 The nesting within larger-scale models is hence referred to as offline nesting. 
 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.  
-The following sections contain a documentation of the PALM self nesting as well as of the offline nesting in larger-scales models, which include a general description of the method, the required input parameters, preparatory steps, as well as example setups.

 A multi-scale self nesting system is available since -r1763. 
 In the self nesting, there is one root model with up to 63 child model domains which are embedded into the root model. Child domains, in turn, can be recursively nested into each other, where a model domain can be parent and child domain at the same time. 
-The child domain obtains boundary data of the three velocity components and all prognostic scalar variables from the parent domain, where the boundary data is interpolated from the coarse parent grid onto the fine child grid.  
+The child domain obtains boundary data of the three velocity components and all prognostic scalar variables from the parent domain, where the boundary data is interpolated from the coarse parent grid onto the fine child grid. 
+The other way around, the updated child solution after the timestep is transferred back onto the parent grid by anterpolation. 
+The self-nesting can be operated as a 1-way nesting, where only the anterpolation step is omitted, i.e. there is no feedback in the parent by the child model, and as a 2-way nesting, where parent and child solution mutually depend on each other. 
+
+Child models can be recursively nested within each other under the condition that the child model fits completely into its respective parent domain without any overlap. 
 
 '''Please note:''' The PALM self nesting currently undergoes major testing and revisions. A more detailed description will follow after the official release.
