Element Description
The Cloud Cover element provides a measurement, in percentage, of how much of the area of a granule (i.e. an individual data file) 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 optional. Please be aware this element may vary based on the data provider, due to differing definitions of what is constituted as a cloud.
Examples:
Cloud Cover: "50"
Cloud Cover: "0"
Cloud Cover: "30.5"
Element Specification
The Cloud Cover element is optional, and may not be repeated (Cardinality: 0..1)
Model | Element | Type | Constraints | Required? | Cardinality |
---|---|---|---|---|---|
UMM-G | CloudCover | Number | 0 - 100 | No | 0..1 |
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.
