Re: ADCIRC OPeNDAP Directory Contents
From: Brian Blanton

This OPeNDAP-accessible directory contains 
output files form the operational ADCIRC 
nowcast/forecast for the US east coast and 
Gulf of Mexico.  

The simulations are driven by the NCEP 
NDAS (formerly EDAS) for the 
nowcast, and NCEP NAM (formerly ETA) 
for the 84h forecast.

The ADCIRC computational grid is a medium resolution 
grid that extends from 60W westward to the coastline. 
The grid definition file (fort.14 in ADCIRC parlance) 
is in the file ec_95d.grd (linked to eastcoast_95d_ll.grd).
There is a netCDF version in the file eastcoast_95d_ll.nc,
with the following CDL:

        node = 31435 ;
