School of Engineering Sciences at KTH

Job description

The overall purpose of this 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. Contrails and aviation-induced cloudiness effects on climate change show significant uncertainties since they are subject to meteorological, regional, and seasonal variations.

In this context, the researcher will develop 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. We will make use of Convolutional Neural Networks (CNNs), together with transfer learning from already-existing models, as well as recurrent networks such as Long-Short Terms Memory (LSTM), and generative models such as Generative Adversarial Networks (GANs) and variational autoencoders (VAEs). The methodology will follow two steps: temporal predictions and spatial predictions. Finally, the developed AI-driven models should predict, 24 hours in advance, the climate impact of contrails and aviation-induced cloudiness with 80-90% accuracy.

  • A position at a leading technical university that generates knowledge and skills for a sustainable future
  • Engaged and ambitious colleagues along with a creative, international and dynamic working environment
