[ncl-talk] an error occurred while adding a variable to a file, check to make sure data type is supported by the output format

[xiaoming Hu]

I wrote a simple script (attached below) to concatenate among different files.

But I got error message in a simple line:

fout->latitude= latitude_pre

see my screen output:

Any idea what is happening?

Thanks a lot

My NCl script:
