updated to allow the usage of NetCDF-formatted atmospheric fields from Oceanweather Inc. (OWI). In this new format, the surface pressure and wind fields have flexibility to represent different storms with different fields, to track storms with moving fields, and to vary resolution of the fields in both space and time. These updates have been added to the latest development version of ADCIRC, and they will be available in the next release version. These new fields are read by ADCIRC using the NWS=13 parameter and a new input file.

The following animation shows the use of this new file format in an ADCIRC simulation for the wind fields due to Hurricane Charley (1999). Note that Charley is one of several storms during this period, and each storm is represented by a moving field overlaid on a coarser background field.

In the rest of this page, we describe the new input file format, how it is used in ADCIRC, and then provide a set of example files.
