Diana is a meteorological visualisation and production software developed at the Norwegian Meteorological Institute ( Diana is developed for operational use at, and has been used this way since spring 2000. Diana is also used extensively by researchers. It was released as open source under the GNU General Public License (GPL) in May 2006.

Diana features

Combined visualisation of

  • Fields
  • Satellite and radar images
  • Surface observations
  • Trajectories in isosurfaces
  • Weather charts

Separate viewers available for

  • Soundings
  • Vertical cross sections
  • Time series

Editing tools

  • Field modification
  • Drawing of fronts, weather symbols etc.

Other features

  • Highly customable with setup-files
  • Batch version for non-interactive production available

Diana depends on an IT infrastructure, including databases/filesystems for fields, observations and images. There is no acquisition or dissemination tools included.

Programming environment

  • Linux (We use Ubuntu 12.04 and 14.04)
  • C++ (g++)
  • Qt 4 for GUI and window handling, platform independent
  • Mesa3D OpenGL and native drivers for hardware-accelerated 2D graphics
  • a few other Free and Open Source libraries (fonts etc.)
  • connections between applications by Qt QSocket

See Building Metlibs and Diana with Autotools for build instructions and information about dependencies.

The batch version of Diana can be configured to work with a customised version of Qt 4 for use on systems without displays. See Batch Diana on Headless Systems for information about this configuration and instructions for building it.
