Dynlib: A library of diagnostics, feature detection algorithms, plotting and convenience functions for dynamic meteorology

Spensberger, Clemens

Dynlib is the library of tools developed within the dynamical meteorology group at the Bjerknes Centre and Geophysical Institute at the University of Bergen. In addition to its use within the group, dynlib is the basis for the MIND the KAP which makes the diagnostics and detection algorithms in dynlib easily applicable to NorESM and NorCPM output.

Comprehensive documentation is included with the source code. An up-to-date compiled version of the documentation is available under

Dynlib has a development history of nearly a decade. During this time, numerous people have contributed to its development with code, bug fixes, bug reports and general feedback. Code contributions are generally acknowledged in the code and documentation of the respective functions. Here, I want to specifically acknowledge and thank for the contributions to the code from Chris Weijenborg, Clio Michel and Angus Munro. In addition I am grateful for reference implementations of the slope-related diagnostics by Lukas Papritz, and of line-feature detections by Gareth Berry, both of which served as a reference for the corresponding functions in dynlib. Dynlib is generally licensed under the CC-BY 4.0 as defined here, but some functions which were incorporated from other libraries are licensed under differing open-source licenses.
