[Esip-documentation] time_coverage_duration and time_coverage_resolution for climatological data

[Armstrong, Edward M (398G)]

Hi Ajay,

I would suggest you could use this three attributes to described the time series start/stop and time step:

time_coverage_start

string

Describes the time of the first data point in the data set. Use the ISO 8601:2004 date format, preferably the extended format as recommended in the Attributes Content Guidance section.

time_coverage_start = "2016-09-01T08:12:01" ;

required

ACDD 1.3

time_coverage_end

string

Describes the time of the last data point in the data set. Use ISO 8601:2004 date format, preferably the extended format as recommended in the Attributes Content Guidance section.

time_coverage_end = "2016-09-01T08:17:59" ;

required

ACDD 1.3

time_coverage_resolution

string

Describes the targeted time period between each value in the data set. Use ISO 8601:2004 duration format, preferably the extended format as recommended in the Attributes Content Guidance section.

 time_coverage_resolution = "00:05:58";

recommended

ACDD 1.3

Subject: [Esip-documentation] time_coverage_duration and time_coverage_resolution for climatological data

Hello All,

I am looking at populating global attributes for a dataset which contains monthly mean temperature for 1995-2004.

I had recommended
:time_coverage_duration="P10Y" ;
The science steward is not convinced, and perhaps rightly so, because it is not a 10yr field but a 1 month field which is a mean of 10yrs of that month. How should the global attribute be populated in this case?
What about the time_coverage_resolution attribute?

Are such complicated cases outside the purview of ACDD?

Thanks!
