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 names must be provided if a data center provider chooses to provide this element.

The following terms are rarely used but

Parameter Name: The name of the measured geophysical parameters represented in the data
QA Stats: Provides a measured of the data quality statistics associated with the data
- Percent Missing Data: Provides the percent of the data that is missing at the granule level
- QA Percent Out of Bounds Data: Provides the percent of the granule data that was out of bounds
- Percent Interpolated Data: Provides the percent of the granule data that was interpolated

Note: all of these elements are given values between 0 and 100.

- Operational Quality Flag:

- Science Quality Flag:

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).
