Abstract
Incontrovertible evidence of climate change and the underlying causes is necessary to inform public debate and to guide policy and economic decisions. To affect key societal decisions, this evidence must be obtained from measurements that are irrefutably tied to recognized international measurement standards. The International System of Units (SI) provides the appropriate measurement foundation for this application. The feasibility of achieving this objective and the resulting benefits to long-term climate forecasting are presented. The significant differences between realizing SI-traceability for space-based measurements and for laboratory measurements are detailed. An overview is presented of technological innovations in calibration standards and evolution in measurement approaches that define these new infrared standards. These include calibration blackbodies with built-in temperature standards and redundant sensors that admit new diagnostic tests of measurement uncertainty. An approach to rapid deployment is discussed, along with its resulting data product and benefits for long-term climate forecasting.
