Output netCDF

There are two ways to output netCDF data.

Method 1 (simple but (possibly) inefficient method)

• sends the data to the output file without any file predefinition
• speed depends on number of variables, dimension of variables,
  presence of an UNLIMITED dimension etc

Method 2 (efficient method)

• Enter "Define Mode" prior to predefining file contents
• predefines the the coordinate variables of the output file, the dimensions of the output variables, and optionally, the attributes of the output variables.
