| 6 | PALM is an advanced and modern meteorological model system for atmospheric and oceanic boundary-layer flows. It has been developed as a turbulence-resolving large-eddy simulation (LES) model that is especially designed for performing on massively parallel computer architectures. Since PALM 5.0, the model is shipped along with several PALM-4U (PALM for urban applications, read: ''PALM for you'') components that allow to employ the model for various urban applications ranging from the meso- to the microscale. |

| 16 | The model PALM consists of a dynamic solver for the Navier-Stokes equations and the first law of thermodynamics. By default, the model is used in an LES mode in which the bulk of the turbulent motions in the atmospheric boundary are explicitly resolved. |

| 50 | * A Reynolds-averaged Navier Stokes (RANS) type turbulence parameterization can be used instead of LES to reduce computational costs |
