METEOSAT image data

• Meteosat-5 was the fifth of the first
  generation satellites

• Primary payload is a 3-channel radiometer

• Image data acquired as follows
• full earth disc scanned every 30 minutes
• spectral channels
• 11µm (thermal IR window)
• 6µm (WV absorption)
• 0.7µm (visible wavelengths)
• IR and WV resolution 5km (2500x2500 pixels)
• VIS resolution 2.5km (5000x5000 pixels)

METEOSAT over the Indian Ocean - a brief history

• Request for support received from the
  International
• Indian Ocean Experiment (INDOEX) in 1998

• METEOSAT-5 drifted to 63 degrees east and
  started
• routine imaging 1 July 1998

• Image data supplied to INDOEX data centre for
  the
• intensive field phase from January to May
  1999

• After the end of the intensive field phase
  the EUMETSAT
• Council agreed to extend the operational
  coverage of the
• Indian Ocean area until the end of 2003.
  This service is
• referred to as the Indian Ocean Data
  Coverage (IODC)

The Indian Ocean Experiment (INDOEX)
INDOEX was an international field experiment with
participation from United Kingdom, France,
Germany, India, the Netherlands, Sweden and the
USA.
Its three main objectives were

• To assess the significance of aerosols for
  global radiative
• forcing

• To assess the magnitude of the solar
  absorption at the surface
• and in the troposphere including the ITCZ
  cloud systems

• To assess the role of the ITZC in the
  transport of trace
• species and pollutants and their resultant,
  radiative forcing.

Indian Ocean Data Coverage (IODC) - current status

• Meteosat-5 launched March 1991 - more than
  10 years old

• Located near longitude 63 degrees east

• Orbit and attitude no longer controlled
  (fuel exhausted)

• Orbital inclination ca. 5 degrees and
  increasing

• Direct reception by user stations problematic

• Some data disseminated via Meteosat-7

• Data made available through bilateral agreements

• Other user requirements to access data ?
• if so contact us on ops_at_eumetsat.de

• Normal EUMETSAT data policy applies (data are
  encrypted)

Future plans for IODC

• Extension of IODC operations to end 2005 to be
  requested at EUMETSAT Council June 2002

• IODC could be conducted using Meteosat-6 or
  Meteosat-7

• Beyond 2005 IODC will depend on
• MSG-2 launch
• availability of Indian and/or Russian
  satellite data

• EUMETSAT delegations have requested that IODC
• is continued until alternative data is
  quantitatively equivalent

Meteosat Second Generation - MSG-1 latest news

• Launch
• Target launch date 13 August 2002
• Ariane-5 launcher with active shock damping
  device

• In-orbit storage
• Extension of LEOP to cover in-orbit storage of a
  few weeks

• Commissioning
• Extended check-out period with spacecraft at 10
  degrees west
• Two phases with two GS configurations

• Parallel Operations
• Following the end of commissioning ca. mid 2003
• MSG-1 at zero longitude, METEOSAT-7 at 10
  degrees
• west, METEOSAT-6 at 10 degrees east,
  METEOSAT-5 at
• 63 degrees east
