[ncl-talk] Questions for dsgrid3

[Sujeong Lim]

Hello, I have a question for dsgrid3.

I want to convert my unstructured data to 1deg data. (ex. T(time, lev,
ncol) -> T(time, lev, lat, lon)

As I know, I can use ESMF_unstruct_to_0.25deg.ncl and degrid3.ncl. Is it
right?


As a practice, I tested degrid3 example.

Though I copied the example in the ncl homepage, it showed error message.
(Red line)

fatal:Number of dimensions on right hand side do not match number of
dimension in left hand side
fatal:Execute: Error occurred at or near line 56 in file degrid3_org.ncl

How can I do?

Sincerely,
Sujeong
