hi Serge!

This error is related to your input data. Without it, it's really hard (and I mean impossible) to comment on this.

cheers

thank you ralf,

I join the information of my input data below

Serge,
is the upload impossible for any reason?

Ralf,

Normally everthings is fine but I wondering if the warning message will not have any have any impact on my output file.

Can I download the input from somewhere else? you could also use MPI's ftp server: ftp.zmaw.de/incoming, user anonymous, passwd: an email-address

Some attributes must be evaluated to understand the data. One of them is the attribute valid_range to find the valid range of the data.
The valid_range attribute of your data can't be evaluated because the data type (short integer) differs from the data type (float) of the array:

 float uwnd(time, lat, lon) ;
 uwnd:valid_range = -32766s, 27234s ;
