[Go-essp-tech] Data file gaps

[Karl Taylor]

Dear Jennifer and all,

concerning: "While checking on these gaps, I noticed that not all 
variables in an atomic dataset span the same time range"  ...

For some datasets, we requested different periods for different 
variables.  For example, for frequency="day"  only a subset of the 
variables were requested for all times and experiments.  See
one of the links under the "CMIP5 Model Output" heading of the "guide": 
http://cmip-pcmdi.llnl.gov/cmip5/guide_to_cmip5.html
or go directly to 
http://cmip-pcmdi.llnl.gov/cmip5/docs/standard_output.pdf and look at 
the "day" table.

Not sure whether this covers all the cases you've found.

Best regards,
Karl
