Measured Parameters

Element Description

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 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. If provided, then the parameter name(s) must be given.

Parameter Name: The name of the measured geophysical parameters represented in the data

QA Stats: The QA Stats sub-elements provide a measure of select data quality statistics associated with the measured parameter. Each of these stats must be expressed as a percentage value between 0 and 100. QA Stats sub-elements include:
- QA Percent Missing Data: The percent of the data that is missing at the granule level
- QA Percent Out of Bounds Data: The percent of the granule data that is out of bounds
- QA Percent Interpolated Data: The percent of the granule data that was interpolated
- QA Percent Cloud Cover: The percent of the granule data covered by clouds; keep in mind that the definition of a cloud can vary from one data provider to another

QA Flags: The QA Flags sub-elements provide science, operational and automatic quality flags associated with the measured parameter. The criteria for passing each QA flag is specified by the data provider. The actual value of the QA flag must be selected from an enumerated list of values, whereas the criteria or explanation of the QA flag can be provided as free text with a maximum text length of 2,048 characters. QA Flag sub-elements include:
- Automatic Quality Flag: Indicates an automated measure of quality of the specified measured parameter based on guidelines set by the data provider.
  - Valid values for Automatic Quality Flag include: "Passed", "Failed", "Suspect", "Undetermined"
- Automatic Quality Flag Explanation: This sub-element details the criteria utilized for determining the automatic quality flag, including thresholds.
- Operational Quality Flag: Indicates an operational measure of quality of the specified measured parameter based on guidelines set by the data provider.
  - Valid values for Operational Quality Flag include: "Passed", "Failed", "Being Investigated", "Not Investigated", "Inferred Passed", "Inferred Failed", "Suspect", "Undetermined"
- Operational Quality Flag Explanation: This sub-element details the criteria utilized for determining the operational quality flag, including thresholds.
- Science Quality Flag: Indicates a measure of science quality of the specified measured parameter based on guidelines set by the data provider.
  - Valid values for Science Quality Flag include: "Passed", "Failed", "Being Investigated", "Not Investigated", "Inferred Passed", "Inferred Failed", "Suspect", "Hold", "Undetermined"
- Science Quality Flag Explanation: Details the criteria utilized for determining the science quality flag.

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: Measured Parameter Names only are provided

Example 2: Select QA Stats and QA Flags for 1 Measured Parameter is provided

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.

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).
