This need has been enhanced with the emergence of new commercial satellite operators to ensure that users have a transparent and fair means to judge the adequacy of data products to meet their needs.  \nThe Committee on Earth Observation Satellites (CEOS) Working Group Cal/Val (WGCV) has put in place a framework to assess the maturity and compliance of a “Cal/Val reference measurement” in terms of a set of community-agreed criteria (CEOS-FRM quality). The assessment process is based on a Maturity Matrix that provides a visual assessment of the state of any FRM against each of a set of given criteria, making visible where it is mature and where evolution and effort are still needed.  \nCEOS FRMs Maturity Matrix  \nClass A –Where the measurement fully meets all the criteria necessary to be considered an FRM for a particular class of instrument and measurand.  \nClass B –Where the measurement meets many of the key criteria and has a path towards meeting the Class A status in the near term.  \nClass C –Meets or has some clear path towards achieving the criteria needed to reach a higher class and provides some clear value to the validation of a class of satellite instruments/measurands.  \nClass D – Is a relatively basic adherence to the FRM criteria but there is a strategy and aspiration to progress towards a higher class. This can be considered an entry level class for those starting out on developing an FRM.  \nThe mandatory defining characteristics for CEOS-FRMs are:  \n1. Traceability-FRMs should have documented evidence of their traceability to a community agreed reference, ideally tied to the International System of units, SI.  \n2. Independence from satellite under test-FRMs are independent from the satellite (under-comparison) geophysical retrieval process.  \n3. Uncertainty budget-A comprehensive uncertainty budget for all instruments used in deriving FRM of a particular measurand, including any transformation of the measurand to match that of the satellite product, is available and maintained.  \n4. Documented protocols-FRM protocols, procedures and community-wide quality management practices (measurement, processing, archive, documents, etc.) are defined, published and adhered to by FRM instrument deployments and usages.  \n5. Accessibility-FRM data, including metadata and documentation of processing, are accessible to other researchers allowing independent verification of processing systems. All data and information should be made available in a timely manner and in a form that is readily utilisable by a satellite operator.  \n6. Representativeness-FRM data allow the determination of the on-orbit uncertainty characteristics of satellite geophysical measurements via independent validation activities. It thus requires that the degree of representativeness of the FRM to that of the satellite observation and/or associated retrieval as well as the satellite to FRM comparison process needs to be documented and the uncertainty assessed.  \n7. Adequacy of uncertainty-The uncertainty of the FRM measurements, includingthe comparison process, must be commensurate with the requirements of the class of satellite/instrument/measurand they are specified to support.  \n8. Utility (Return on Investment)-FRM data are designed to apply to a class of satellite missions (several). They should not be mission-specific.  \nPilots for CEOS FRMs Maturity Matrix Assessment:  \n• PGN (Pandonia Global Network) - Stefano Casadio (Serco)  \n• RadCalNet (Radiometric Calibration Network) -Marc Bouvet (ESA/ESTEC)  \n• ICOS (Integrated Carbon Observation System – Ecosystem Component) - Fabrizio Niro (Serco)  \n• FRM4DOAS (Ground-Base","cbCaik19dNsKzImK","https://ap.wps.com/l/cbCaik19dNsKzImK","pdf",1831329,"English","# FRMs Assessment Framework\n## FRMs Definition\n## CEOS-FRM Quality and Assessment Process\n## CEOS FRMs Maturity Matrix\n## CEOS-FRMs Defining Characteristics\n## Pilots for CEOS FRMs Maturity Matrix Assessment","[{\"question\":\"What is the purpose of the CEOS Fiducial Reference Measurements (FRMs) assessment framework?\",\"answer\":\"It provides a community-agreed way to judge the maturity and compliance of a “Cal/Val reference measurement” for post-launch calibration and validation of Earth Observation satellite missions.\"},{\"question\":\"How does the framework assess an FRM’s maturity?\",\"answer\":\"It uses a Maturity Matrix that visually maps the FRM state against a set of community-agreed criteria (CEOS-FRM quality), showing both maturity and remaining gaps.\"},{\"question\":\"What are the mandatory defining characteristics of CEOS-FRMs?\",\"answer\":\"They include traceability, independence from the satellite under test, a comprehensive uncertainty budget, documented protocols and quality management, accessibility of data and documentation, representativeness, adequacy of uncertainty to class requirements, and utility beyond specific missions.\"}]","CEOS Fiducial Reference Measurements (FRMs) Assessment Framework | PDF",1788560427]
