[IDD #YPR-198833]: Educational entity needing meteorological data and software.

My view of the options for getting data are:

- get fed the data via the Unidata IDD

  This requires that you run a *nix system and setup our LDM software on that

- use the IDV to access data off of remote data servers

- run a NOAAPort ingest instance

  - Planetary Data is one option for NOAAPort ingest capability

  - Unidata is another option for NOAAPort ingest capability

    The Unidata NOAAPort ingest option is bundled with our LDM software,
    and, as such, requires a *nix system on which to run.

Which option you decide to pursue will, of course, be governed by your
data needs and computing/network constraints.  We will be happy to help
you get setup with the (free) software we make available.

OK.  We can help you get things setup on a Linux system, but someone at El 
Centro College
will need to be responsible for the day-to-day support/operation of the

OK.  Thirty simultaneous users all hitting remote data servers for "large"
datasets would require good network infrastructure.

20 Mbps may not be much/enough depending on how much of that bandwidth
is already in continuous use by your West Campus users.

Interesting.  I have never run the IDV in a VMware virtual machine.  I do, 
run the IDV in a CentOS 6.5 Linux VMware virtual machine, and I can say that it
works OK.  It runs much better, however, in an OS that is installed directly
on the hardware.  The reason for this is that the interactive 3D displays in
the IDV need to communicate directly with the machine's video card via OpenGL.

re: how much memory do your Windows machines have

> (2 gigs)

OK.  The IDV will certainly run on machines that have 2 GB of memory, but
large/complex displays (e.g., loops of parameter isosurfaces with interactive
2D cross sections) will either run slowly or not at all if the data domain
is large (meaning that it has lots of data points).

Just so you know, the IDV runs great on commodity PCs that are sold today.

OK.  We will be very interested to learn how well the IDV performs in a
VMware virtual machine.

Question: does the virtual machine exist on a campus server?  I would like to 
understand the lab setup so I can better answer questions that will undoubtedly
