EMRP-ENV04: Traceable radiometry for remote measurement of climate parameters
LCM, LNE/CNAM, 29 avenue Roger Hennequin, 78197 TRAPPES, France
Remote sensing of the Earth from space, utilising the full electromagnetic spectrum, is the only means of obtaining the global data needed to underpin climate change research and provide the knowledge to enable policy makers to adopt appropriate mitigation and adaptation strategies. In some cases changes of a few tenths of a percent per decade are required relying on measurands that it is currently only possible to carry out NMIs (National Metrology Institute) laboratories at similar levels of uncertainty. A “virtual” centre for EO (Earth Observation) traceability is needed to lead international efforts to develop calibration and validation standards and techniques, pre & post launch, for land, ocean & atmosphere to extend the capabilities of the SI to meet the needs of climate measurement.
