Thanks Robb...I'll pass this onto our developers. Not sure what to do about the temporal info in the parameters category (our database won't load it like that because its not part of the controlled vocabulary, but maybe we can force it to do so for this experiment). We think we can do "last 5 days" on the fly with the temporal coverage, so lets see how that works.
Thanks!

Hi Gene:

We are ready to try creating DIF from thredds records and sending them to GCMD. Attached is a sample DIF record. Its pretty minimal, and we will be adding more info later, but for now i think it will validate . Let us know if you see any problems.

I am also attaching a schema made from the DTD, that we are using for validation, in case its useful to you.

Right now, from our POV, the outstanding issue is the reletive date thing. Let us know if we can try something out.

We decided we dont need the temporal info in the parameters, so dont worry about those. Robb will be generating more tables of parameter names, for other datasets. I guess one of the jobs will be to make sure we get the names right, and map them to the right place. Is there any XML to validate against?

Anyway, Robb will be the main contact on this, but i will be working with him.

Thanks for your help,

John.

  <Use_Constraints>These files have been created from data files available at 
the NASA ESPO data archive. For each flight, the individual measurement files 
have been averaged at 1 minute, merged into single files, and saved in NetCDF 
format by NCAR/ACD (F.Wu and L.Emmons). Please consult the original files for 
additional information regarding the measurement techniques and comments on 
interpreting the data. Users of these data files are expected to follow the 
NASA ESPO Archive guidelines for use of the SOLVE data, including consulting 
with the PIs of the individual measurements for interpretation and 
credit.</Use_Constraints>
