The process of quantitatively defining the system responses to known, controlled signal inputs.

The collection of data required to perform calibration of the instrument science data, instrument engineering data, and the spacecraft or platform engineering data. It includes pre-flight and in-flight calibration measurements, calibration equation coefficients derived from calibration software routines, and ground truth data that is to be used in the data calibration processing routine.

An observational study used to acquire targeted observations or samples to support a clearly defined science or research objectives. Also called (or at least related to) what some stakeholders call a Mission, Project, Field Campaign, or Field Investigation. A campaign may be a multi-year program with multiple projects, such as the Arctic-Boreal Vulnerability Experiment (ABoVE), an Earth Ventures Suborbital (EVS) mission, such as Delta-X, or a single project targeting a specific set of measurements, such as the CARbon Atmospheric Flux Experiment (CARAFE).

A set of metadata conventions that were invented for climate and weather forecast data but have since been applied to describe other kinds of Earth Science data, with the intention of promoting the processing and sharing of data.

See Data Set Series

These are metadata elements that describe an entire set of data products or files. Values of collection metadata apply to all of the products in a specific collection. Collections may represent the same release of any given data product, sets of data generated during an experiment, a campaign or an algorithmic test.

A means for enhancing the addressing and access of elements contained in a digital object in the cloud.

CDRs evaluate the integrity of the program integrated design, including its projects and ground systems. CDRs also help meet mission requirements with appropriate margins and acceptable risk within cost and schedule constraints. CDRs also determine if the integrated design is appropriately mature to continue with the final design and fabrication phase.

CERRs evaluate the readiness of the program and its projects to execute a critical event during the flight operations phase of the life cycle.
