[ferret_users] Taylor Diagram

["markus.mingel@xxxxxxxxx" <markus.mingel@xxxxxxxxx>]

Dear Ferreters,

I am trying to compare the mean annual cycle of simulated surface temperature 
from different models with observations in a Taylor diagram. 
Both models and data have the dimensions of 180x360x12, where 12 are the 
months. How can I do that with ferret?

I looked at the sample scripts and in case of the file bias_zonalanommap.nc 
all the statistics have already been computed, so I miss how to get all the 
variables needed  to build the diagram starting from gridded datasets.

Thanks into advance for the help,

Best Regards
Markus
