Expert Team on Climate Change Detection and Indices De Bilt, Netherlands 13-15 May 2008 JCOMM:Perspectives & Contributions 1Val Swail - Environment Canada, Toronto 2Scott Woodruff - NOAA Earth System Research Laboratory, Boulder Elizabeth Kent - National Oceanography Centre, Southampton David Parker - Met Office, Exeter 1Chair – JCOMM Expert Team on Wind Waves and Storm Surge 2Chair – JCOMM Expert Team on Marine Climatology With thanks to Peter Dexter – JCOMM Co-President
JCOMM Concept and Objectives • NWP, climate studies, maritime services, ocean modeling and forecasting, ocean research, all require integrated metocean data and information streams • To address these requirements and realize potential benefits, JCOMM jointly sponsored by WMO and IOC • Combines and benefits from the strengths and expertise of the met. and ocean communities, avoids duplication of effort, integrates existing activities • User oriented, functions at global, regional and national levels • Integrated marine observing, data management and services system; extensive outreach programme • An implementation mechanism for global GOOS and in situ marine component of GOS
Marine Meteorological and Oceanographic Services • JCOMM as the bridge between meteorology and oceanography • Operational oceanography now a reality • Community welfare, socio-economic impacts, hazard mitigation, climate change…. • National and international cooperation essential – IOC, WMO, met and ocean agencies ClimateServices WeatherServices Atmosphere Marine WeatherServices Ocean ClimateServices Ocean Oceanographic Services
How JCOMM Operates • JCOMM is a coordination mechanism only • Implementation of JCOMM programmes by national agencies and institutions • National representation in the work of JCOMM • Single national focal point and coordinator for JCOMM • High level, to coordinate met and ocean communities and ensure priority and budget for JCOMM activities • National members of the Commission • Technical experts to support JCOMM work nationally • Both met and ocean experts • National representation on expert teams and panels • Technical experts in specific fields covered by JCOMM

Perspective on Historical Data • JCOMM Expert Team on Marine Climatology links with International Comprehensive Ocean-Atmosphere Data Set (ICOADS) • Recovery of more data & metadata: key to improving past climatologies, e.g. Recovery of Logbooks And International Marine data (RECLAIM)
Improvements to ICOADS • Many new data sources added to ICOADS focused on data sparse regions and periods.
Background to ETCCDI • Norwich November 2003 – JCOMM presentation to ETCCDMI; responsibility for marine climatology clearly identified as JCOMM responsibility • Beijing November 2005 – CCl recommends JCOMM as full partner in split teams, ETCCDI and ETCM • Tarragona September 2006 – ETCM-I meets; Craig Donlon as JCOMM representative • Exeter November 2006 – JCOMM SCG-III affirms climate services as core activity • Niagara-on-the-Lake November 2006 – ETCCDI-I meets; Val Swail, Liz Kent, Scott Woodruff, Chris Folland JCOMM representatives • CLIMAR-III May 2008 – Marine climate indices invited presentation, Plenary discussion • De Bilt May 2008 - ETCCDI-II meets; David Parker replaces Chris Folland on ETCCDI
WHAT ABOUT INDICES? • JCOMM data offer the possibility for development of a wide variety of marine indices—some of which may be extended much earlier into the historical record than land-based indices • Surface variables • Sub-surface variables • Based on in situ observations, satellite, modelled, blended • Consider not just general circulation indices – compare with existing CCl/CLIVAR land indices • See next talk for details
ICOADS - Critical and critically under-resourced (icoads.noaa.gov ) Proposed new initiative for value-added ICOADS (QC, bias corrections, etc.) JCOMM Expert Teams Wind Waves and Storm Surges Sea Ice Marine Climatology Task Team on the Marine-meteorological and Oceanographic Summaries (TT-MOCS) Task Team on Delayed Mode VOS (TT-DMVOS) Engage expertise within the CLIMAR community to assist in the development and production of marine indices (marineclimatology.net ) Liaise with other groups interested in marine indices such as the AOPC and OOPC Enabling Mechanisms
WAY FORWARD • Investigate how to expand the range of useful and homogeneous climate change indicators available for the ocean including information from both the ocean surface and subsurface • Consider how these might be used in IPCC 5AR (2013) • To engage with other JCOMM Programme Areas as appropriate, and the broader marine climate community in the development, calculation and maintenance of marine indices • Use CLIMAR-III to promote marine indices, with a presentation and Plenary discussion • Report back on progress to the 3rd ETCCDI meeting in May 2008, with a proposal as appropriate for further development of marine climate indices • Aim for presentations at MARCDAT-III (2010) and CLIMAR-IV (2012) that have answers instead of questions
