Climate: a complex system
Climate variability and change
 For centuries man has tried to change the
weather...but he succeeded at changing
climate
Towards a seamless transition from
weather to climate prediction

2010 ranked globally as the warmest Year on record,
2001-2010 the warmest decade with all individual years are amongst the 11 warmest years on record.
Many Extreme weather and climate events occur each year and need to be monitored and predicted to save lives
2010 recorded an extreme heat wave in Russia, major flooding in Pakistan and Australia and part of West Africa

World Climate Conference-3
Aug 31 – Sept 4, 2009, GENEVA
CCl Management Group meeting, Geneva 18-21 May 2010
WCC-3 High-level Declaration
(approved on 3 September 2009)
DO 1 We, Heads of State and Government, Ministers and Heads of Delegation present at the High-level Segment of the
World Climate Conference-3 (WCC-3) in Geneva, noting the findings of the Expert Segment of the Conference;
OP 1 Decide to establish a Global Framework for Climate Services (hereafter referred to as “the Framework”) to
strengthen production, availability, delivery and application of science-based climate prediction and services;
OP 2 Request the Secretary-General of WMO to convene within four months of the adoption of the Declaration an
intergovernmental meeting of member states of the WMO to approve the terms of reference and to endorse the composition
of a task force of high-level, independent advisors to be appointed by the Secretary-General of the WMO with due
consideration to expertise, geographical and gender balance;
Decide to establish a
Global Framework for Climate Services
OP 3 Decide that the task force will, after wide consultation with governments, partner organizations and relevant
stakeholders, prepare a report, including recommendations on proposed elements of the Framework, to the SecretaryGeneral of WMO within 12 months of the task force being set up. The report should contain findings and proposed next
steps for developing and implementing a Framework. In the development of their report, the taskforce will take into
account the concepts outlined in the annexed Brief Note;
OP 4 Decide further that the report of the task force shall be circulated by the Secretary-General of WMO to Member
States of the WMO for consideration at the next WMO Congress in 2011, with a view to the adoption of a Framework and a
plan for its implementation; and
OP 5 Invite the Secretary-General of WMO to provide the report to relevant organizations, including the UN SecretaryGeneral.

Importance of radiocommunications for
meteorological operation and research
Radiocommunication Services used
for meteorology
• Specific radiocommunication services:
–
–
–
–
Meteorological Aids Service
Meteorological-Satellite Service
Earth Exploration-Satellite Service (passive)
Earth Exploration-Satellite Service (active)
• Joint ITU-WMO Handbook “Use of Radio
Spectrum for Meteorology: Weather, Water and
Climate Monitoring and Prediction”,
– freely available online
http://www.itu.int/pub/R-HDB-45-2008
Radiocommunication Services for
meteorology
• As special systems of generic
radiocommunication services:
– Meteorological weather radars and Windprofiler radars of the Radiolocation Service
• As users of Radiocommunication Services:
– Fixed Service, Mobile Service, etc.
XVI World Meteorological Congress
Maintained Cg XV Resolution 4 that:
• Highlights the crucial importance of RF bands for
meteorological and related environmental operations and
research
• Stresses that some RF bands are a unique natural resource
for passive sensing that deserve absolute protection
• Appeals to ITU and its Administrations to ensure the
absolute protection of the passive sensing RF bands, and to
give due consideration to the WMO requirements for RF
allocations and regulatory provisions
• Complements ITU Resolutions (WRC-07)
– 673 “Radiocommunications use for Earth observation applications”
– 647 “Spectrum management guidelines for emergency and disaster
relief radiocommunication
Monitoring the climate is dependant on radio
frequency
