[Go-essp-tech] Fwd: Expected number of variables for which quality control will be needed

[Bryan Lawrence]

Hi Karl, Martina

So are we really expecting PCMDI to look at more than 10,000 plots per 
day as part of QC level 2?

(Martin's numbers are on an internal wiki, but a back of the envelope 
calculation goes something like: 
 - one plot per atomic data set,
 - o(10^6) atomic datasets
 - 100 days
 - o(10^4) per day at PCMDI given BADC and DKRZ doing a negligible 
amount cf PCMDI under current plans)

Cheers
Bryan
