Element Description

The Granule UR element provides the universal reference id of the granule, which is assigned by the data provider. As a result, the id will vary from granule to granule.

Best Practices

Essentially, the Granule UR should match the granule's long name.

Examples:

Granule Long Name: AIRS2CCF_NRT.006:AIRS.2018.10.18.189.L2.CC_IR.v6.0.31.0.R18291162512.hdf

Granule UR: AIRS2CCF_NRT.006:AIRS.2018.10.18.189.L2.CC_IR.v6.0.31.0.R18291162512.hdf

Granule Long Name: MA_AMSUA_NOAA17_OMF.001:merra.mon_stdv3d_amsua_noaa17_omf.200212_06z.nc

Granule UR: MA_AMSUA_NOAA17_OMF.001:merra.mon_stdv3d_amsua_noaa17_omf.200212_06z.nc

Element Specification

The Granule UR is required (Cardinality: 1)

Model	Element	Type	Constraints	Required?	Cardinality
UMM-G	GranuleUR	String	1 - 250 characters	Yes	1

Metadata Validation and QA/QC

All metadata entering the CMR goes through the below process to ensure metadata quality requirements are met. All records undergo CMR validation before entering the system. The process of QA/QC is slightly different for NASA and non-NASA data providers. Non-NASA providers include interagency and international data providers and are referred to as the International Directory Network (IDN).

title	GCMD Metadata QA/QC

Manual Review
- Check that the quality description is appropriate for the data set.
- Identify errors, discrepancies or omissions.
- Proof all content for conciseness and readability.
Automated Review
- Check for potential broken links.
- Check that the field length is not greater than 12,000 characters.

ARC Priority Matrix

Priority Categorization	Justification
	This element is categorized as highest priority when: The Quality description contains a spelling or grammatical error. The element is being used incorrectly (i.e. for a purpose other than describing data quality). A broken URL is provided in the Quality element.
	This element is categorized as medium priority when: A recommendation is made to change the syntax or content provided the Quality element to improve readability.
	This element is categorized as low priority when: A URL provided in the Quality element is a re-direct link (this includes re-directs from http to https).
	The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Rules

If novalue is provided, return is "np."
Otherwise, return is "OK."
