[ncl-talk] Percent calculation

[Md. Jalal Uddin]

Hi, sir (Rashed),

pcp_ratio  is now 3 dimensions (ntim, lat, lon). Now, I want to produce a
spatial map that needs 2 dimensions (lat, lon). How can I use do loop over
time instead of using dim_sum_n_Wrap or dim_avg_n_Wrap? Could you suggest
to me?

Best regards,
Jalal
