Europeans to build a series of satellites to contribute to the global weather watch

On 7 December 1999, the Director General of the European Space Agency (ESA), Antonio Rodotà, together
with the Director of the European Organisation for the Exploitation of Meteorological Satellites
(EUMETSAT), Dr. Tillmann Mohr, will sign a contract with Matra Marconi Space for the development and
production of a series of three Metop satellites.

Metop is the first European polar orbiting satellite dedicated to operational meteorology and climate
monitoring. The first spacecraft of the series is scheduled for launch in 2003. The satellite will orbit at
approximately 840 km, at a much lower altitude than the geostationary Meteosat weather satellites which are
placed in
equatorial orbit at approximately 36.000 km. The Meteosat family, also developed by ESA and now owned and
operated by EUMETSAT,
has been in space since the late 1970s. They will soon be replaced by Meteosat Second Generation. The Metop
satellites will provide complementary sounding and imagery data, with a coverage of most of the globe every

Designed by Matra Marconi Space of France, together with a
pan-European industrial consortium which includes, among others, DaimlerChrysler Aerospace of Germany,
Matra Marconi Space of the United Kingdom, and Alenia Aerospazio of Italy, the Metop satellites are based on a
platform derived from the ESA’s Envisat and CNES’s SPOT-5 platforms, both scheduled for launch in 2001.

Metop, which has a mass of 4.5 tonnes, carries twelve instruments which will provide highly valuable
information for meteorologists as well as Earth Science researchers. In addition to a suite of
established instruments provided by the US National Oceanic and
Atmospheric Administration, an advanced Infrared Atmospheric
Sounding Interferometer (IASI) is being developed in Europe which will significantly enhance the
measurement capabilities compared with existing polar satellites. Another “first” is a sounder based on the
occultation of GPS radio signals by the atmosphere, the GRAS instrument, being developed by ESA. Metop will
also carry a
five-channel Microwave Humidity Sounder (MHS), directly procured by EUMETSAT. Other European
instruments are new to operational
use, but have been used with great success by weather centres since they were flown on ESA’s ERS satellites.
Developed by ESA, the
Advanced Scatterometer (ASCAT) instrument will provide key
information about the winds over the ocean surface and the improved Global Ozone Monitoring instrument
(GOME-2) measures the ozone
content of the atmosphere. Overall, the Metop data are expected to provide critical information for the
improvement of Numerical
Weather Prediction systems.

Metop forms part of the EUMETSAT Polar System, which in turn
constitutes the European contribution to an International Joint Polar System (IJPS) operated together with
the United States.

Note to Editors:


The European Space Agency has 14 Member States (Austria, Belgium, Denmark, Finland, France, Germany,
Ireland, Italy, the Netherlands, Norway, Spain, Sweden, Switzerland and the United Kingdom). Its
purpose is to provide for and promote, for exclusively peaceful
purposes, cooperation among European States in space research and technology and their space applications
with a view to their being used for scientific purposes and for space applications systems.

EUMETSAT is an intergovernmental organisation that establishes and maintains operational meteorological
satellites for 17 European
States (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, the Netherlands,
Norway, Portugal, Spain, Sweden, Switzerland, Turkey and the United Kingdom). From July 1999
EUMETSAT also has two Cooperating States, the Republic of Slovakia and the Republic of Hungary). The images
and data from Meteosat
make a significant contribution to weather forecasting throughout Europe and neighbouring continents.

METOP: the roles of ESA and EUMETSAT

The ESA Metop Programme includes the design and development of
the prototype satellite through a joint team provided by the two organisations.

In addition to the coordination of user requirements and specification of the overall system, the EUMETSAT
Polar System (EPS) Programme includes the procurement of the two recurring satellite models, the launch
of all three satellites, the development of a ground segment and the operation of the complete system over the
14 year programme lifetime.
