Hi TDS folks,
A user just brought to my attention that the "wind" maps normally produced
by ncWMS are no longer working. I upgraded to TDS Version 4.3.17-SNAPSHOT -
20130424.1325, so perhaps it is just a bug in the latest version?

ncWMS normally combines variables with standard_name "eastward_wind" and
"northward_wind" into a combined "wind" velocity vector map. This is no
longer working for any of our atmospheric forecast models. To test this for
yourself, try either of the following Godiva2 links: click on "wind" and an
error will be produced: "Error getting data from server"

In contrast, I noticed in our ocean forecast models that the combined
"sea_water_velocity" is still successfully generated by ncWMS for variables
with standard_name "eastward_sea_water_velocity" and
"northward_sea_water_velocity":

Thanks in advance for your help in addressing this issue!
