[ncl-talk] How to combine many nc files from different folders

[Dennis Shea]

Given your screen shot, the following will likely work:

fils= *systemfunc*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/systemfunc.shtml>("ls
[1-2][8-9-0-1]*/*nc")
print(fils)

f    = *addfiles*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/addfiles.shtml>
(fils, "r")
x   = f[:]->X
*printVarSummary*(x)
