[ferret_users] Ensemble analysis with ferret V68
HI all,
I am glad to discover the last ferret v68 and its capacities to open
dataset up to 6 dimensions.
Very, very nice.
Here is my first example with some realizations from OCMIP5 output
! Build a list of files to open
yes? let files=spawn("ls
/prodigfs/esg/CMIP5/merge/IPSL/IPSL-CM5A-LR/rcp85/mon/atmos/Amon/r?i1p1/latest/tas/tas_Amon_IPSL-CM5A-LR_rcp85_r?i1p1_2006_2100.nc")
! Open each files
yes? repeat/range=1:`files,return=isize`/name=s (let file=files[i=`s`] ;
use "`file`")
! Define an aggregation with previous data set opened
yes? def data/aggregate myens=`spawn("seq -s, ($N_OPEN_DSETS)")`
and that's it, you have defined a new dataset with all the realizations
seen on the M dimension.
yes? show data 4
currently SET data sets:
4> MYENS (default)
name title I J
K L M N
HEIGHT height ... ... ...
