[Go-essp-tech] Minutes: 1/6/10 Output Variable Telecon

[Sylvia Murphy]

HI Bryan,

You said "i think the output variables that actually appear in the dataset need to get TIED [my emphasis] to the model components".

The way ESG should work, is that there will be a link (on the outputs tab) in the model metadata display pointing to the datasets.  I believe the variable name will be listed in those names. 

If a user clicks on one of those links he will get a lot of metadata about the files including the CF information about the variables.   

When you say "tied" is this what you were thinking or do you want to see output variables listed (as a list) on the model metadata display?  If so we are going to have to find a way to have the two sides of ESG, the dataset side and the model metadata side communicate with each other.

Cheers,

Sylvia

We have the model realm in the netcdf attributes, and we have the model realm in the component, and we need to stitch them together down that seam ... that's actually the key thing that needs to happen in the merge.

Thanks Gerry for making it into the office with 12 inches of snow on the ground and more on the way!  It was a useful conversation.  Here are some salient points:

>> 
>> My personal opinion:  Since this information is not actually factual for the model component it would be displayed with AND the factual information will be available in ESGs dataset display,  this list of requested CMIP5 variables has limited utility in the ESG model metadata display.
