EGU 2013 – SPM 2.12 – Splinter Meeting "Visualization Tools - A light hands-on"

An effective visualization and analysis of data becomes increasingly more important with the growing sizes of data sets. This is especially true for the earth and climate research communities, who produce large amounts of data which need to be analyzed and understood.
Apr 10, 2013 from 03:30 PM to 07:30 PM (Europe/Berlin / UTC200)

SPM 2.12 (April 10, 15:30–19:00 in Room Y3)

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.

This splinter meeting is taught and organized by the German Climate Computing Centre (DKRZ), the Max-Planck-Institute for Meteorology (MPI-M), the National Center for Atmospheric Research (NCAR), and the University Corporation for Atmospheric Research (UCAR).



The room size for this splinter meeting is only 60 persons, therefore we ask everyone who would like to attend to register for this splinter meeting on this website. Please enter your name, your affiliation and your email address. First come, first serve.

If you have been registered and can not attend anymore, please notify us, so we can inform others who might be interested.


Workshop Overview

The splinter meeting is divided into two parts. In the first session, software that is developed and used by NCAR and UCAR is shown, while in the second session, software that is employed at DKRZ is 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.
