[ncl-talk] same data but different spatial pattern

Wed Feb 13 06:40:59 MST 2019

Hi Toni,
I understood your sound explanation. How could I create an empty array and
every loop will paste that array? Actually, I need to extract whole hourly
data over land for further PDF analysis. I tried to plot first because I
wanted to confirm that I could produce plot correctly for whole hourly
data.

Any suggestions would be appreciated?

Best wishes,
Jalal
