generating monthly climatologies/anomalies using noleap calendar

[<Mark.Collier@xxxxxxxx>]

Hello ferreters,

I am trying to use a netCDF file with the calendar type set to "noleap",
and perform a climatology calculation in the FAQ titled "How do I
calculate climatologies and climatological anomalies?"

The case using the navy winds works fine (where the calendar type
defaults to "Gregorian") - but if I use a "noleap" calendar
and try to plot (for e.g.) the climatology over the desired period
(using say the "month_reg" definition as in the FAQ example),
it fails with

 **ERROR: regridding:  only @ASN, @LIN, or @NRST regridding between calendar
types: NOLEAP, GREGORIAN

rather than plotting out the repeaing annual (climatological) cycle.

I thought that this would work nicely with the "noleap" calendar, or
am I doing something wrong here?

Ideally I would like to use my own "climatological_axes" file which
has the month_irreg definitions (including edges) for a 365 day
calendar, but I suppose that is the next step.

I can provide datasets, printouts of t and tbox, but I don't think
that is important just at the moment. I am using the latest version of
ferret under rehat, but I get the same response on the latest version for
irix.

Thanks for any help. Regards,
Mark.
