Hello,
 
Thank you so much. Previous reply was really helpful to me.
However, I still have a problem.
I added the extension ".he2" to the hdf filename, but I have an error message as below.
 
fatal:(he2_file) does not reference a file
fatal:Execute: Error occurred at or near line 49 in file wgtavg1.ncl

I don't even know exactly the meaning of the error message.The following is my changed code. Which part am I wrong in the code?
Thank you
