| 3 | PALM provides two nesting systems. |
| 4 | A multi-scale self nesting is available where PALM model domains can be recursively nested within each other and the corresponding model simulations run in parallel to each other with an continuous communication at runtime. |
| 5 | Further, PALM provides the possibility to nest the model domain within larger-scale models, where the larger-scale model runs in advance, providing time-dependent boundary condition for the subsequent PALM run. |
| 6 | The nesting within larger-scale models is hence referred to as offline nesting. |
| 7 | Both nesting systems can be used at the same time, which allows to resolve small-scale phenomena without neglecting larger-scale processes on the synoptic scale. |
