Timeline

 

Parasol is the second microsatellite in the Myriade series developed by CNES. It is carrying a wide-field imaging radiometer/polarimeter called POLDER (Polarization and Directionality of the Earth’s Reflectances), designed in partnership with the LOA atmospheric optics laboratory in Lille (CNRS-USTL). POLDER is designed to improve our knowledge of the radiative and microphysical properties of clouds and aerosols by measuring the directionality and polarization of light reflected by the Earth-atmosphere system.

Launched by an Ariane 5 G+ from Europe’s spaceport in Kourou, French Guiana, Parasol has embarked on an expected two-year mission, flying in formation with Aqua and Aura (NASA), Calipso (NASA/CNES) and CloudSat (NASA/CSA) as part of the so-called A-Train. These satellites, to be joined later by NASA’s Orbiting Carbon Observatory (OCO) in 2008, will for the first time ever combine a full suite of instruments for observing clouds and aerosols, from passive radiometers to active lidar and radar sounders.

STATUS
  Since November 28, 2007 19:24:20 UTC, Calipso has definitively changed its tilt (pitch from 0,3° to 3°) following tests performed from November 6 to 15, 2006 and from August 21 to September 7 2007.
To insure the best possible footpring overlap, Cloudsat has modified its position with respect to Calipso by moving 5 secondes away ahead of Calipso.
