not sure if this is what you mean, i just make it available thru the various 
services, then its up to a client to do the subsetting

in the example, the file lives at C:/data/narccap/pr_mm5p_fixed.nc

Hi John,

also if I may ask another question: when you say we can do spatial sub-setting, do you mean that you have configured this (single) file in TDS and have used the standard UI to make a spatial request ? If so, could you send an example TDS configuration for this ?

thanks, Luca

Hi John,

That's fantastic!  Great news!

I haven't worked with ToolsUI or IDV before; could you point me towards an intro of some kind?

Thanks a bunch!

Hi Seth:

http://www.isse.ucar.edu/mcginnis/narccap/thredds-test/pr_mm5p_fixed.nc

works fine (the other not). We can do spatial subsetting on it. You might want to check that the domain looks correct, using ToolsUI or IDV (or NCL)

Looks like a good job to me, my only minor comment is

   int Lambert_Conformal(ncl4=1);

could just be

  int Lambert_Conformal;

but it doesnt actually matter.

Hi John,

This is Seth McGinnis; I'm working with Larry McDaniel on the NARCCAP project.

I have placed two sample NetCDF files on Lambert conformal grids here:

http://www.isse.ucar.edu/mcginnis/narccap/thredds-test/pr_mm5p_trunc.nc
http://www.isse.ucar.edu/mcginnis/narccap/thredds-test/pr_mm5p_fixed.nc

_fixed is the same as _trunc, but I have tried to massage it to be CF-compliant. (I'm still learning the CF standard, so I'm not sure that I succeeded.) Let me know if either of those will work for testing whether TDS can do spatial subsetting on this map projection.

I *believe* that the only other map projection we'll have to deal with is polar stereographic, but I'm not certain about that, and I don't have any data files from those models available.

Thanks,

-Seth

Hi Larry:

Yes, we can handle lambert_conformal_conic, but i need to get a sample file before i can be sure.
