Re: [ferret_users] To change the calender type

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Hi -
You can do this in Ferret as well, in one of two ways depending on what 
you're trying to correct.

1) If the calendar in the file is noleap, but it doesn't say that in the 
file, you can do:

yes? use filename.nc
yes? set axis/calendar=noleap `var,return=taxis`

And then the calendar will be treated as a NOLEAP calendar in the Ferret 
session, and if you write out the data, the time axis will be NOLEAP

2) If the calendar in the file is gregorian, but you want to interpolate 
your data onto a noleap calendar axis,
then define the new axis and regrid to it;

yes? use filename.nc
yes? DEFINE AXIS/CALENDAR=noleap/     (add the correct time origin, time 
range and units)
yes? let newvar = var[gt=new_time_axis]
