 An SI-Traceable Space-based Climate Observing System

hosted by the UK Space Agency at National Physical Laboratory, London, UK, September 9-11, 2019


Recent years have seen an increasing urgency from international coordinating bodies such as CEOS, WMO-GSICS, GCOS, climate researchers, and policy makers to establish a space-based climate observing system capable of unambiguously monitoring indicators of change in the Earth’s climate, as needed for international mitigation strategies such as the 2015 Paris climate accord. Such an observing system requires the combined and coordinated efforts of the world’s space agencies. To deliver data that can be considered unequivocal on decadal timescales, facilitating policy makers to make decisions in a timely manner, requires improvements to heritage, existing, and in-development space assets. In particular, observations spanning the electromagnetic spectrum from the near-UV to microwave need to be of sufficient accuracy and duration, traceable to the International System of Units (SI), and sampled to ensure global representation in order to detect change in as short a timescale as possible. The harshness of launch and the space environment has to date limited any satellite mission’s ability to robustly demonstrate SI traceability on-orbit at the accuracy and confidence levels needed. An order of magnitude improvement is typically required for robust climate observations.

Although not as demanding in terms of long-term accuracies, implementing such a system also facilitates improvements to operational applications, particularly where data harmonisation enables ‘information on-demand’ for a wider range of applications such as health, a sustainable food supply, and pollution.

Bringing together experts from space agencies, industry, academia, and policy makers, the intent of this international workshop is a community strategy to quantify the benefits and consequential specifications of a space-based climate observing system along with a roadmap to implementation. Discussion topics include:

  • Potential scientific and economic benefits,
  • The state-of-the-art in establishing traceability in orbit: current technologies, methods, and missions (e.g. CLARREO and its Pathfinder, TRUTHS, and Chinese and Indian counterparts)
  • New observation and climate-sensitivity detection capabilities and concepts

Stimulated by invited and contributed presentations, the workshop will be structured to ensure ample discussions on all topics. An introductory session will be suitable for a broad audience. This will be followed by more detailed technical discussions, and conclude with a final session focussing on defining observing-system requirements and a draft implementation strategy. The latter will require pre-workshop preparations.

Formal contributions are solicited related to the following themes, which form the basis of sessions in the workshop:

  • Science and societal drivers for the climate and operational communities (including economic benefits)
  • Observations and datasets needed (measurements, timescales, and accuracies)
  • Reference calibrations (facilities/targets, approaches, capabilities, and uncertainties)
  • Mission/technologies/concepts under development or conceived (status, technical capabilities)
  • Develop community ‘white paper’ on benefits, needs, and a proposed implementation architecture.

Pre-registration for this open workshop is required for the venue. Please submit a 300- to 500-word abstract  by April 30, 2019 to stating clearly how it addresses the scope and themes of the workshop. All submissions will be reviewed by the Scientific Organizing Committee and selected for oral or more interactive presentation formats. Please add the following to the subject heading of the email 'CEOS WMO-GSICS Workshop abstract submission'.

Scientific Organising Committee: Nigel Fox (NPL), Bruce Wielicki (NASA), Greg Kopp (U.Colorado/LASP), Xiuqing (“Scott”) Hu (CMA), Tim Hewison (EUMETSAT).
