GRAL includes three programs:|the lagrangian dispersion model GRAL, the mesoscale wind field model GRAMM and the graphical user interface GUI.|The programs are running on Windows and LINUX (the calculation kernels on .Net Core, the GUI on Windows Forms or MONO WinForms).The MONO- WinForms support of the GUI for LINUX is unfortunately not as stable as the Windows version.
You can visualize wind data in numerous ways. For classified wind data, a bias correction (automatic detection of classified data and upsampling) was provided to avoid errors when splitting the classified wind data into the wind sectors of the wind roses. Wind roses can be plotted with sector widths of 22.5°, 15° or 10°.
