Hello. For this purpose, you can use Rstudio and complements for reading .nc files. First, put all the files in one folder, then write a code to read all of this, mostly creating a unique matrix for storing it. Then, you can read the properties and extract the values to other matrices or variables.

Finally, do some statistical analysis to compare the mean values.

Tip: If you don't know how to use Rstudio, you can use ChatGPT for guidance.

Thank you Christian for this answer, i can use Rstudio, but the problem is that the file is netcdf-2 this kind of format, it is my first time to deal with such kind of format, but i will try Rstudio, then see what i will get.

Hi,

Use CDO for this.

cdo ensmean ifile1 ifile2 ifile3 ifile4 ifile5 ifile6 ofile

or simply

cdo ensmean *.nc ensmean.nc (it collects all nc files in the folder and calculates the ensemble mean of all variables if the same variable is found in the files.)

Now, you may have to write a shell script with cdo command to change the name of the variable with the member name.

Then,

cdo merge *.nc merge_all.nc (it includes ensemble mean). Now, you can work everything with merge_all.nc file.

Hope this helps!

Cheers,

Kishore

Thank you Kishore Ragi, will try that
