I checked the wiki pages. The maps looks great. We will be able to utilize the wind speed contour and wind vector maps during the demo. And, Rudy, thanks much for the visual inspections. That would be very useful to describe the maps.

If the maps are going to be used to describe the overall characteristics of wind data in China, a simple WMS rendering would be fine. Now I'm trying those maps with a couple of browser based clients and IDL/ENVI. I'll get back to you with comments/requests regarding its proper format for the demo.

Many thanks to all of you! Jinsoo 16:12, 10 May 2006 (EDT)


Point # 2 / Low Wind Speeds Over Land. These are 10 meter winds. It was understood the original plan was 50 meter, The GFS model used for these averages gives us the following options:

  1. Standard pressure levels
  2. Sigma 0.995
  3. 10 meters above sfc
  4. 0 to 30 mb above surface avg
  5. 1829 meters above sfc
  6. 2743 meters above sfc
  7. 3658 meters above sfc
  8. Maximum wind level

I was told to try 10 meter first. But I'm not surprised that winds at this level are a little weak over land, due to friction interaction at that level. If you want to try something else, I could whip up another file rather quickly ~ would just be a matter of changing a variable name in a script, changing some nc metadata, etc. and rerunning grads.

The averaging function documentation is here: http://grads.iges.org/grads/gadoc/gradfuncave.html Will provide limited insight however. But I highly doubt this is the cuase of the low wind speeds.

Point # 3/ NCDC WCS Server Status. We have had a fire in our camp I have had to drop everything to resolve lately. Just starting to get back to this. As far as I know, the WCS service is built into the TDS. I've simply attached this service to the .nc global file. If there is more to do, I am not sure and would appreciate any feedback if this is inadequate. DanSwank, NCDC-NOMADS 16:12, 10 May 2006 (EDT)

NCDC Backup TDS Server is operational
As a backup, just in case anything happens to our server during the demo, we now have a backup available at the following address:

Perhaps you could integrate an "alternative source" option in the client so it knows to try multiple addresses if the primary one fails.
