Proposal for infrared atmospheric sounding interferometer on-board data compression

The Infrared Atmospheric Sounding Interferometer (IASI) system provides infrared soundings of moisture and temperature profiles, as well as soundings of chemical components. These measurements play a key role in atmospheric chemistry, global change and climate monitoring. The instrument, developed b...
