Refining weather forecasts
This is precisely the area where IASI—the leader of a new generation of optical instruments—is poised to provide a major leap in capability.
IASI will measure infrared spectra in the lower atmosphere (troposphere and lower stratosphere) to establish humidity and temperature profiles twice as accurate as the current generation of spaceborne atmospheric sounders.
IASI will also study greenhouse gases, evaluate ozone levels and collect data on cloud cover.
IASI data will therefore benefit not only weather forecasting but also provide unprecedented information to better understand and monitor climate change.
MetOp and IASI entering the home straight
The 1st IASI instrument has been integrated on the 1st of the MetOp satellites and has completed functional verification tests.
The satellite and its payload, which also includes the French Argos-3 and Sarsat-3 instruments, will be arriving shortly at its launch site in Baikonur, Kazakhstan, where it is scheduled for lift-off atop a Soyuz/ST Fregat launcher in July.
