Dear all hands,

I try to get the field CLOUD out from 239 history files in netCDF format. There 
are 18 levels, 128 longitudes and 64 latitudes for each CLOUD field in each 
history file. So when I ran the ncl, it reminded me that 

"""""
fatal:NclMalloc Failed:[errno=11]:Resource temporarily unavailable
fatal:_NclBuildConcatArray : Memory allocation failure

fatal:Execute: Error occurred at or near line 6
"""""

There isn't enough memory to deal with it. What can I do? The following is the 
CLOUD.ncl I used to get the CLOUD out.


          begin
            diri = "/disk/cj2/ccm/ccm-mqz/run.amip2/"  ; directory where fil
es reside
            fils = systemfunc ("ls "+diri+"19??-??.nc")
            f    = addfiles (fils, "r")   ; note the "s" of addfile

            ListSetType (f, "cat")        ; concatenate or "merge"
            T    = f[:]->CLOUD
            print (dimsizes(T))           ; T will have 60 time steps
            T!0  = "time"
            T!1  = "lev"
            T!2  = "lat"
            T!3  = "lon"
            T&time = f[:]->time           ; time coord variable
            T&lev  = f[0]->lev            ; get lev from the 1st file
            T&lat  = f[0]->lat            ; get lat from the 1st file
            T&lon  = f[0]->lon            ; get lon from the 1st file

            filo = "./nc/CLOUD.nc"
            system ("/usr/bin/rm "+filo)  ; remove any pre-existing file
            fo   = addfile(filo , "c")    ; open output file
            fo@title = "CLOUD from model files"
            
            fo->CLOUD = T                    ; write CLOUD to a file
          end

Anyone knows how to deal with this using any netCDF softwares? I can't insatall 
 
nco on my SUN computer now. Thanks in advance.

Best regards,
Qiaozhen
