Like its predecessor, IASI-NG will use a passive infrared sensor to determine temperature and water vapour profiles in the atmosphere, record ocean surface and land temperatures and monitor a vast range of chemical compounds and other key variables for climate research, including greenhouse gases, desert dust and cloud cover.
With its innovative optical configuration, IASI-NG’s spectral resolution and signal-to-noise ratio will be improved by a factor of two. Measurement precision will also be improved (1 K for temperature and 10% for humidity).
More than just a continuation of IASI, the IASI-NG instrument will be a real asset for atmosphere sciences, particularly numerical weather prediction models, atmospheric composition studies and climate research, thanks to its far-reaching engineering and technological innovations. It will be a key element of Europe’s three MetOp-SG-A series weather satellites, scheduled to launch in 2021, 2028 and 2035.
