Enhancing Earth Observation

Multi-sensor synergies and AI-driven insight for a resilient, sustainable Europe

Introducing PANORAMA

By harnessing data from next-generation satellite constellations and advancing AI-powered analysis, PANORAMA enables better decision-making in key domains such as climate action, disaster risk reduction, and sustainable development. The project directly supports the European Green Deal and contributes to modernizing environmental and climate services across Europe.

Our approach

At the heart of PANORAMA is the integration of multi-sensor data from the Copernicus Sentinels, MTG, and EPS-SG constellations. The project fuses atmospheric, radiative, and surface-level data using advanced techniques like data assimilation, machine learning, and top-down emissions estimation. These enhanced EO products are tested in real-world pilot applications addressing air quality, weather extremes, floods, and energy forecasting.

Our vision

PANORAMA envisions a future where Earth Observation is seamlessly embedded in European services — from climate and air quality monitoring to energy and emergency response. By making pre-operational tools available via Copernicus DIAS platforms, the project aims to empower researchers, policy makers, and service developers with robust, interoperable, and user-ready applications.

Planned developments

PANORAMA aims to multiply the value of observations by the next generation of Copernicus Sentinels and EUMETSAT MTG and EPS-SG satellite by realising multi-sensor synergies and to provide advanced aerosol products

PANORAMA plans to demonstrate the improved applications on atmospheric composition and NWP (e.g., motion estimation of aerosols & clouds, fast radiative transfer calculations, top-down emission estimations through ML/AI, data assimilation, and new physical parameterisations).

PANORAMA products and applications will be tested and fine-tuned in 6 pilot demonstrators to assess the impact of the new EO data on the representation and prediction of extreme weather, floods, energy, and air pollution.

Multi-Platform Synergy developments - Data Fusions

Visible + TIR observations (3MI + IASI): Inversion of 3MI observations (with very high information about aerosol properties in the visible), together with IASI observations (with high sensitivity to coarse particles properties) to provide strongly enhanced aerosol products for a wide range of aerosol particle sizes, from very fine to very coarse, with high significance for desert dust research.

GEO + LEO (FCI + 3MI + TROPOMI+S-5): Inversion of GEO (with high temporal coverage) together with LEO observations (with high sensitivity to detailed aerosol properties), to provide strongly improved products, with detailed aerosol information at high temporal coverage.

UV + spectral + polarization + TIR (TROPOMI +S-5+ 3MI + IASI): The observations in the UV, the spectral observations in the Oxygen band, the polarization observations in the visible, and the observations in the TIR, have substantial sensitivity to the vertical variability of the aerosols. Therefore, their synergy is expected to provide highly reliable estimations of Aerosol Lyer Hight (ALH) and other parameters characterising aerosol vertical variability.

Methodology

combining non-coincident satellite observations using the multi-pixel concept is another novelty to be used in the PANORAMA project.

The multi-pixel GRASP concept implements a statistically optimised retrieval simultaneously for a large group of pixels forming spatial-temporal data segments (Dubovik et al., 2011; 2021). This feature brings additional possibilities for improving the accuracy of retrievals by using known constraints on the inter-pixel variability in space and time of aerosol and surface reflectance parameters. This approach is quite suitable for handling the combination of diverse remote sensing measurements and performing their synergetic retrieval, and will be the core concept in realising deep synergy processing in PANORAMA. In the multi-pixel concept the inverted group of pixels includes observations from different locations and times.

Once a group of different observations is inverted together even if they are not fully co-incident the a priori information about known limitations on time and/or in space variability of the retrieved parameters can be applied rather efficiently. In this respect, the fact that the variabilities of different parameters are very different can be very beneficial once the multi-pixel concept is used. For example, the temporal variability of land surface reflectance is very limited while aerosol properties do not change much within only hours, showtime days. On the other hand, the aerosol properties do not change strongly within kilometres, while the land surface reflectance can be highly spatially heterogeneous, with this concept to be very helpful for synergistic processing of observations from MTG, EPS-SG and Sentinel satellite platforms.

The multi-pixel concept for multi-instrument synergy retrieval has been already realised and tested by studies of  Litvinov et al. (2025): a synergetic multi-instrument retrieval approach was developed for the aerosol and surface properties using combinations of S-3A,B, S-5p and HIMAWARI instruments and it was demonstrated that the combined retrieval brings the improvement in retrieved properties from every sensor. For example, all parameters, including AE and SSA, were retrieved from OLCI and HIMAWARI observations with reasonable accuracy, while each sensor separately cannot provide these parameters.
