Software Supplement for article on "Revisiting Diagrams of Ice Growth Environments" by Daniel Hueholt, Sandra Yuter, and Matthew Miller submitted to the *Bulletin of the American Meteorological Society*. Complete set of MATLAB code to plot ice growth diagrams with option to overlay radiosonde data. Code is tested and confirmed operational on MATLAB 2020a+. The three versions of the ice growth diagram are in terms of different moisture variables: relative humidity with respect to water (recommended), relative humidity with respect to ice, and vapor density excess over ice saturation. There are "textbook" and "applied" versions of each ice diagram. The textbook versions are designed to be the most aesthetically-pleasing, while the applied versions are higher-contrast and suitable for data overlays. ![Textbook version of ice growth diagram in terms of relative humidity with respect to water and air temperature.
