Resolution 19 (Cg-XVI) on the development of an
architecture for climate monitoring from space
• Decides that an architecture be developed (… ) to provide a
framework for the sustained and coordinated monitoring of
the Earth’s climate from space
• Decides further that the development be undertaken as a
major initiative of the WMO Space Programme, as an
important component of WIGOS, with the support of relevant
technical commissions, and in coordination with satellite
operators, CEOS, CGMS, GCOS, GEO and WCRP.

other co-sponsored observing systems »
– Action 2.1.2 : Collaboration framework to develop the Architecture for
Climate Monitoring from Space
• To set up a badgeless ad-hoc working team (Done)
• To develop a strategy document (Done)
• To define governance procedures and an appropriate body to
implement these procedures (being discussed with CEOS & CGMS)

WIGOS-ICG 18/03/2013
Architecture for Climate Monitoring from Space
in the WIGOS Implementation Plan (2/2)
• As the design of a space-based observing capability and related
ground-segment activities, under Key Activity Area #3 « Design,
Planning and Evolution »
– Proposed Action 3.1.2: To develop the Architecture for Climate Monitoring
from Space focusing on GFCS priorities
• To develop a logical model of the architecture (Done)
• Perform inventory of ECV related products and climate records (Done)
• Evaluate outcome of inventory with reference to logical model
• Evaluate potential contributions of CGMS baseline missions and CEOS
constellations
• Deliver version 0 of physical planning, including capabilities, processes,
gaps and deficiencies in the end-to-end chain
• Action plan to fill the gaps..
• Submission to EC-66, and subsequent iterations

Architecture for Climate Monitoring from Space
• A joint initiative of CEOS,
CGMS and WMO
Strategy towards an Architecture
for Climate Monitoring from Space
• Architecture for climate
monitoring from space is a
foundation for the GFCS
Observation and Monitoring
• Strategy document available
on line
• A printed version is being
prepared by NOAA and ESA

End-to-end Architecture Requirements

Service requirements related to e.g. Agriculture & Food
Security, Water, Health, DRR applications
(4 GFCS priority areas) …
…need translation into product / observation / instrument
requirements:

Product level
 The WIGOS RRR addresses well the « observation
requirements » for geophysical variables but…
 …no systematic process in place for service-level
requirements (e.g., “length of dry spell”, “number of days
with PM10 exposure above 50 μg/m3”)?
 Can current geophysical variable-based approach
capture socio-economic data (e.g., population density;
crop yield; value of infrastructure)?

Outcome of CGMS-40 WG III on architecture

CGMS should evaluate the CGMS baseline in the light
of the architecture strategy and its logical view

Relevant assets will populate space segment part of
the physical architecture as « Potential capabilities to
support ECV products”

Identify gaps from the space segment end
- and scenarios to address them

Conclusions

GFCS partnership should be used to help



The Architecture is an end-to-end approach going beyond
the observation function



Collect climate service requirements and translate these into
product/observation requirements
Some observation requirements go beyond the GCOS ECVs (e.g.,
phenology; socio-economic)
Currently analyzed from the « product » end
Space-based observation capabilities should also be evaluated
from the « sensor » end
Unique role of WMO should be clarified in the future
governance scheme
