NorStore Research Data Archive: Guidelines for ingestion of NorESM output¶
The recommendations presented on this page are based on discussion between Alok, Mats and Ingo. Please feel free to comment and modify them.
The access point to NorStore’s Research Data Archive is http://archive.norstore.no
For testing purposes, the alternative site http://archive-test.norstore.uio.no should be used.
Metadata recommendations¶
BibliographicCitation¶
Specify “http://cmip-pcmdi.llnl.gov/cmip5/terms.html” as value.
Coverage¶
Please follow DCMI recommendations when specifying coverage.
Box (http://dublincore.org/documents/dcmi-box)¶
If coverage is global, use:
(leave rest unspecified)
Period (http://dublincore.org/documents/dcmi-period http://www.w3.org/TR/NOTE-datetime)¶
Specification of start- and end-year required (optionally, month and day):
The value of //scheme// should be always set to W3C-DTF. The value of //name// can be left blank.

Boundary conditions¶
piControl: -Prescribed atmospheric concentrations of pre-industrial well mixed gas: Carbon Dioxide -Unperturbed Pre-Industrial Land Use -Prescribed concentrations or emissions of pre-industrial natural aerosols -Prescribed concentrations or emissions of pre-industrial natural aerosol precursors -Prescribed atmospheric concentration of pre-industrial short lived (reactive) gas species -Prescribed concentrations or emissions of pre-industrial short lived (reactive) aerosol species -Prescribed atmospheric concentrations of pre-industrial well mixed gases: excluding CO2
Label¶
If the dataset matches a NorESM case then specify the case name as label, e.g., //NAER1850CNOC_f19_g16_06//.
Rights holder¶
If in doubt, specify
Project¶
For CMIP5 output, specify //Integrated Earth System Approach to Explore Natural Variability and Climate Sensitivity (EarthClim)//
Conforms to¶
If in doubt, specify “//Climate and Forecast (CF) metadata conventions//”
Provenance¶
In case the output has been compressed, specify “//gzip compression of restart files and conversion of history output to compressed NetCDF-4 format//” and state the time stamp of the last compressed restart file.
Please add additional provenance entries in case further manipulations have been performed on the output.
