Periodic Reporting for period 1 - E-CONTRAIL (Artificial Neural Networks for the Prediction of Contrails and Aviation Induced Cloudiness)
Période du rapport: 2023-06-01 au 2024-05-31
The overall purpose of E-CONTRAIL project is to develop artificial neural networks (leveraging remote sensing detection methods) for the prediction of the climate impact derived from contrails and aviation-induced cloudiness, contributing, thus, to a better understanding of the non-CO2 impact of aviation on global warming and reducing their associated uncertainties as essential steps towards green aviation.
Specifically, the objectives of E-CONTRAIL are:
• O-1 to develop remote sensing algorithms for the detection of contrails and aviation-induced cloudiness.
• O-2 to quantify the radiative forcing of ice clouds based on remote sensing and radiative transfer methods.
• O-3 to use of deep learning architectures to generate AI models capable of predicting the radiative forcing of contrails based on data-archive numerical weather forecasts and historical traffic
• O-4 to assess the climate impact and develop a visualization tool in a dashboard
Upon successful achievement of the objectives described above, we ambition to provide aviation stakeholders with an early and accurate (thus, reducing the associated uncertainty) prediction of those volumes of airspace with the conditions for large global warming impact due to contrails and aviation-induced cloudiness

We have successfully developed a model capable of detecting contrails in satellite imagery and another for characterizing the evolution of contrails into aviation-induced cloudiness. A nearly 10% improvement in the Dice score for contrail detection models was achieved. Necessary pre- and post-processing steps for optimal performance were outlined. The models were demonstrated to be applicable to European data, though further quantitative validation with MSG/SEVIRI images is pending. Performance is expected to improve with the availability of MTG/FCI data.
We have developed a physics-driven contrail simulation model, including a novel transport equation to address slip mechanisms, simulating the advection-diffusion of ice particles. Persistent contrail propagation is governed by a comprehensive advection-diffusion equation, essential for precise simulations and radiative forcing assessments. While the model requires further refinement, it shows reasonable consistency with methods like CoCiP. Future enhancements will focus on the: 1) Physics Representation: Updating the model to incorporate additional physical processes; 2) Large-Scale Simulation: Reducing computational time for tracking contrails over extensive areas such as Europe, improving algorithm efficiency. The work conducted under this task lays the groundwork for future advancements in understanding and mitigating aviation's climate impact through improved detection and simulation techniques.
