[Go-essp-tech] What is the risk that science is done using 'deprecated' data?

[Ashish Bhardwaj]

Hello Jamie,

At IPSL CMIP5 production datanode, every change in dataset is given a 
new version.

I can understand your concern for versioning of datasets. It is a 
combined effort of all institutions publishing CMIP5 data to 
gateways/P2P ESGF node to conform to CMIP5 best practices.
Since words are important, instead of practices, I would say that there 
should be some policy document.  I am also aware of the fact that CMIP5 
teams are giving their best efforts to meet user requirements.

Regards,
Ashish
