EGU 2014 "Visualization of Earth Science Data"

All areas in Earth Science face the same problem of dealing with larger and larger data sets that needs to be analyzed, visualized and understood. Depending on the application domain and the specific scientific questions to be solved, different visualization strategies and techniques have to be applied.

Visualization Sessions at EGU 2014

Similar to the EGU 2012 and 2013 we will host several sessions dedicated to the visualization of earth science data. Here we invite submissions that demonstrate how to create effective and intuitive visualizations for complex and large earth science data sets. Submissions are encouraged from all geoscientific areas that either show new techniques, best practices or state of the art in earth science data visualization.

In order to group the submissions and our own contributions, we plan to offer three sessions dedicated to different aspects of visualization for earth science data sets:

  • An oral session, dedicated to new techniques and innovative visualization approaches
  • A PICO session, presenting state of the art in earth science data visualization and focusing on the interaction and rendering of large data sets
  • A light-hands on splinter meeting that introduces two free available tools for data visualization


These workshops and sessions are taught and organized by the German Climate Computing Centre (DKRZ), the National Center for Atmospheric Research (NCAR), the University Corporation for Atmospheric Research (UCAR), the Potsdam Institute for Climate Impact Research (PIK), and the University of Reading.


Oral Session "Techniques and Tools for effective Visualization in the Geoscience"


ESSI3.1, Orals: Mon., April 28. 2014, 15:30 - 17:15, Room G1

ESSI3.1, Poster: Mon., April 28. 2014, 17:30 - 19:00, Red Posters


(Jon Blower, Niklas Röber, Mohan Ramamurthy)

Different tasks in visualization require different visualization strategies. Geoscience data presents particular challenges, being typically large, multivariate, multidimensional, time-varying and uncertain. Submissions are encouraged describing new tools, approaches and applications that help scientists to explore their data or to communicate complex results to a wider audience.

PICO Session "State of the Art in Earth Science Data Visualization"

ESSI3.2: Mon., April 28. 2014, 08:30 - 10:00, PICO Spot 1

(Niklas Röber, Michael Böttinger)

For this "PICO only" session, we invite submissions that demonstrate how to create effective visualizations for complex and large earth science data sets. Submissions are encouraged from all geoscientific areas that either show best practices or state of the art in earth science data visualization, or demonstrate efficient techniques that allow an intuitive interaction with large data sets.

Presentations will be given as PICO (Presenting Interactive COntent) on large interactive touch screens.

Splinter Meeting "Visualization Tools - A light hands-on" (public)

SPM1.12: Wed., April 30. 2014, 08:30 - 12:00, Room Y3

(Niklas Röber, Michael Böttinger, Karin Meier-Fleischer, Magnus Heitzler)

This splinter meeting aims at the presentation and demonstration of commonly available visualization tools, which are especially well suited to analyze earth science data sets. Both NCAR/UCAR and DKRZ have many years of experience in the visualization of climate data sets, and the goal of this workshop is to pass on this knowledge to you. We will explain and demonstrate the tools we work with in our daily routine, and show you how to create effective and meaningful visualizations.

The presentation of the software has the character of a light hands-on, that is, you can follow the examples live on your own laptop, but you don't have to. Below you'll find an overview what software will be shown, along instructions for installation and a set of tutorial files. If you are interested to follow the examples on your personal laptop, please install the required tools and tutorial files, and make sure that they run and are installed properly. If you need help with the installation, please contact the persons on the respective websites. The time constraints for both sessions, unfortunately, do not allow us an individual attendance if problems occur during the session.

Registration for this splinter meeting must be done via this website, a registration for the EGU14 conference is mandatory, however. Please enter your name, your affiliation and your email address below:


Splinter Meeting Details

The splinter meeting is divided into two parts. In the first session, NCL is shown and presented in many examples, while in the second session, Paraview is introduced and presented. Both sessions have the character of a light hands-on, which means that you can follow the examples on your own personal laptop. The table below provides links to websites that assist you in the installation of these tools, as well as to the tutorial files which are used during the session. If you need help for the installation, please use the contact information on the respective website.


Part I: NCL

  • NCL (NCAR Command Language)


Part II: Paraview
