Hello,

Concerning the ESG [Earth Systems Grid] comments.
I passed the email to esg-support. The response:

---
The ESG support team is more than willing to answer user
inquiries and facilitate data access.  Please post
your questions to the email address below.
Thank You

Some questions posed to me off-line:

What exactly do they mean by window size datasets? 
Do they mean a subset of the data for a specific 
range of coordinates ?

They say it took several hours to download one field. 
This can be true if the dataset was on the Mass Storage
System since it may take time to retrieve the files it they
are not online.

Could they specify which file(s) they experienced delays?

Otherwise the only possibility is that they have a really slow 
internet connection ...
