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

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 OceanAtmosphere 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.
ICOADS Improvements in 1930s
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
Enabling Mechanisms
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
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
presentation
Use CLIMAR-III to promote marine indices, with a
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
