Element Description
The Cloud Cover element provides a measurement, in percentage, of how much of the area of a granule (the EOSDIS data unit) is obscured by clouds. Because the definition of a cloud can vary from one data provider to another, this measurement is generally dataset-specific.
Best Practices
The Cloud Cover element is not a required element. As a result, it is rarely provided. However, in the event that it is provided, please be aware this element varies based on the data provider.

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).
