[ncl-talk] read multiple binary files and plot on a x-y plot

[Guido Cioni]

Hey Gaeun,
that is certainly possible. 
If the files are not too big I don't see any problem in saving everything into one variable. Just make sure that the machine where you're running NCL has enough memory. Ideally you need to loop over the directories and over the file names, read the file, save into the variable. That's it! 

dirs=tostring(ispan(1979, 2009, 1))
fils=tostring(ispan(1,12,1))

nlat=100
nlon=100
ntime=dimsizes(fils)*dimsizes(dirs)

data=new((/ntime,nlat,nlon/), double)

k=0
do i=0,dimsizes(dirs)-1
    do j=0,dimsizes(fils)-1
        data(k,:,:)= fbindirread(dirs(i)+"/"+fils(j)+".bin", nlat*nlon, (/nlat,nlon/), "double")
        k=k+1
    end do 
end do 

This is just an idea, of course. I did not test this and you have to adapt it to your needs. Have a look here https://www.ncl.ucar.edu/Applications/r-binary.shtml <https://www.ncl.ucar.edu/Applications/r-binary.shtml>. 

Good luck
