Re: Time Axis again

[verschel@xxxxxxxxxxxxxxxxxxxxx (Mark A. Verschell)]

Jose,

	The only way that I know how to do this is to modify the NetCDF file to
tell ferret that the axis is "regular", i.e., has a constant time step. This
allows ferret to avoid storing all the coordinates.

	What you would do is:

ncdump mydata.cdf > mydata.cdl

edit the file, and where the definition of the variable that is the time axis
is, add the line:

                TIME:point_spacing = "even" ;

For example:

        float TIME(TIME) ;
                TIME:units = "DAYS since 0001-01-01 00:00:00" ;
                TIME:time_origin = "01-JAN-0000" ;
                TIME:point_spacing = "even" ;

Then, recreate the NetCDF file:

ncgen -o mynewdata.cdf mydata.cdl
