Element Description
Note: This page is a draft
This element provides the geophysical parameters that were obtained during data collection. It contains not only the name of the parameters, but it also includes the associated data quality stats and data quality flags. The data quality stats provide information on the measurement of the quality of the data while the data quality flags represent the overall quality assurance levels placed on the granule's parameters.
Best Practices
Measured Parameters is an optional element; however, at bare minimum, the parameter name(s) must be provided if a data center chooses to provide this element.
The following terms are rarely provided but
- QA Stats:
- Percent Missing Data:
- QA Percent Out of Bounds Data:
- Percent Interpolated Data:
- QA Flags:
- Automatic Quality Flag:
- Automatic Quality Flag Explanation:
- Operational Quality Flag:
- Operational Quality Flag Explanation:
- Science Quality Flag:
- Science Quality Flag Explanation:
Examples:
MeasuredParamaters/ParameterName: "BIOMASS", "FORESTS", "CROWN", "PLANT CHARACTERISTICS", "VEGETATION SPECIES"
Element Specification
The Measured Parameters element is optional. (Cardinality: 0..*) If measured parameters are provided, the parameter name(s) are required.

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).
