[Go-essp-tech] CMIP5 - How to publish the same variable with two grids ?

[Stéphane Senesi]

Dear Karl and Bob

We are concerned with the ease of use of CMIP5 data by various 
communities of users. Hence, we are considering providing some variables 
both on atmospheric and oceanic grids.

For some variables/tables, we know that the ESG infrastructure will be 
OK : for instance, we can publish two additional  variables "tos" and 
"sic" in table Amon (and on the atmospheric grid), and the gateways will 
allow to discover it (we checked that already, with variable "albedo" 
and table 3hr). They are not in resquested output, and will not add much 
load to the ESG system (except for the disk space on our datanode)

However, for those tables which do already mix realms, like the daily 
table, the solution is not that simple ; I assume that mixing files of 
the same realm with various grids in a single table would cause a mess 
in the system. We are here again concerned with variables "sic" and "tos"

Can you see a way forward ?
