Subject: DEMETER Workshop
Workshop on the microsatellite DEMETER
First Announcement
----------------------------------
The micro-satellite DEMETER
The micro-satellite DEMETER (Detection of Electro-Magnetic Emissions
Transmitted from Earthquake Regions) is a low-altitude satellite (< 800
km) with a nearly polar orbit. It will be the first scientific
micro-satellite launched by CNES, the French National Space Agency. The
expected launch date is mid-2001. The main scientific objectives of this
project are related to the investigation of ionospheric perturbations due
to seismic activity, and to the global study of the Earth electromagnetic
environment. The payload of DEMETER is composed of several sensors
associated to a data processing unit and a large memory in order to record
the information all around the Earth independently from a telemetry station.
DEMETER will measure electromagnetic waves from DC up to 4 MHz, and plasma
parameters. There are two modes:
- a survey mode to record low bit rate data all around the Earth,
- a burst mode to record high bit rate data above seismic regions shown
in a map which is available on request.
The duration of the mission is two years.
Workshop purposes
This workshop will focus on points related to the scientific objectives of
DEMETER:
- First the workshop will provide a forum to describe new results in
theory and ground or satellite observations of exitation of the
ionosphere by seismic or tectonic processes, either before or after
quakes and volcanic eruptions.
- Second, the workshop will discuss methods concerning statistical analysis
of data recorded by a satellite or by another experiment, and which are
correlated to specific events.
- Third, this workshop will bring together various groups of experimenters
who will perform ground-based measurements close to seismic regions at the
same time as DEMETER will be operating. These measurements may concern DC
fields, electromagnetic noise in various frequency bands, ionospheric
parameters, optical parameters,.... Contributions concerning Total
Electron Content measurements with satellites are also especially
encouraged.
- Fourth, the workshop will concern topics associated to the global
electromagnetic environment of the Earth. This includes space weather,
radio-communications, and particularly the ionospheric perturbations due
to man-made activities.
Workshop Location
The workshop will be held either in Paris or in Orleans (Orleans is located
within 1 hour from Paris). The final location will be given in the
second Announcement.
Dates
The workshop is planned to be on July 15-16, 1999 (just before the IUGG
meeting in Birmingham, July 18-30).
Pre-registration no later than 31 January 1999.
The second announcement will be at the end of February 1999.
Abstracts are due before end of April 1999.
