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

Thanks Charlie,

Hii, i have a one year 5 dimensional data. i wan to extract, March-May and June-August separately. i use the code ncra -O -F -d time,3,,5,3 2008_spec.nc 2008_dm.nc. but this seems not working properly. could you please suggest better code for extraction 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)...

please reply as soon as possible

For calculating monthly anomaly i averaged the data using ncra but after using ncdiff there is an error please help me to find out. ncra 2019mon.nc mon.nc ncdiff -v T 2019mon.nc mon.nc anom.nc ncdiff: ERROR nco_xtr_mk() reports user-supplied variable name or regular expression 'T' is not in and/or does not match contents of input file

netcdf \1983-02 { dimensions: longitude = 33 ; latitude = 39 ; direction = 24 ; frequency = 30 ; time = 672 ; i want to convert this hourly data to daily data

i want to find a anomaly of a monthly data using NCO netcdf \1981mon { dimensions: time = UNLIMITED ; // (12 currently) frequency = 30 ; direction = 24 ; latitude = 39 ; longitude = 33 ;
-
can i convert this hourly data to monthly data using NCO?
-
thank you very much it works
-
here i am posting the meta data of both files using ncdump netcdf \1983-01 { dimensions: longitude = 33 ; latitude = 39 ; direction = 24 ; frequency = 30 ; time = 744 ; variables: float longitude(longitude) ; longitude:units = "degrees_east" ; longitude:long_name = "longitude" ; float latitude(latitude) ; latitude:units = "degrees_north" ; latitude:long_name = "latitude" ; int direction(direction) ; direction:long_name = "direction" ; int frequency(frequency) ; frequency:long_name = "frequency" ;...

i have two 5 dimensional netCdf datas 1983-01, 1983-02 ( Jan and Feb). I want to merge with time. i tried with code ncrcat -h 1983-01.nc 1983-02.nc file_out_1_2.nc ncrcat: ERROR no variables fit criteria for processing ncrcat: HINT Extraction list must contain a record variable to concatenate. A record variable is a variable defined with a record dimension.
