The Measured Parameters element provides the geophysical parameters that were obtained during data collection. It contains the name of the parameters with the option to provide associated data quality statistics and data quality flags. The data quality statistics 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.
Measured Parameters is an optional element. If provided, then the parameter name(s) must be given.
Valid values for Operational Quality Flag include: "Passed", "Failed", "Being Investigated", "Not Investigated", "Inferred Passed", "Inferred Failed", "Suspect", "Undetermined"
Providing all of the aforementioned sub-elements is completely optional; however, if a data provider chooses to provide any QA Stats or QA flags information, at least one sub-element from its respective category must be provided.
Examples:
Example 1: Only Measured Parameter Names are provided | Example 2: One Measured Parameter is provided along with select QA Stats and QA Flags for the parameter |
---|---|
Parameter Name: VEGETATION SPECIES Parameter Name: BIOMASS Parameter Name: DIAMETER AT BREAST HEIGHT Parameter Name: FOREST TYPE | Parameter Name: PRECIPITATION AMOUNT QA Stats: QA Percent Missing Data: 5 QA Percent Interpolated Data: 55 QA Percent Cloud Cover: 0 QA Flags: Automatic Quality Flag: Passed Automatic Quality Flag Explanation: Indicates whether data were successfully processed. Absence of error messages during data processing is considered passed. Presence of error messages during data processing will label the data suspect. Science Quality Flag: Inferred Passed Science Quality Flag Explanation: The data in this granule has passed preliminary quality tests. Please refer to the user's guide for further details regarding data accuracy, validation, and limitations for use. |
The Measured Parameters element is optional, and may be repeated (Cardinality: 0..*). If provided, the Parameter Name is required.

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.
