During my work, I created some additions to models or useful interfaces, which I decided to share with anyone interested.
So I started some GitHub repositories, which mean that anyone can not only go ahead and benefit from work already done,
but maybe even decide to improve or extend it. In so doing, maybe some parallelisms and lost working hours can be avoided,
and croud sourcing of useful tools in our research encouraged.
Climate Model: Model of an idealized Moist Atmosphere (MiMA)
As described in Jucker and Gerber, J. Clim. (2017) (see publications),
I have developed an intermediate-complexity General Circulation Model with full moist processes and radiation, but without any cloud effects and very simple surface.
The paper shows much details of the model, but extensive information can be found on GitHub.
Free of charge, just don't forget to cite my work.
Get documentation here: MiMA.
See the file repository here: MiMA GitHub.

Climate Model: Newtonian cooling in dry dynamical cores
As described in
M Jucker, S Fueglistaler, and GK Vallis (2013), J. Atmos. Sci. 70, 3341-3358 (see publications),
I have been working on adding a realistic stratosphere to idealized General Circulation Models.
The above mentioned paper describes how this can be achieved technically and theoretically. In addition, and as support for the paper,
I have created a GitHub repository to make it easy and practical for others to benefit from this work.
At github.com/mjucker/JFV-strat, you can find the raw input files from those studies,
as well as MATLAB scripts and the FORTRAN code needed to reproduce my work easily.
Free of charge, just don't forget to cite my work.
Download the files here: JFV-strat_master.zip.

Visualization with ParaView
As indicated by many of the images on this website, and the
journal articles, workshops, public talks, and awards sections below,
I have developed a skill for scientific visualization. In the spirit of the open source software I have been using for this, mainly
ParaView and Blender, I have created another
GitHub repository which will hopefully grow with the addition of the community.
The package located at github.com/mjucker/pv_atmos includes python scripts
to interact directly with the GUI of ParaView and read in and manipulate netCDF files from geophysical fluid dynamics.
In addition to converting coordinates into log-pressure or an actual sphere, it can also add grid boxes, lines, and labels.
The package is described in detail in
M Jucker, Scientific visualisation of atmospheric data with ParaView, Journal of Open Research Software 2(1):e4.
Feel free to use it, just don't forget to cite my work.

Climate data postprocessing and I/O file operations
Working extensively with climate data and model output, many derived quantities and averages have to be performed routinely.
The aostools suite on GitHub unites most of the functions I use for my work.
This software is still very much a work in progress, and not yet ready to be called a package, as there is still a lot of
documenting to be done. But I have already used it for work I am publishing, which is why I made it completely available as is.
Download the latest version here: aostools_latest.

3D self-consistent integrated modeling of radio-frequency heating in fusion devices
The major product of my PhD thesis is the 3D self-consistent integrated modeling package SCENIC. The package unites three codes to model the interactions between electromagnetic radio-frequency waves, single charged particles, and the global equilibrium of a plasma-filled fusion device. Each of the codes is highly specialized to model its part of the process, and coupling all of them together into one package allows to include the full effects of RF heating in an arbitrary fusion device.
