The IDL interface to netCDF is supported by RSI. You should be able to
open the file for writing, change the values of a variable, and rewrite
it with the appropriate IDL routines:

  NCDF_OPEN
  NCDF_VARGET
  NCDF_VARPUT
  NCDF_CLOSE

You must use the keyword "WRITE" with NCDF_OPEN to open a file for
modification, since the default in IDL is to open netCDF files as
read-only.  You only need NCDF_VARGET if the new values depend on the
old values.
