NAME

roms2vdf - Transform ROMS netCDF data into a VDC

SYNOPSIS

roms2vdf [options] roms_ncdf_files... roms_ncdf_grid_file vdffile

DESCRIPTION

roms2vdf reads 3D and 2D variables from one or more ROMS output netCDF files, as well as grid data from one ROMS NetCDF file, wavelet transforms the data, and stores it in the VDC associated with the .vdf file vdffile.

OPTIONS

-vars <vars>: Variables to convert. A colon delimited list of the 3D and 2D variables you wish to transform. Their names must appear in the .vdf file, vdffile. The variable ELEVATION will always be created. The default is to convert all time-varying 3D and 2D variables defined in both the .vdf file and the ROMS netCDF files.
-numts <number>: Specify the maximum number of time steps to convert. After converting number time steps, no further processing will take place.
-level <level>: See raw2vdf
-lod <n>: See raw2vdf (VDC2 only).
-nthreads <n>: See raw2vdf (VDC2 only).
-help: Print a usage statement and then exit.
-quiet: Operate quietly, only reporting fatal errors.

EXAMPLES

The command

    roms2vdf romsout1.nc romsout2.nc romsout3.nc romsgrid.nc mydata.vdf

transforms all of the variables at all of the time steps found in the ROMS netCDF files romsout1.nc, romsout2.nc, and romsout3.nc that match the variable names and time stamps found in mydata.vdf. The file romsgrid.nc contains the time-invariant variables that describe the computational grid, such as h and s_rho.

The command

    roms2vdf -varnames u:v:w romsout1.nc romsout2.nc romsgrid.nc mydata.vdf

is similar to the above example except that the converted variables are limited to the three 3D velocity components, u, v, and w.
