Master Thesis Enter the fascinating world of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and help shape the future through research and innovation! We offer an exciting and inspiring working environment driven by the expertise and curiosity of our 11,000 employees from 100 nations and our unique infrastructure. Together, we develop sustainable technologies and thus contribute to finding solutions to global challenges. Would you like to join us in addressing this major future challenge? Then this is your place! For our Institute of Atmospheric Physics in Oberpfaffenhofen we are looking for a Student in Computer Science, Physics, Meteorology or similar (f/m/x) Thunderstorm Forecasting Using Diffusion Models on Satellite Data What to expect: Thunderstorms are associated with several extreme-weather events (e.g. lightning, heavy rain, hail). As a consequence of climate change, the severity of these events is expected to increase in the future. Spatiotemporally highly resolved short-term predictions of thunderstorms are an essential tool to limit significant social and economic damage.
Short-term forecasting has traditionally been a data-driven field, so naturally, machine learning (ML) models have emerged as promising alternatives to traditional extrapolation-based methods. Current models are based on convolutional neural networks (CNNs), which produce deterministic forecasts. However, weather systems are inherently chaotic, implying the need for probabilistic models to quantify uncertainty. On the other hand, diffusion models (DMs) have become state of the art in generative tasks, particularly in image generation. DMs are designed to produce diverse samples, making them well-suited for tasks where uncertainty needs to be explicitly modeled.
The primary objective of this master thesis is to improve upon current CNN-based thunderstorm forecasting by training DMs on satellite data. Specifically, this project aims to investigate the efficacy of DMs in short-term thunderstorm forecasting and compare their performance to CNNs in terms of predictive accuracy and uncertainty quantification.
What we expect from you:
What we offer: DLR stands for diversity, appreciation and equality for all people. We promote independent work and the individual development of our employees both personally and professionally. To this end, we offer numerous training and development opportunities. Equal opportunities are of particular importance to us, which is why we want to increase the proportion of women in science and management in particular. Applicants with severe disabilities will be given preference if they are qualified. Further information: Starting date: sofort
Duration of contract: 6-9 months Type of employment: Teilzeit Remuneration: Up to German TVöD 5
