Hi Kristian,

In general, you should not try to download the dataset from a catalog with TDS 
server behind it. The philosophy of data server like
TDS is to only access the portion of data you needed, not the whole dataset. 
Many datasets in the TDS are logical files, and can be
vey big (>100 G), it will hammer the server and internet if not used wisely. 

You can use the IDV scripting to get the CSV file for certain variables and 
location.
