WMO Commission for Basic Systems
Report on GCOS
Sue Barrell
Vice President, WMO Commission for Basic
Systems (CBS)
Outline
• Role of CBS
• Overview of GCOS-related activities in
CBS
– Including GFCS
• Addressing Actions in IP-10
Role of CBS
• WMO Commission for Basic Systems (CBS) is the
mechanism through which Members contribute
expertise related to:
– development, implementation and operation of integrated
systems
• for observing, data processing, data communication and data
management,
– provision of public weather services,
– in response to requirements of all WMO Programmes and
opportunities provided by technological developments.
• CBS is the lead Technical Commission for:
–
–
–
–
the overall World Weather Watch Programme (WWW),
the WMO Space Programme and
the Public Weather Services Programme, as well as
Implementation of WIS and WIGOS.
• CBS has 313 members from 140 countries, and is the
biggest TC
Rolling Review of Requirements (1)
• RRR process is supported by the database on
observational user requirements and observing
system capabilities
– Principal aim to address extent to which in situ and spacebased systems meet user requirements for observations
– 12 application areas, incl Climate monitoring (GCOS) and
Climate applications (other aspects - addressed by CCl)
– Focus on WMO programmes and co-sponsored programmes
– Benefits all users of WMO observing systems, incl GCOS
•
Database contains information on:
– Technology-free user requirements, by applications area
– Surface- and space-based observing system capabilities
• CBS-MG seeks strategy for evolution and future
hosting of RRR database
RRR (2)
• Recommendation to CBS-Ext (2010) re database
– Distributed approach
– WMO Secretariat to provide overall coordination and to host
the requirements part
– NASA or EUMETSAT to host the space-based observing
system capabilities part
– EUMETNET or JCOMMOPS to host the surface-based
observing system capabilities part
• Key issues to be considered:
–
–
–
–
–
Quality management consistent with WMO Quality Framework
Experts in applications areas to review user requirements
Link capabilities database to WIGOS components database
Roles and responsibilities of various actors
Funding requirements and sources.
Vision for the GOS in 2025
• Realistic observing systems’ projection in future,
capturing expected trends
– responding to user needs, integration, expansion (incl ECVs),
automation, consistency and homogeneity
– including observing systems for Climate
– approved by EC-LXI
• A new Implementation Plan for global observing
systems will be developed in 2015 based on the new
Vision (requested by EC-LXII)
– will include WMO-’owned’ and co-sponsored systems
– input from GCOS and Climate community expected
• CBS-Ext.(2010) will discuss modalities
– to be ready for CBS in 2012.
New CBS Working Structure
(addressing integration, interoperability, optimization)
• New ET-AIR:
– Optimization of global observing systems after
introduction of new generation of humidity sensor
– filling gaps
• New ET-SBRSO:
– focus on quality procedures for new systems, such
as GPS-Met, Wind-Profilers, Weather Radars
– Focus on gaps, including precipitation (QPE)
• New ET-AWS:
– Focus on Climate needs, metadata, classification of
obs systems, implementation issues
• Proposal to CBS-Ext.(2010):
– Rename ET-Evolution of GOS to ET-Evolution of
global observing systems
GSN/GUAN
• GSN/GUAN stations – suitable selection from RBCN special attention by CBS, also support to GFCS
• Rapporteur on GCOS matters to CBS (Matthew
Menne) highlighted the need for improvements in the
exchange of data from the GSN stations;
– Sub-daily temperature, precipitation and other variables
relevant to climate variability and extremes
– Understanding that is telecommunications issue and not
caused by any underlying shortcoming in the observational
practice or by local data policy (may not be essential data by
Res.40)
• Nine CBS Lead Centres for GCOS monitor RBCN (not
only GSN and GUAN), biennium meetings, reports on
the GCOS Website
• Regular update of the national FP for GCOS and
RBCN / list available from GCOS Website
• Harmonization of RBCN and GSN&GUAN list of
stations
GRUAN
• For GRUAN to become part of GOS and WIGOS,
once fully operational, will need integration of GRUAN
into CBS structures.
– CBS and GCOS to address GRUAN Governance,
Programmatic and Procedural structures
• CBS-Ext.(2010) to discuss a mechanism for approval
of observing practices for GRUAN, developed by
GCOS, for inclusion in Manual and Guide for the GOS
(and CIMO Guide)
– Need for ad hoc team (including CIMO and GCOS experts) to
review WMO regulatory material based on Guide to the
GRUAN
– Target submission to CBS-XV (2012) for consideration
Data Continuity
•
Recommendation to CBS-Ext (2010) that steps
should be taken to define and implement a spacebased architecture for climate monitoring,
–
–
–
•
To support gap-free continuity of ECV data record
To account for the different roles and responsibilities of the
respective entities (including R&D and operational space
agencies, and their coordination bodies)
while responding to the essential need for continuous and
sustained operation
Proposed workshop as a first step to develop a full
understanding of the special climate requirement for
continuity and the associated architectural
implications
–
involving representatives of the climate community
(including GCOS, SCOPE-CM), space agencies of CGMS
and/or CEOS, including representatives of the CEOS
Virtual Constellations
CBS contributions to GFCS
•
•
Activity on defining and implementing space-based
architecture for climate monitoring
Vision for the GOS in 2025 represents comprehensive
response to needs for climate monitoring
–
–
•
database of user requirements covers both climate
monitoring (GCOS) and seasonal-to-interannual forecasting,
but additional requirements (if any) for the newly emerging
application of “decadal forecasting” should be considered
GCW and Third Pole requirements will be also addressed
Guidelines and procedures for the transition from
manual to automatic observing stations
–
–
–
taking into account the GCOS Climate Monitoring principles
an important focus for maintaining the climate integrity of
networks
Joint work with CIMO – Guidelines will be published early
next year
Other GCOS/IP-10 related activities
• Many actions from IP-10 addressed in above activities
• Integral role of QMF as a cornerstone of WIGOS –
aligned to GCOS Climate Monitoring Principles (A4)
• Request for distribution of water vapour data (A12)
from national networks is an issue of data policy.
– Also applies to other communities request for all kind of
national data to be distributed on GTS (like weather radar
data, windprofiler data, GNSS data , precipitation
measurements etc.).
– Several IOS expert teams addressing this issue.
• Meta data exchange (A18) is being addressed,
including by ET-AWS
– Central importance in the WIS and WIGOS activities
• Ocean metadata standard (O33) jointly with
IODE/JCOMM
– Concern target may be too ambitious
WIGOS and WIS
• CBS lead commission in the implementation of
WIS and WIGOS
• Collaborating with co-sponsors of partner
observing systems
• Addressed in other presentations
