Element Description

The File Naming Convention refers to the naming convention of the data set's (Collection's) data files along with a description of the granule file construction.

Best Practices

Convention should be a representation of what "fields" may make up the composite parts of a file name, such as dates and IDs.

Description should be used to describe the meaning of what is in the Convention field.

Examples:

FileNamingConvention/Convention: "ESDT.AYYYYDDD.HHMM.VID.YYYYDDDHHMMSS.Format"

FileNamingConvention/Description: "An example file name is VNP01.A2016202.2200.001.2016203071541.nc"

Element Specification

Abstract FileNamingConvention is not required. Only one Abstract FileNamingConvention may be provided (Cardinality: 0..1)

Model	Element	Type	Constraints	Required?	Cardinality	Notes
UMM-C	FileNamingConvention	Object		No	0..1
UMM-C	FileNamingConvention/Convention	String	1 to 4,000 characters	Yes	1
UMM-C	FileNamingConvention/Description	String	1 to 4,000 characters	No	0..1	Required if OtherIdentifiers/Type is 'Other'

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 there is at least a brief summary of the data.
- Confirm that other URLs link to the appropriate web pages.
- Identify errors, discrepancies or omissions.
- Proof all content for conciseness and readability.
Automated Review
- Check that the field length is not greater than 40,000 characters.
- Check that the field length is at least 1 character.
- Check that the convention field has been populated.

In combination with the Advanced Microwave Sounding Unit (AMSU) and the Humidity Sounder for Brazil (HSB), AIRS constitutes an innovative atmospheric sounding group of visible, infrared, and microwave sensors. The AIRS Carbon Dioxide (CO2) Standard Retrieval Product consists of retrieved estimates of CO2, plus estimates of the errors associated with the retrieval. In contrast to AIRX2RET, the horizontal resolution of this standard product is about 110 km (1x1 degree). An AIRS granule has been set as 6 minutes of data, 15 footprints cross track by 22 lines along track.
