IASI-NG is an infrared atmospheric sounding instrument designed to fly on the three MetOp-SG satellites of EUMETSAT’s Polar System Second Generation (EPS-SG) being developed under an integrated European Space Agency (ESA) and EUMETSAT team.
IASI-NG offers far superior performance to the first-generation IASI instruments currently operating on the MetOp-A and MetOp-B satellites, which have enabled substantial progress in weather forecasting. With IASI it is now possible to forecast out to 72 hours, making it the most effective weather forecasting instrument in the world.
The new-generation instrument is capable of greatly improved measurement performance, notably for the rarer atmospheric chemical components, thereby ensuring more-accurate forecasts.
The three IASI-NG flight models will be developed and built under a partnership agreement between CNES and EUMETSAT, who are co-funding this project worth more than €230 million. Delivery of the instruments is scheduled for 2018, 2019 and 2020, for launch no earlier than 2021.
