Outline
• Why Climate Monitoring is important
• WMO’s Climate Monitoring activities
• Strategies for developing and improving
Climate Monitoring capabilities
• Discussion

Consider a city running low on drinking
water during a drought
• If you were in
charge of the
city’s long-term
water planning,
what would
you do?

The answer depends on climatic
conditions
• Is this is a once in 200 years drought or a once
in 20 years drought?
• Do long-term data (and model projections)
indicate that droughts of this magnitude are
tending to become more frequent or less
frequent?
• How could you possibly make the right
decision without climate monitoring
information?

Climate Variability and Change
• Impacts numerous societal, economic and
environmental aspects
– Safety, health, food security, tourism, energy, etc.
• Therefore, coping and adapting to these changes
requires understanding their causes, magnitudes
and extent, and to predict their impacts.

Climate Monitoring
• Provides information needed for effective
planning
– As well as for operations to respond to extreme
events

WMO Climate Monitoring Activities

WMO Annual
State of the Global Climate
• Since 1993
• In collaboration with the
WMO Commission for
Climatology
• Authoritative yet simple
– E.g., 13 heavily illustrated
pages

8
WMO also
collaborates on the
larger Bulletin of the
American
Meteorological
Society’s Annual
State of the Climate
• Identifying
potential authors
• Encouraging
interactions

CCl Expert Team on Climate
Monitoring
• Including the use of Satellite and marine data
and products
• Focused on what a
small international
team of experts
could provide any
NMHS trying to
improve their
climate monitoring

10
Expert Team Actions
• Started out by providing information on Climate
Monitoring to WMO Member States.
• Web site with climate monitoring relevant links
• A pamphlet to provide outreach to the community
• Coordinating translation of the BAMS State of the Climate into
Spanish, Chinese, Arabic, French and Russian so more people
could read it
• Publicizing important information
• Such as Guidelines for plant phonological observations
• Writing an article for the WMO Bulletin

By the time the 4 years ended
• Focus evolved towards building and
formalizing interactions
– Enhancing collaboration between major global
climate monitoring centers
– Capacity building collaboration between a satellite
agency and an individual NMHS
• Lesson learned:
– Interactions between scientists is the key first step
towards improving climate monitoring

Strategy for Improving and
Developing Climate Monitoring

13
The Key is Participation
• Until one attempts to monitor the climate it is
difficult to appreciate the many different
things that need to come together in Climate
Monitoring

14
The Importance of Historical Data
• It is the long-term data that allow one to put
current conditions into perspective
– Rescue and digitize old records

15
The Importance of Homogeneity
• Artificial discontinuities in the data can paint
an erroneous climate picture
• Rize, Turkey
• Discontinuity
verified by
metadata
indicating that
station
relocated in
1995

The Importance of Cross-Border
Verification
• Verification by seeing how local conditions fit into
global and regional patterns
• Highlights the
importance of
internationally
sharing data
and
information

17
The Importance of Daily Data
• Can’t globally monitoring daily temperature
extremes
– Yet extremes are more societal relevant than monthly
average
• Heat wave related to increased mortality
• Cold extremes related to agricultural damages
• The same is true for precipitation extremes
– Long-term droughts can be monitored
– But heavy flood producing precipitation events often
can not be monitored globally and put into accurate
historical perspective

18
The Importance of Information, not just
Data
• Even where data are not shared,
information can be
other
• Indices of extremes coordinated by the joint
CCl/CLIVAR/JCOMM Expert Team on Climate Change
Detection and Indices
• A challenge to address in near real-time
• Reporting climate conditions in the annual State
of the Climate report is enhancing cross-border
exchange of information and collaboration on
climate monitoring.
• RCCs could play an important role

Hands-on Workshops are an Effective
Strategy for Development
• Not just listening and talking but doing also
– Photos from Caribbean Climate Extremes workshop

Summary
• Real-time global, regional and local climate
monitoring poses tremendous challenges
• A complex and multifaceted problem
• Only by attempting climate monitoring can a
full appreciation of all the processes come
together
• Regional workshops can jump start that process
• Society needs this information to help guide
adaptation to climate change

Those are our ideas on how to develop
climate monitoring.
What are yours?
