Forthcoming Meeting and workshop Xiuqing (Scott) Hu GRWG Chair

Forthcoming meeting and Workshops 1. the Joint EUMETSAT/NOAA Satellite Conference has a GSICS user workshop 2. An SI-Traceable Space-based Climate Observing System Workshop(CEOS, WMO-GSICS), NPL, UK, Sep 9 -11, 2019 3. 3 rd Lunar Calibration Workshop (GSICS/IVOS): Where and when is TBD 4. CEOS/GSICS optical space sensor pre-flight calibration and characterisation workshop is postponed to 2020. 5. Potential Workshop about Recalibration/Re-processing for long term Data record dohy 2

3 rd Lunar Calibration Workshop (GSICS/IVOS): • Where and when is TBD, • When: The end of 2019 or first half of 2020 • Candidate hosting: • ESA • NIST Workshop Potential Objectives 1. To share knowledge and expertise on the latest dedicated ground-based lunar observation campaigns, and space-based lunar datasets 2. To share knowledge and expertise in the preparation of lunar irradiance measurements from observations by the instruments to be monitored 3. To work jointly on algorithms to compare and inter-calibrate instruments with lunar observation capabilities dohy 3

An SI-Traceable Space-based Climate Observing System Workshop 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 dohy 4

An SI-Traceable Space-based Climate Observing System Workshop Sponsor by (CEOS, WMO-GSICS), Local host : NPL, UK, Sep 9 -11, 2019 • 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 5 dohy • Pre-registration for this open workshop is required for the venue. Please submit a 300 - to 500 -word abstract online by March 31, 2019 at https: //ceoswmogsicsworkshop. eventbrite. co. uk • Scientific Organising Committee: Nigel Fox (NPL), Bruce Wielicki (NASA), Greg Kopp (U. Colorado/LASP), Xiuqing (“Scott”) Hu (CMA), Tim Hewison (EUMETSAT)

Committee on Earth Observation Satellites WGCV/GSICS pre-flight Cal & Characterisation workshop (optical domain)

• Background • Following previous CEOS workshop at Estec in 2004? Complemented by various Next Meeting regional/national workshops. • Discussions and recommendations from CEOS WGCV IVOS ~2012 timely for new workshop • Parallel interest from GSICS also WGCV- AC-sub group • Agreed plan and outline strategy to hold optical sensor focussed workshop to be held in Europe in 2019 – Now revised to Q 1 2020 • Small task team to initiate process consisting of CEOS and GSICS experts

Agreed Scope • All optical sensors (200 nm to ~50 um) if too wide prioritise solar reflective domain <~2500 nm • Pre-flight satellite • On-board cal systems (pre-flight) • Radiometric/Spectral Cal and characterisation • All aspects impacting e. g. stray light, linearity. Gain…etc • For whom? • Engineers/scientists • Science Pis • To some extent managers/funders • Format? • Primarily Invited presentations followed by discussion? • Call for poster and some short oral on new methods? • Ideally leading to Proceedings/good practises/catalogue of methods • 3 days probably independent 8

s • Planning started for Q 1 2020 • Located in Europe (baseline host CNES Toulouse) • Top level committee CEOS/GSICS has been formed • Establishing Technical organising committee to include industrial participation 9

Reprocessing Activities with GSICS Tim Hewison

GSICS Reprocessing Activities • Coordinate GRWG activities to support: • FCDR generation, NWP Re-Analysis • Reprocessing Sub-Group • • Pan-spectral (UV-VIS-NIR-SWIR-TIR-MW) Independent of existing sub-groups both hyperspectral and multispectral sensors Sessions not to be held in parallel • Initial Workshop to form • 2020? • Before/after GRWG/GDWG meeting? • Best practice
