NCEP Reanalysis netCDF in traj

[Matt Jeglum]

Hi all,
I am attempting to use netCDF files from the NCEP/NCAR reanalysis to make trajectories with a
modified version of traj.gs.  My impression is that I need to create a templted control file to make this
work.  My main issue is with creating the control file, and in particular finding the necessary
variables using an ncdump -h  to specifiy pdef projection, reference points and reference lat/lons.
Any help would be appreciated.
