Hi Tommy,
I'm involved in a project at the Bureau of Meteorology known as AIFS :
the Australian Integrated Forecast System, which is installed
operationally in our forecasting centres Australia wide, as well as the
Fiji Met Service.
One of the consistent messages from users has been the need for better
integration of applications, high levels of flexibility and
extensibility, and the need to save time and effort on the part of the
meteorologists.
In an effort to meet these needs, we have been using VisAD to develop
our "version 2" applications, and so far we have:
* a Tropical Cyclone module which went operational this southern summer
* a Marine Forecasting System (user adjusts model guidance to produce
graphical & text products) which is being trialled in one office
currently
* developed classes to allow some VisAD data structures to be
stored/retrieved as XML data (which we plan to release publicly soon)
* begun work on a "remote data server" facility to allow rapid browsing
of numerical model data
* begun work on a Wind Profiler display
Experience to date shows that VisAD is an extremely useful basis for
this work, and with it's powerful data model, significantly reduces the
pain of data integration.
Re collaboration, we will gladly work with others where there is a
common interest.

The time to "learn" VisAD is decreasing rapidly in my opinion. Now that
there are some excellent tutorials available, my experience is that the
right person (Java literate, preferably with a Maths background) can be
productive after one week. I had a 2nd year student producing useful
code in week 2, and a demonstration application in 8 weeks. The
assistance of Bill, Tom and others from Uni of Wisconsin, and Don et al
from Unidata has been invaluable.
Hope this helps,
James
