Further metrology for earth observation and climate: 1/09/2017 to 31/08/2020
A big limitation to providing confident guidance to policymakers on suitable actions to mitigate or adapt to climate change has been the performance of forecast modelling and the quality of the data that these models were built upon. Remote sensing from space was the main source of such data but the buffeting of launch and harshness the space environment limited the potential accuracy and traceability of such data provided by satellite sensors.
The EMPIR project 19ENV07 MetEOC-4 is building on this work.
This EMPIR project applied results from the EMRP projects ENV04 Met-EOC1 and ENV53 Met-EOC2 to improve pre- and post-launch calibration and remote climate sensor validation processes by improving the usability of standards in space and ground-based test sites.
The project also established a method for assigning quality metrics to climate data – which will improve the reliability of evidence for the scale and timescale of climate change, and support mitigation and adaptation strategies.
This project supported earth observation and climate change communities to have access to robust information and advice to support decision-making on mitigation and adaptation strategies facilitated by:
- Upgraded instrument performance
- Fit for purpose data on effectiveness of carbon sinks
- Harmonised methods to identify and quantify trends in long term climate data records (CDRs)
- Improved awareness and consistency on the use and interpretation of ‘uncertainty’
- Providing a focal point for advice on metrology aspects of climate data, in coordination with the European Metrology Network (EMN) for Climate and Ocean Observation
- Internationally coordinated test-sites
- Raised profile of pre-and post-launch calibration and validation (Cal/Val) and traceability
- More efficient and accurate transfer standards
