Element Description

The Input Granules element provides identification of other granule(s) that were used to generate the granule.

Best Practices

The Input Granules element can be used to identify other granule(s) (i.e. data files) that were used to generate the granule data. For instance, this could be used to specify a granule from a lower level data product that was used to generate the granule. For fusion products, this element can be used to list the granules which were fused together to create the resulting granule. Providing Input Granules is optional, but can be leveraged to clearly identify inputs to the file being described (when applicable). It is recommended that the Granule UR, or another unique granule identifier, be used to specify the input granule.

Examples:

Example 1: A level 2 MODIS granule with UR "MOD09.A2019105.0045.006.2019106025523.hdf" provides atmospherically corrected surface reflectance. The granule was generated by processing the following level 1B input granule:

Example 2: A Digital Elevation Model (DEM), a land use/ land cover file, and a land surface temperature file were fused together to create a data file containing all 3 properties:

Input Granule: MOD021KM.A2019105.0045.006.2019105134947.hdf

Input Granule: DEM_feb01_srtm_30m.tif

Input Granule: landsat7_03072019_123456_landclass_30m.tif

Input Granule: landsat7_surfTemp_03072019_123456_30m.tif

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).

Please see the expandable sections below for flowchart details.

ARC Priority Matrix

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The information Input Granule provided is incorrect for the granule..
Yellow = Medium Priority Finding	This element is categorized as medium priority when: Something other than an input granule file is specified in the metadata element (suspected incorrect field usage).
Blue = Low Priority Finding	Not ApplicableNot Applicable
Green = No Findings/Issues	The element is provided and follows all applicable criteria specified in the best practices section above.

ARC Automated Rules

If no value is provided, return is "np."

Otherwise, return is "OK."

Checks

ARC uses the pyQuARC library for automated metadata checks. Please see the pyQuARC GitHub for more information.
