[ncl-talk] avoiding loops

[Rashed Mahmood]

Hi Micah,
Did you try using the addfiles function in NCL:

https://www.ncl.ucar.edu/Document/Functions/Built-in/addfiles.shtml

For example:

   fils = *systemfunc*
<https://www.ncl.ucar.edu/Document/Functions/Built-in/systemfunc.shtml>
("ls *.nc") ; file paths
   f    = *addfiles* (fils, "r")


You would need to make sure that "ls *.nc" results in the correct order
with respect to time and day.

Cheers,
Rashed
