NAME

cam2vdf - Transform CAM netCDF data into a VDC

SYNOPSIS

cam2vdf [options] cam_ncdf_files... cam_ncdf_grid_file vdffile

DESCRIPTION

cam2vdf reads 3D and 2D variables from one or more CAM output netCDF files, as well as grid data from one CAM 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 CAM 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

    cam2vdf camout1.nc camout2.nc camout3.nc mydata.vdf

transforms all of the variables at all of the time steps found in the CAM netCDF files camout1.nc, camout2.nc, and camout3.nc that match the variable names and time stamps found in mydata.vdf.

The command

    cam2vdf -varnames u:v:w camout1.nc camout2.nc camgrid.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.
