Envisat Mipas is ten years old  

The European Space Agency (Esa), the Cnr-Institute of Applied Physics (Cnr-Ifac) and the Karlsruhe Institute of Technology (Kit) are organizing a workshop to celebrate the tenth  anniversary of the Mipas (Michelson Interferometer for Passive Atmospheric Sounding) experiment on the Envisat satellite. The meeting will be held at the Cnr Research Area of Florence (via Madonna del Piano, 10), in Sesto Fiorentino, next February 29.

Launched in 2002 Envisat was planned to last for five years. After ten years the satellite and its ten instruments are still working. It is the largest Earth Observation spacecraft ever built. It carries ten sophisticated optical and radar instruments to provide continuous observation and monitoring of the Earth's land, atmosphere, oceans and ice caps. Envisat data provide information on the Earth system and insights into processes contributing to its changes. Mipas is a Fourier transform spectrometer for the measurement of atmospheric emission spectra at the Earth's limb. It operates with high spectral resolution in the mid infrared where many of the trace-gases, playing a major role in atmospheric chemistry, have important emission features. Mipas data provide continuous information on the chemistry of the Earth's atmosphere with detailed three dimensional sampling and comprehensive coverage of the main species.

The workshop will be attended by those who have contributed over the years to the Mipas instrument, including the representatives of the industries involved.

Chris Readings, Earth Observation Division Head at Esa at the time when Envisat was devised, will recall the mission conception and development phases, Henri Laur, Envisat Mission Manager, will present the Envisat mission from its launch and its main results, Herbert Fischer, main scientist for the development and operation of a whole family of Mipas experiments, will outline the scientific findings got through this istrument. Bruno Carli, finally, chair of the workshop, coordinator of Mipas Expert Support Laboratory and Quality Working Group and researcher at Cnr-Ifac, will report on the technical achievements of the experiment. The event is open to the public and the English language will be used. Further information will be found at the link www.ifac.cnr.it/retrieval/mipas_10_years.html.
