Debian Wheezy To Have Multi-Architecture Support
I tried to tag it as "badlink" and by accident ended up with multiple incorrect tags that I can't delete. What a winning interface.

a return which is long overdue (plus achievements!)
Welcome back! I haven't posted or hardly read the comment threads in a long while for similar reasons. Why get involved if you can only do it halfway (or less)? But today get got an e-mail about a new user journal update! :-)
The achievements are still somewhat new. Somewhere around April Fools Day I believe. Goofy but still kind cool.

Dude, get with the timecube there are no time "zones".
Replacement For Aging Doppler Radar Being Tested
Your comments are helpful, but still not 100% accurate.
The rotation rate of the radar is faster and the volume updates are faster as well. CASA currently operates on a one minute "heartbeat" where many scans at different elevations are completed which cover a large portion of the total reachable volume.
While CASA radar does not provide a traditional "full volume" scan this is by design. For the first time we are dealing with a weather sensor that reacts to the environment automatically adjusting it's scanning pattern to be appropriate to the weather and follow storm paths.
CASA is running on a range much shorter than Nexrad. The current testbed is actually at 40 km range. The primary flaw or gap we are filling is the lower atmosphere which, as you stated, is due to the Earth's curvature and therefore a short range is most desirable.
The CASA radars are indeed full Doppler (not just marine radar) with dual polarization as well. They are currently mechanically steered but the technology under research will adapt quite easily to electronically steered beams from phased array radar panels as well.
As a side note the Nexrad system is indeed being upgraded in place to handle dual polarization which should improve snow detection and precipitation estimation.
Also "Super-res" is being deployed. This is a software change that makes the radar appear to have greater resolution by changing the way the signal is processed into smaller "bins". Literature seems to indicate this will help the human observer of the radar, but with the increased visual noise the algorithms will not see a significant improvement.
Full disclosure: I am a graduate research assistant working on the project.
