[Esip-documentation] time_coverage_duration and time_coverage_resolution for climatological data

[Ajay Krishnan - NOAA Affiliate]

Hi Ed,

Thanks for your response but that still won't address the issue. We are
making use of the time_coverage_start and time_coverage_end attributes (to
give the user the idea that it is a decadal climatology).
We've omitted the time_coverage_resolution attribute since there is only
one time stamp.

Is it better to not include the resolution/duration attributes or any of
the time_coverage attributes for that matter, for climatological products?

Thanks,
Ajay
