Plenary 2 – Space Optics in NOAA’s Earth and Solar Observing Systems

Elsayed R. TALAAT – National Oceanic and Atmospheric Administration

The National Oceanic and Atmospheric Administration’s (NOAA) mission is to understand and predict changes in climate, weather, oceans and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources as the Nation’s authoritative environmental intelligence agency.

NOAA’s National Environmental Satellite, Data, and Information Service (NESDIS) supports NOAA’s mission of Science, Service and Stewardship through our satellite missions, data centers, data and information products and services as well as use-inspired science. It is an end- to-end responsibility that underpins NOAA’s value to the Nation. The United States depends on NOAA to provide satellite data and imagery for meteorological and space weather forecasts and emergency services to support continuity of government. NESDIS’ responsibility is to collect and provide the critical satellite Earth and space observations and other essential environmental information needed for disaster preparedness, all hazards response and recovery and the protection of the Nation’s critical infrastructure and natural resources. The 24/7 global coverage provided by NESDIS generates an uninterrupted stream of information and products.

This talk overviews the fleet of environmental satellites that provide critical observations of the Earth and space. It also discusses strategies for NOAA’s future space-based observation architecture and the remote sensing capabilities being considered for low Earth, geostationary, and extended orbits.

Plenary 3 – IASI-NG: when improving our understanding of the Earth atmosphere requires to multiply innovations in an operational meteorological programme

Adrien DESCHAMPS – Program Manager for Atmosphere and Meteorology, CNES

Successor of IASI (Infrared Atmospheric Sounding Interferometer), IASI-NG is currently being developed under the authority of CNES in collaboration with EUMETSAT. More than a single payload, IASI-NG is a complex system that combines an innovative interferometer developed by Airbus Defense and Space and a complex ground segment that includes specific algorithms for the “Level 1” data processing (spectral and radiometric calibration, removal of the instrument function, spike correction…). It will be a major component of the European Polar System – Second Generation that will count six satellites including Metop-SG A. This satellite will embark the first IASI-NG instrument and is expected to be launched end of 2023.

This talk will start by reminding the huge contribution of IASI data in Numerical Weather Prediction services but also for climate studies and atmospheric composition. Then, we will show how the ambitious scientific goals for IASI-NG led to dramatically change the instrumental concept compared to the first generation and to use innovative technologies for different subsystems. Finally, we will give an overview of the on-ground processing and describe the algorithms that have been specifically designed to calibrate the raw spectra and to remove the effects of the instrument before transmission to the end-users.

As a conclusion, the other missions (in orbit or under development) that constitute the atmospheric programme at CNES will be briefly presented and some perspectives for the future of the atmospheric missions (compact instrument for dedicated molecules, use of constellation of nanosatellites, increase of the spatial resolution towards spectral imagery) will be discussed.
