• Providing the material to educate people about

climate change and the contribution attributed to

human activities, thereby enabling individuals to

better understand the impact of their decisions.

In supporting the development of ECVs, EUMETSAT

has striven to place long-term data sets into the hands of

the ultimate user communities. This paper describes the

end-to-end process that will enable EUMETSAT to best

achieve its vision and meet the challenges. It provides

a brief description of each component – space, ground

and end-user segments – for EUMETSAT’s integrated

and coordinated approach to tackling climate monitor-

ing challenges from an operational agency’s perspective.

Space segment

The Meteosat programme is the well-established

European contribution to the ring of operational

geostationary satellites. The first Meteosat satellite was

launched by ESA in 1977. In 1995, EUMETSAT took

over the operation of the Meteosat satellites. EUMETSAT

currently operates two Meteosat satellites of the first

generation (Meteosat-6 and -7) over the Indian Ocean

and two second generation satellites (Meteosat-8 and -9)

over the prime meridian, clearly demonstrating Europe’s

ability to build long-lasting systems that strongly contrib-

ute to fundamental climate data records.

Second generation satellites have much higher capa-

bilities in terms of temporal repeat cycles (15 minutes

compared to 30 minutes for the first generation) and

twelve spectral bands, as compared to only three spec-

tral bands for the first generation Meteosats. The larger

number of spectral bands enables a better observation of

important climate variables, especially those undergo-

ing diurnal cycles. An additional advancement of vital

importance to climate observations is the improved

on-board calibration of the thermal infrared channels

of the Meteosat Second Generation (MSG) satellites.

partner, the European Space Agency (ESA), whose primary objective in

Earth observation is research and development. Whereas ESA develops

new capabilities for monitoring global climatic changes, EUMETSAT

hones that new potential into continuing series of data. These data

respond directly to the requirements of the WMO’s co-sponsored

Global Climate Observing System (GCOS). GCOS has articulated

requirements for Essential Climate Variables (ECVs) in terms of long-

term data records, called Climate Data Records (CDRs). Since its

existence EUMETSAT has responded with dedication and vigour in

providing data for CDRs.

The availability of accurate climate information collected over

decades will benefit mankind at all levels and in a wide range of

areas, including:

• Assistance to policymakers when considering the need for, and

the effects of, actions to mitigate climate change, such as the

Kyoto Protocol

• Monitoring compliance with international obligations related to

climate change

• Assistance to regional and national planners to better assess the

potential impacts of climate change and to thereby select the

most appropriate options for their infrastructure planning

• Supporting initiatives such as Global Monitoring for

Environment and Security (GMES) in its provision of accurate

information for policy-making

• Assistance to the science community in its quest to better

understand the mechanisms of climate change and its potential

impacts

• Support for a better understanding of climate physics, resulting

in better climate projections

• Management of human health risks associated with climate

change, such as the spread of vector-borne diseases and heat stress

• Identification of flood-prone areas and requirements for coastal

protection

• Management of agriculture, fisheries, food production,

freshwater resources and land use

• Risk identification for biodiversity

• Providing the industrial and service sectors with the information

they need to respond efficiently to the challenges of climate change
