Re: [ferret_users] saving the file of ensemble members

[saurabh rathore <rohitsrb2020@xxxxxxxxx>]

Dear Satyesh,

The way that you mentioned is more like

repeat/l=1:312:1 (save/append/file=ensemble_mean.nc var;set mem/size=xxxx)

but I am having 11 models so this size of saving data is not possible as in my final variable I am having 5 dimensions i.e. i,k,l,k,m where i=1:360, j=1:126, k=1:36, m=1:11. here m=1:11 are the 11 models

sh gr histzd
    GRID (G013)  Ensemble Aggregetion Grid
 name                           axis              # pts                      start                      end                           subset
 LON                      LONGITUDE          360mr                  0E                           1W                            full
 LAT28_153             LATITUDE           126 r                    62.5S                       62.5N                        full
 LEV1_36                  DEPTH (m)           36 i-                     5                           1984.9                      full
 HISTM                        TIME               312 r               30-JAN-1980 00:00     30-DEC-2005 00:00       full
 ENSEMBLE           E (realization)        11 r                             1                             11                      full

 normal    F

now how to save this massive amount of data ?

regards, saurabh

Dear Satyesh,

thanks for your email. I will get back to you after trying this method.

Hi Saurabh,

  You can use 'save' command with 'repeat' loop, every time listing just one subset of the full ensemble variable. For example if your variable is 'var', find the 'I' index range (by 'sh data') and use the following: 

 Suppose 'I' index ranges from 1 to 144, then your syntax will become as follows (you can further look what 'ilimits' and 'klimits' etc. does)  :

save/file=Yourfile.nc/ilimits=1:144/i=1 var[d=1];

repeat/range=2:144/name=aa (save/file=Yourfile.nc/append var[d=1,i=`aa`;])

I hope this is relevant and helps you.

Dear Ferreters,

I am having 11 CMIP models data in lat,lon,time,depth. I made an ensemble variable of dimension lat,lon,depth,time,ensemble_member i.e. 360,180,36,312,11. which is 360 longitudes point, 180 latitudes points, 36 depth levels, 312 time steps, 11 no. of models.

i want to save this 5-dimension ensemble variable into netcdf file. Is there any efficient way to save as my HPC is limited by memory.

cheers, saurabh
