| Zusammenfassung | An overview is given on relevant climate observation needs. The main focus is on the use of remote monitoring of the Earth system. Only global observation from space can provide the necessary information to support politics in the development of appropriate mitigation strategies to respond to climate change. The harsh environment of space limits the uncertainty of measurement results currently attainable from remote monitoring. In the specific case of climate this is often a factor of ten larger than required by the community. The necessity for reduced uncertainty has move forward the implementation of metrological traceability by the GEO (Group on Earth Observation) community. As a consequence a Quality Assurance framework (QA4EO) has been established to facilitate interoperability of GEO systems. The metrological challenges of a reliable earth observation for climate change detection and verification are discussed. |
