[Webinar Series] When AI meets the sky: All sky imagers – from basic research to energy applications
We are proud to present a webinar on cutting-edge research in atmospheric sciences and cloud observation techniques: When AI meets the sky All sky imagers – from basic research to energy applications will showcase the collaborative efforts of researchers in advancing our understanding of cloud dynamics and their impact on solar radiation prediction.
In this webinar, you will learn about innovative methods for cloud observation and classification, as well as their applications in renewable energy forecasting. Our speakers will present recent developments in image processing, machine learning, and data integration techniques that are revolutionizing the field of atmospheric physics.
Mehdi Ben Slama from Reuniwatt will discuss the latest advancements in cloud type classification using various imaging technologies. He will present the capabilities of all-sky imagers for Atmospheric Science, and findings from Reuniwatt’s our study, “Leveraging Wide-Field of View Imagers to Improve the Instantaneous Cloud Amount Estimates“. In his presentation, he’ll propose novel approaches to estimating multi-layer cloud amounts from a single image.
Emanuele Giovanni Carlo Ogliari from the Department of Energy at Politecnico di Milano will focus on the practical applications of sky imager data in the renewable energy sector, particularly for solar radiation estimation. His presentation will delve into the development of machine learning-based methods for nowcasting global horizontal irradiance 5-15 minutes ahead. He will propose a Machine Learning based method using sequences of infrared images captured by an All-Sky Imager to forecast the Global Horizontal Irradiance on different time horizon. Additionally, exogenous data, as the solar radiation measurement, is encoded in the images through an innovative technique, the Enhanced Convolutional Neural Network (ECNN). Considering the naïve persistence method as a baseline, a clear improvement across the key metrics has been noted with the proposed methodology. A deeper analysis of the results reveals that the proposed models are more accurate than persistence when high fluctuations of solar radiation are experienced.
Prof. Stephanie Fiedler will welcome you and lead you through the event. We will demonstrate how these advanced cloud observation and prediction techniques contribute to more accurate solar radiation forecasts, which are crucial for the stability and efficient management of electric grids.
Join us for this exciting webinar to explore the latest developments in atmospheric sciences and their real-world implications. Our speakers will be available to answer your questions on cloud observation, modeling, and solar radiation prediction.
After this webinar, you will have a better understanding of:

About Universität Heidelberg (www.iup.uni-heidelberg.de)
Established in 1975, the Institute of Environmental Physics at Heidelberg University is one of the most prominent centers for environmental research in Europe. The institute’s research spans four main areas: Atmosphere, Aquatic Systems, Climate, and Simulation and Modeling, and investigates the flow of energy and matter in our environment in order to better understand the Earth’s climate system from the past to the future. The institute’s approach to environmental research focuses on underlying physical principles rather than specific applications, allowing for flexibility in methods and the ability to overcome traditional disciplinary boundaries. Prof. Fiedler’s research group ALIC2E does scientific work on AerosoL In Climate ChangE. Their interest in atmospheric physics has a focus on interactions of atmospheric composition and dynamics from weather to climate scales, seeking answers to questions on the role of aerosols and circulation for the regional climate, including links to the hydrological cycle, interactions with land processes, and impacts on renewable power production.
