How can i deal with big size datasets using NCO for eg: after using ncdiff command i get this ERROR nco_malloc() unable to allocate 25510004352 B = 25510004 kB = 25510 MB = 25 GB

Hii, I am trying to subtracting 2 netcdf files using ncdiff command. ncdiff 2015mam_new.nc 2008mam_new.nc iod_nu.nc i got an error message please help me to solve this issue

i have 2 netcdf files. both are monthly data of march to may in the years of 2015 and 2008. i need to subtract this these 2 files. ncdiff not working properly. both data's are 5 dimensional. pls suggest me a better command to resolve this. Thanks in advance Aravind

can anyone please help me sort out this problem?

i am now tried with ncdiff -v time 2019mon.nc mon.nc anom.nc but null data is coming.

Still I am facing the same problem. netcdf \2019mon { dimensions: time = UNLIMITED ; // (12 currently) frequency = 30 ; direction = 24 ; latitude = 39 ; longitude = 33 ; variables: double d2fd(time, frequency, direction, latitude, longitude) ; d2fd:_FillValue = -32767. ; d2fd:missing_value = -32767s ; d2fd:units = "m2 s radian-1" ; d2fd:long_name = "2D wave spectra (single)" ; d2fd:cell_methods = "time: mean" ; int direction(direction) ; direction:long_name = "direction" ; int frequency(frequency)...
