[ncl-talk] Script for multiple directories and multiple locations

[Muhammad Omer Mughal]

Hi Dennis


I have made the changes in the attached script. I am getting the following error. Can you or any one at NCL select a solution to my problem.

The question is not clear  (... a least to me...)

---
 6 ; Make a list of all files we are interested in
 7   DATADir = "./"
 8   FILES = systemfunc (" ls -1 " + DATADir + "wrfout_d04* ")
---

http://www.ncl.ucar.edu/Document/Functions/Built-in/systemfunc.shtml
Look at Example 6

---
Other options based on the Example 6 which has directories a1, a2, ..., a20

DATADir  = "/Some/dir/with/WRF/data/"
cmd         = "find " + DATADir + "a* -type d -print"
dirWRF    = systemfunc(cmd)
print(dirWRF)

n_dirWRF = dimsizes(dirWRF)

do n=0,n_dirWRF- 1      ; loop over directories

     f = addfiles(dirWrf(n)+"wrfout_d04*nc", "r")
       :
end do

=====

dirWRF = str_split(systemfunc("echo "+ DATADir), " /")
print(dirWRF)

=====
You can experiment

Hi


Kindly see the attached script


On the line number 7 I need to add multiple directories containing the wrfoutdo4 file and


on line number 26 I need want to write a loop that can change  locations one by one and for each location gives the output as wind speed.

I would be grateful for your help and support.
