Abstract
Modern satellite-based Earth observation measurements demand long-term data records that span multiple missions with reduced uncertainties. SI-traceability and robust uncertainty analyses are key aspects to meeting these demanding requirements. In this presentation we report on the activities of the CCPR-WG-SP TG17, an international task force created within the Bureau International des Poids et Mesures (BIPM) to provide a consistent and coordinated response from the National Metrology Institute (NMI) radiometry community to the needs of the satellite-observation communities.
The BIPM is the international organization through which National Metrology Institutes work together on matters related to metrology. Within the BIPM, the Consultative Committee on Photometry and Radiometry (CCPR) conducts activities concerning measurement standards for photometric and radiometric quantities, development of absolute radiometry, and provides advice on matters concerned with radiometry and photometry. In 2024 the CCPR formed CCPR-WG-SP TG17 to provide a consistent and coordinated response from the NMI radiometry community to the needs of the satellite remote sensing communities.
This talk will report the activities of the CCPR-WG-SP TG17, with opportunity for stakeholders in the audience to provide input. Topics discussed will include relevant activities that are performed at multiple NMI’s, such as providing traceability to the SI for lunar irradiance measurements; activities that are currently available at one or a few NMI’s, such as SI-traceable, far-infrared measurements; and improving communication between the NMI community and the satellite community through discussions of SI-traceability, uncertainty analyses, and terminology.
