[ferret_users] time axis for perpertual year run

[Glenn Carver <Glenn.Carver@xxxxxxxxxxxxxxxx>]

I have a monthly mean netcdf files from a run of a model which has run  
2001 repeatedly. Each year is in one netcdf file. I want to view the  
files as a time sequence rather than treat them as a climatology but  
am not sure how best to create the new time axis. As each file is for  
'2001' I need to create a new time axis in order to see the sequence  
of years.  I've done this by:

def axis/t=1:60:1 y5

I need use the @asn operator for each netcdf file and overlay the  
years, like this:

def axis/t=13:24:1 y2
def axis/t=25:36:1 y3

let/d=1  z1=z[gt=y5@asn]
let/d=2  z2=z[gt=y2@asn]
let/d=3  z3=z[gt=y3@asn]

and plot by:

fill z1
fill/over z2
fill/over z3

The first plot 'fill z1' gives a time axis for the full 5yrs but only  
the first 1-12 months filled as the first netcdf file has only 12  
months. The next commands then fill months 13-24 and 25-36 respectively.

This works just fine but the problem is that I get a gap between the  
months 12-13 and 24-25 (see plot).  I'd like the figure to be  
continuous.

Anyone know a way round this?

Thanks,   Glenn
