Re: [ferret_users] how to do this with "repeat"?
Hi Antonio,
If I understand correctly what you want to do, it would be this,
averaging 1:10 in time
let sst_fav_tav =sst13[X=10w:4w@FAV:7,Y=35n:38n@FAV:7,L=1:10@AVE]
Or, if you want the x and y averaging at each time, you would just
define the fill in x and y and then use the desired time steps to save
or in whatever other calculations you want to do.
let sst13_fav = sst13[X=10W:4w@FAV:7,Y=35n:38n@FAV:7]
save/file=myfile.nc/L=1:10 sst13_fav
In any case this shows how to apply the @FAV transformation to a region
in x and y.
Most often, the REPEAT command is not needed. Ferret operates over
entire grids or axes, or the subsets you specify with qualifiers /X=
/Y= or SET REGION/X=/Y= or in square brackets [T=].

Hi,
I have a parameter called sst13 where I want to perform a @FAV
for the X and Y axes averaging along the time axis so I get I new
parameter, i.e.
"sst13_fav" with the new values averaged. But don't know how to put
this into words. I've tried something like this (and around this), but
doesn't work:
repeat/l=1:10 let s=sst13[X=10W:4w,Y=35n:38n,[X=@FAV:7,Y=@FAV:7]
yes? show data/variables
currently SET data sets:
1> ./sst13.nc (default)
name title I J
K L
SST13 PHSSTA[X=12W:2W,Y=34N:49N,L=120 1:201 1:301 1:
1 1:99
on grid GHJ1 with -1.000000E+34 for missing data
X=12W:2W(358) Y=34N:49N Z=-0.5:0.5
time range: 17-SEP-2004 00:00 to 21-NOV-2006 00:00
Best regards,
Antonio
