INGRID
INGRID is a spaceborne instrument platform developed for high-resolution imaging and spectroscopic studies of Earth and planetary atmospheres. It was conceived through cooperation between major research institutions and agencies to advance remote sensing capabilities, integrating technologies from prior missions and enabling targeted campaigns across polar, temperate, and equatorial regions. The program brought together teams experienced with instruments from missions such as Envisat, Sentinel-2, Landsat 8, Aqua and Terra to produce a compact, versatile payload suitable for constellation deployment.
INGRID combines multispectral imagery, hyperspectral sounding, and active lidar modalities to measure atmospheric composition, aerosol properties, and surface reflectance. The platform leverages heritage from instruments like MODIS, MERIS, OMI, SCIAMACHY, TROPOMI, CALIPSO, and MISR while incorporating advances demonstrated by PRISMA, HISUI, and the Copernicus family. Designed to interface with ground networks such as Global Atmospheric Watch, AERONET, and space infrastructure like the International Space Station, INGRID supports coordinated observations with missions including Suomi NPP, Jason-3, and GRACE-FO.
The INGRID concept emerged from workshops at institutions including European Space Agency, National Aeronautics and Space Administration, Japan Aerospace Exploration Agency, and research centers such as NASA Goddard Space Flight Center, DLR (German Aerospace Center), and CNES. Early feasibility studies referenced techniques used on ERBS, Nimbus-7, and balloon campaigns affiliated with CSIRO and WMO laboratories. Funding and collaborative agreements were negotiated with universities and industrial partners like Thales Alenia Space, Airbus Defence and Space, and OHB SE. Prototype testing drew on facilities at ESTEC, JPL, Ames Research Center, RAL Space, and ISRO test ranges.
INGRID's optical suite centres on a stabilized telescope assembly with a primary aperture derived from designs used on SPOT and PlanetScope platforms, paired with a diffraction-grating hyperspectral module influenced by Hyperion and HICO. The payload includes: - A multispectral imager with bands similar to Landsat 9 and Sentinel-3 instruments for surface characterization. - A hyperspectral sounder providing VNIR-SWIR coverage comparable to EnMAP and PRISMA. - A compact Doppler lidar channel adopting techniques from CALIPSO and research lidar demonstrated by EarthCARE concepts. Avionics derive from flight-proven buses used by VEGA, Soyuz, and Falcon 9 secondary payload programs, with guidance referencing components tested on Proba-3 and CubeSat technology demonstrators. Thermal control uses methods validated on CryoSat and SMOS.
Primary objectives include mapping aerosol optical depth, profiling trace gases such as ozone, nitrogen dioxide, and methane, and retrieving surface bidirectional reflectance factors for land cover and cryosphere studies. Capabilities align with measurement goals established by panels like IPCC, GEOSS, and CEOS, enabling synergy with field campaigns run by groups such as NOAA and EUMETSAT. INGRID supports: - High-spatial-resolution land cover monitoring to complement MODIS and VIIRS records. - Column and profile retrievals to augment datasets from IASI, MLS, and ACE. - Aerosol microphysical parameter estimation coordinated with AERONET ground sites and SAGE occultation measurements.
Operations are planned from a low-inclination sun-synchronous orbit to maximize repeatability and coordination with polar-orbiting constellations including Sentinel-1 and Sentinel-2. The timeline includes integration and environmental testing at ESTEC and CSG, launch on a Vega-C vehicle, early commissioning similar to procedures used by Sentinel-3A, and routine operations managed by mission control centers modeled after ESOC and NHSC. Science campaigns are scheduled in coordination with international exercises such as AeroCom experiments, volcano monitoring linked to Global Volcanism Program alerts, and air quality campaigns aligned with BREATHE, ICARE, and regional observatories.
INGRID adopts processing chains influenced by pipelines used for Sentinel-3, Landsat Collection 2, and MODIS Level-2/Level-3 products. Algorithms draw on retrieval methods published by teams behind TROPOMI, SCIAMACHY, OMPS, and MOPITT, implementing atmospheric correction approaches popularized by 6S and radiative transfer tools from RTTOV and MODTRAN families. Data dissemination leverages services comparable to Copernicus Open Access Hub, NASA Earthdata, and PO.DAAC, with quality control and calibration crosschecks using references such as GOME-2 and ACE-FTS.
INGRID aims to leave a legacy of improved continuity between heritage sensors and next-generation instruments, filling observational gaps for long-term climate records used by bodies like IPCC and WMO. Expected impacts include stronger support for air quality regulation informed by WHO guidelines, enhanced disaster response coordination with UN Office for Disaster Risk Reduction, and contribution to science from institutions such as Universities Space Research Association and national labs. The program also fosters industrial growth across suppliers including Thales Alenia Space and Airbus, while enabling downstream applications for agriculture, forestry, and urban planning linked to initiatives like GEO, ESA Climate Office, and national space agencies.
