[THREDDS #PMC-685007]: Problem with radar subset service



Hi Joe,

Thanks for the heads up. We will take a look to make sure there isn't an IDD or 
a TDS issue. In the mean time, you might try accessing thredds.ucar.edu which 
is running TDS 4.3 (motherlode:8080 is still running TDS 4.2).

We are about to announce the transition from motherlode.ucar.edu:8080 running 
TDS 4.2 to thredds.ucar.edu running TDS 4.3 (our current stable release). They 
are both available now and will remain so until 1 July when motherlode:8080 
will be upgraded to TDS 4.3. Then on 1 August we will either redirect 
motherlode:8080 to thredds.ucar.edu or block it all together.

The main changes between TDS 4.2 and 4.3 are listed here (the main focus of the 
page is for people running a TDS but the list should still be useful):

http://www.unidata.ucar.edu/projects/THREDDS/tech/tds4.3/UpgradingTo4.3.html

Accessing radar data, you probably won't see too many changes. But there are 
some changes to the netCDF Subset Service, mainly cleaning up the interface and 
making it work the way advertised.

Hope that helps,

Ethan
