From September 29. to October first, 2014, the DKRZ / the CliSAP Climate Visualization Laboratory hosted a 3-day hands-on tutorial workshop on the data analysis and 2D visualization software "NCL", a scripting language developed by the National Center for Atmospheric Research (NCAR).

Content: This is a beginner level workshop which was focused on the use of NCL for the visualization of 2D gridded model or observational data. The tutorial covers the following content:

  • NCL language basics
  • Scalar techniques (XY-, Contour-, Slice-, Bar Chart-plots)
  • Plot layout (Panels, Overlays, Annotations, Maps)
  • Creating animations

More advanced topics, specifically help with visualizing your own data can be covered on the third workshop day.

Prerequisites: Basic Linux/Unix and programming experiences are recommended.

Lecturers: Karin Meier-Fleischer (DKRZ) and Mary Haley (NCAR), supported by Michael Böttinger (DKRZ).
