                H = Hemisphere with N for north and S for south
 

DOI Authority

• Field Definition:  The Digital Object Identifier (DOI) Authority provides the infrastructure for the registration and services for a persistent reference. The DOI authority is used along with the DOI Name to view the associated URL for the product.

              Example:
              https://doi.org
 

DOI Name

• Field Definition:  Digital Object Identifier is used to uniquely and permanently identify a dataset. The DOI name is more stable than a URL and is used as a permanent reference for the product. The DOI name can be entered into a DOI Authority system to view the associated URL for the product.

              Values:
              Prefix – 10. 5067 identifies registrant agent that has been assigned for NASA ESDIS.
              Suffix – identifies the data item as assigned and managed by the registrant agent.

              Example:
              10.5067/Community/GLIHT/GLCHMT.001
 

Entity ID

• Field Definition:  This field uniquely identifies the individual G-LiHT scene in EarthExplorer.

               Example:
               GLCHMT_FL_20200311_FIA8_l0s8_CHM.tif
 

Local Granule ID

• Field Definition:  The name of an individual file provided by LP DAAC.
  
    Format:
    DatasetShortname+FlightNameProvided.Format
  
    DatasetShortname = Product Type (GLCHMK)
    FlightNameProvided = File name provided by G-LiHT Science Team
    Format = GeoTIFF (.tif) or KML (.kmz)

                Example:
                GLCHMK_AK_20180731_JBER_3_l0s7_CHM.kmz
 

Version Number

• Field Definition:  The version number of the data set.
