Hi Heiko,
I grabbed your dataset and I'm seeing the same problem on my local TDS
when I make the request you gave. Its running into a problem in the
ncWMS code that reads the data from the dataset and maps it onto the
desired image pixels. I'm not that familiar with this code so I'll check
with Jon on this one. Also, the TDS code is not up to date with the
ncWMS code so there might already be a fix for the problem.
I'll let you know what we find and when we'll have a fix for the TDS.
Thanks,
Ethan
