NEW CHALLENGES IN ENVIRONMENTAL METROLOGY

摘要

An overview is given on metrology for climate observation needs. The focus is put on remote monitoring of the Earth system. Global observation can be carried out terrestrially, seaborne, airborne and from space. It can provide the necessary information to support politics in deciding appropriate climate change mitigation strategies. However, harsh measurement environments in space, air or seaborne applications limit the uncertainty of measurement results currently attainable. In the specific case of climate observation this is often a factor of ten larger than required. The metrological challenges of a reliable earth observation for climate change detection and verification are discussed.
