1950 | kind of topography to be used is controlled by the new initialization |

1952 | Allowed values are <span style="font-style: italic;">'flat'</span>, |

1957 | For the single building case, the building (rectangular) size |

---|
1972 | In case of NetCDF-output, the time-averaged data is output to |

1973 | additional files (seperate from the non-averaged output). The length of |

1974 | the averaging interval and the temporal distance of the single |

1991 | of the cloud droplet code is mainly done by re-sorting all particles |

2436 | release contains further additions, changes, and bugfixes for the |
---|
2437 | SGI-ICE system, as well as important changes like the splitting of the |
---|
2438 | user-interface into single files, a complete revision of the |
---|
2439 | pre-compiling mechanism allowing to use different make-depositories |
---|
2440 | simultaneously, and a revision of the reading-mechanism from restart |
---|
2441 | files, which has no more restrictions in case that the previous and |
---|
2442 | current run have different domain/subdomain sizes. A new handling of |
---|
2443 | all kind of output messages is introduced with this release and will be |

2482 | atmosphere-ocean coupling has been improved and steering of |

2486 | <br> |

2487 | The atmosphere-ocean coupling allows to use independent precursor runs |
