. . . both satellite and in situ data are
required to better monitor, characterize,
and predict changes in the Earth
system. While in situ measurements
will remain essential and largely
measure what cannot be measured from
satellites, Earth-observation satellites
are the only realistic means to obtain
the necessary global coverage, and with
well-calibrated measurements will
become the single most important
contribution to global observations for
climate.

Ten Years Ago . . .
“The Council recognized that there was an increasing
convergence between research and operational requirements
for the space-based component of the Global Observing
System . . . “
and
“Commitments to address those requirements would allow an
evolution of the space-based component of the GOS that
would help characterize the total Earth and climate system on
a variety of time and space scales. . . “

Motivation
Policy framework in place (UNFCCC, IPCC) and expectations are high
Emerging national and international efforts for climate services will
bring additional demands
Space-agency investments have been considerable, and need to be
leveraged
There are still observational gaps and risks of gaps
Greater coordination is needed in a resource-constrained environment
While contingency measures exist for weather observations, they are
still relatively lacking for climate observations
Long-term and sustained provision of observations will require
additional resources and messages need to be clearer

Coordination
WMO OMM
•
More coordination is needed for each
functional component
•
There is no shortage of coordination
mechanisms
•
Need to leverage existing coordination
mechanisms rather than create new
mechanisms
WMO OMM
Summary
•
Both R&D and operational entities are needed for climate
monitoring – many policy makers don’t know there’s a
difference
•
Key elements or building blocks are in place for improved
sustainability and delivery of climate observations and
products – must leverage existing efforts
•
More coordination and cooperation is needed – recognizing
different, but complementary roles and responsibilities
