    • A Data-Driven Approach to Categorize Climatic Microenvironments 

      Häb, Kathrin; Middel, Ariane; Ruddell, Benjamin L.; Hagen, Hans (The Eurographics Association, 2016)
      In urban climatology, identifying areas of similar microclimatic conditions helps to relate fine-scale urban morphology variations to their impact on atmospheric surroundings. Mobile transect measurements yield high-resolution ...

    • Evaluation of Volume Representation Networks for Meteorological Ensemble Compression 

      Höhlein, Kevin; Weiss, Sebastian; Necker, Tobias; Weissmann, Martin; Miyoshi, Takemasa; Westermann, Rüdiger (The Eurographics Association, 2022)
      Recent studies have shown that volume scene representation networks constitute powerful means to transform 3D scalar fields into extremely compact representations, from which the initial field samples can be randomly ...

    • An Interactive Approach for Identifying Structure Definitions 

      Mikula, Natalia; Dörffel, Tom; Baum, Daniel; Hege, Hans-Christian (The Eurographics Association and John Wiley & Sons Ltd., 2022)
      Our ability to grasp and understand complex phenomena is essentially based on recognizing structures and relating these to each other. For example, any meteorological description of a weather condition and explanation of ...

    • A New Force Model for Controllable Breaking Waves 

      Brousset, Mathias; Darles, Emmanuelle; Meneveaux, Daniel; Poulin, Pierre; Crespin, Benoît (The Eurographics Association, 2015)
      This paper presents a new method for controlling swells and breaking waves using fluid solvers. With conventional approaches that generate waves by pushing particles with oscillating planes, the resulting waves cannot be ...

    • RedSeaAtlas: A Visual Analytics Tool for Spatio-temporal Multivariate Data of the Red Sea 

      Afzal, Shehzad; Ghani, Sohaib; Tissington, Garth; Langodan, Sabique; Dasari, Hari Prasad; Raitsos, Dionysios; Gittings, John; Jamil, Tahira; Srinivasan, Madhusudhanan; Hoteit, Ibrahim (The Eurographics Association, 2019)
      Interactive visualizations play an essential role in supporting the analysis tasks of ocean and atmospheric scientists working on a variety of simulation models and observational datasets. Designing visual analytics systems ...

    • Revealing Multimodality in Ensemble Weather Prediction 

      Galmiche, Natacha; Hauser, Helwig; Spengler, Thomas; Spensberger, Clemens; Brun, Morten; Blaser, Nello (The Eurographics Association, 2021)
      Ensemble methods are widely used to simulate complex non-linear systems and to estimate forecast uncertainty. However, visualizing and analyzing ensemble data is challenging, in particular when multimodality arises, i.e., ...

    • SkyGAN: Towards Realistic Cloud Imagery for Image Based Lighting 

      Mirbauer, Martin; Rittig, Tobias; Iser, Tomáš; Krivánek, Jaroslav; Šikudová, Elena (The Eurographics Association, 2022)
      Achieving photorealism when rendering virtual scenes in movies or architecture visualizations often depends on providing a realistic illumination and background. Typically, spherical environment maps serve both as a natural ...

    • Smart Modelling of Geologic Stratigraphy Concepts using Sketches 

      Sousa, Mario Costa; Silva, Julio Daniel Machado; Silva, Clarissa Coda Marques Machado; Carvalho, Felipe Moura De; Judice, Sicilia; Rahman, Fazilatur; Jacquemyn, Carl; Pataki, Margaret E. H.; Hampson, Gary J.; Jackson, Matthew D.; Petrovskyy, Dmytro; Geiger, Sebastian (The Eurographics Association, 2020)
      Several applications of Earth Science require geologically valid interpretation and visualization of complex physical structures in data-poor subsurface environments. Hand-drawn sketches and illustrations are standard ...

    • Spatial Aggregation of Mobile Transect Measurements for the Identification of Climatic Microenvironments 

      Häb, Kathrin; Middel, Ariane; Ruddell, Benjamin L.; Hagen, Hans (The Eurographics Association, 2015)
      Mobile transect measurements retrieve high-resolution observations revealing the spatial variation of atmospheric properties throughout an urban landscape. A sensor platform is moved through a study site with varying urban ...

    • The State of the Art in Visual Analysis Approaches for Ocean and Atmospheric Datasets 

      Afzal, Shehzad; Hittawe, Mohamad Mazen; Ghani, Sohaib; Jamil, Tahira; Knio, Omar; Hadwiger, Markus; Hoteit, Ibrahim (The Eurographics Association and John Wiley & Sons Ltd., 2019)
      The analysis of ocean and atmospheric datasets offers a unique set of challenges to scientists working in different application areas. These challenges include dealing with extremely large volumes of multidimensional data, ...

    • Using K-Means Clustering for a Spatial Analysis of Multivariate and Time-Varying Microclimate Data 

      Häb, Kathrin; Middel, Ariane; Hagen, Hans (The Eurographics Association, 2013)
      In this study, we propose a k-means clustering algorithm combined with glyph-based encoding method to analyze the spatial distribution and dependence of multivariate, time-varying 3D microclimate data. We obtained five ...

    • Visual Analytics of the Hydrodynamic Flux for Coastal Flooding Prediction and Management 

      George, R. L. S. F.; Robins, P.; Davies, A. G.; Roberts, J. C. (The Eurographics Association, 2013)
      Fifty percent of the earth's population lives within 60 kms of the shoreline. So preventing or mitigating against coastal or estuary flooding is important, especially because of the predicted sea level rise from climate ...
