Element Description
The Quality metadata element is a free text field which is used to describe the quality of the collection data.
Best Practices
This field may be used to describe any indications of quality of the data. Examples of appropriate element information include: a) a succinct description of the quality of data in the collection; b) quality assurance procedures followed in producing the data in the collection; c) indicators of collection quality or quality flags - both validated or invalidated; d) recognized or potential problems with quality; e) established quality control mechanisms; and 6) established quantitative quality measurements. The Quality element is optional.
Examples:
Quality: "Users are advised that ASTER SWIR data acquired from late April 2008 to the present exhibit anomalous saturation of values and anomalous striping. This effect is also present for some prior acquisition periods. Please refer to the ASTER SWIR User Advisory Document (https://lpdaac.usgs.gov/sites/default/files/public/aster/docs/ASTER_SWIR_User_Advisory_July%2018_08.pdf) for more details."
Quality: "This data has been in extensive use in weather forecasting and atmospheric chemistry research for many years, and has thus been subject to independent review by many scientific experts."

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.
