Element Description

The archive and distribution information main element allows data providers to provide users information of what is available for downloading when they initially looking at a collection. The end users get information such as the average downloadable file size, format, mime type, checksum, etc., an estimate of the collections entire downloadable file size, etc.

Best Practices

Instrument keywords are important for the discovery of data. All relevant instruments should be listed for each dataset, and each instrument listed should be provided under its associated platform. It is preferred that more specific instrument keyword terms be chosen from the KMS when available. For example, if data were collected from the AMSR-E instrument, it is preferred that "AMSR-E" be listed as the instrument as opposed to the more generic "RADIOMETERS" keyword. If a particular instrument keyword is missing from the KMS, it is possible to put in a request to have it added. The KMS is managed by the Global Change Master Directory (GCMD) and new keyword requests may be made through the GCMD Keywords Community Forum.


The Instruments/Technique field is optional. It can be used to further describe the technique utilized by the instrument for data collection. For example, the technique for a laser altimeter instrument on board a satellite could read "Measures the distance of the satellite from the Earth's surface by taking a precise measurement of the time it takes a transmitted laser pulse to hit the ground and then return to the instrument." 

The Instruments/NumberOfInstruments field is optional. It can be used to indicate the number of instruments (i.e. sensors) used on the instrument while acquiring data. For example, the Terra satellite carries the ASTER instrument. The ASTER instrument is made up of 3 instrument subsystems (VNIR, SWIR, and TIR). In this example, the Instruments/NumberOfInstruments field would read "3".

The Instruments/OperationalModes field is optional and may be repeated. This field can be used to specify the mode(s) in which an instrument collects data. For example, the Sentinel-1 satellite collects data in four different modes. If a collection were to contain data acquired in all four modes, the OperationalModes field could be repeated four times and read "Stripmap (SM)", "Interferomic Wide swath (IW)", "Extra-Wide swath (EW)", "Wave (WV)"  


Examples (ShortName > LongName):

SMMR > Scanning Multichannel Microwave Radiometer

OLI > Operational Land Imager

UAVSAR > Uninhabited Aerial Vehicle Synthetic Aperture Radar

LIS > Lightning Imaging Sensor

XPOL > NOAA/ETL X-band Polarimetric Doppler Radar 


Element Specification

Instrument is an optional metadata element, however, it is strongly recommended that it be provided when possible. Multiple Instruments may be listed if necessary (Cardinality: 0..*).

Providing instrument characteristics is optional. An unlimited amount of instrument characteristics may be specified for a particular instrument (Cardinality: 0..*). If instrument characteristics are provided, all 5 sub-fields (Name, Description, DataType, Unit, Value) are required.

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.


  • Manual Review
    • Identify errors, discrepancies or omissions.
    • Verify that all pertinent keywords have been applied.
    • Verify that existing facets and other controlled keyword values are consistent and suitable for the data.
  • Automated Review
    • Check that the field has been populated.
    • Check that the field is populated with a valid value from KMS.
    • Check that the field value is not a duplicate.
    • Check that the field length is not greater than the maximum characters allowed for each sub-element.
    • Check that the field '/Instrument/NumberOfSensors' is an integer value.
  • The specific instrument must be unique within the collection. The uniqueness is established by combining the instrument short name along with its characteristic's name.
  • The instrument short name must match with what is in the KMS.
  • If a granule has an instrument short name in it, it must match to one that is defined in the collection.
  • If removing an instrument from a collection, none of its granules can reference that instrument's short name.

ARC Priority Matrix

Priority CategorizationJustification

This element is categorized as highest priority when:

  • The element is not included at all.
  • The instrument short name tags are provided in the metadata but are left empty.
  • The instrument keyword does not align with the KMS.
    • The instrument keyword does not exist in KMS.
    • A keyword(s) is placed in the incorrect position of the hierarchy (e.g. the instrument short name is placed in the long name field).
    • Keywords from two different KMS hierarchies are listed in the same hierarchy in the metadata (i.e. hierarchies cannot be mixed and matched)
  • Not all relevant instruments are listed.
  • An incorrect instrument is listed.
  • An instrument is listed under the incorrect platform.
  • A recommendation is made to replace a valid instrument with a more specific/appropriate instrument keyword.
  • Please see the Characteristics wiki page for high priority issues related to the Characteristics sub-elements.

This element is categorized as medium priority when:

  • A recommendation is made to add an instrument long name when a long name exists in the KMS.
  • Instruments are provided in an inconsistent manner across related datasets.
  • Please see the Characteristics wiki page for medium priority issues related to the Characteristics sub-elements.

This element is categorized as low priority when:


The element is provided, and follows all applicable criteria specified in the best practices section above.

ARC Automated Checks

  • Instrument Short Name
    • If no value is provided, return is: "This is a required field. Recommend providing at least one Instrument Short Name relevent to this data set. Instrument Short Name is GCMD controlled and should be selected from the following list: https://gcmdservices.gsfc.nasa.gov/static/kms/instruments/instruments.csv?ed_wiki_keywords_page"
    • If the provided value is in the incorrect hierarchy position, return is: "<provided value> is in the incorrect position of the project keyword hierarchy."
    • If the provided value does not conform to GCMD, return is: "<provided value> does not conform to GCMD."
  • Instrument Long Name

    • If no value is provided, return is: "Recommend providing at least one Instrument Long name relevent to this data set. Instrument Long Name is GCMD controlled and should be selected from the following list: https://gcmdservices.gsfc.nasa.gov/static/kms/instruments/instruments.csv?ed_wiki_keywords_page"

    • If the provided value is in the incorrect hierarchy position, return is: "<provided value> is in the incorrect position of the project keyword hierarchy."
    • If the provided value does not conform to GCMD, return is: "<provided value> does not conform to GCMD."

An ID should be provided directly after "eos:EOS_Instrument" in the ISO x-path. This ID corresponds to the instrument and is used to link the instrument information to the associated platform. The ID should be unique within the metadata record.
