Ernest,
       The basic idea for a single time step netCDF file is to add a time 
dimension and a variable to
associate with this dimension, this dimension length is one and the variable 
can be a scalar, one of the 
attribute should be _CoordinateAxisType with value equal "Time". If you have 
any question about the
standard of the netCDF file, please send your question to address@hidden.
       The other option is to use ncml to modify your netCDF file, and the IDV 
can display this ncml file
as if it has a time dimension.
       But for the better pratice of standard netCDF, you should consider the 
first option.
