    1818=== New features: ===
     19
     20* '''Chemistry model''' (PALM-4U): A gas-phase chemistry has been implemented.
     21
     22* '''Cloud microphysics''' (PALM): Advanced bulk microphysics implemented. This basically involves two additional prognostic equations for the cloud droplet number concentration, and the cloud water content as well as aerosol activation schemes.
     23
     24* '''GUI tools''' (PALM): Graphical helper tools have been added (PALM grid finder, palm_gf; PALM watchdog, palm_wd, PALM job manager, palm_jm).
     25
     26* '''INIFOR''' (PALM-4U): Forcing by COSMO-DE large-scale data is realized via NetCDF interface and preprocessing tool INIFOR.
     27
     28* '''Interface for reading NetCDF input data:''' (PALM-4U): Input data (e.g. building heights, land surface classification, etc.) are not read from NetCDF driver files.
     29
     30* '''Lagrangian cloud model:''' (PALM): Splitting/merging algorithm implemented.
     31
    1932* '''Land surface scheme''' (PALM):
    2033  * Support for water and paved surfaces added ([wiki:doc/tec/lsm details]).
    2134  * Revised skin layer concept and soil model configuration ([wiki:doc/tec/lsm details]).
    22 * '''Urban surface scheme''' (PALM-4U): An energy balance solver for buildings and a wall material model.
     35
     36* '''LES-LES self-nesting''' (PALM-4U): Multi-stage LES-LES nesting is realized for most quantities (except chemistry) ([wiki:doc/tec/nesting details]). Also, two different 1D vertical nesting schemes are available.
     37
     38* '''Model steering''' (PALM): The old scripts mrun and mbuild have been removed in favor of more user-friendly scripts palmrun and palmbuild.
     39
     40* '''Radiation model''' (PALM): Coupling to RRTMG radiation code realized. RRTMG is now shipped with PALM.
     41
    2342* '''Radiative transfer''' (PALM-4U): Radiative transfer in the urban canopy layer, including multiple reflections between buildings and shading of tall vegetation. Can also be used in complex terrain.
    24 * '''LES-LES self-nesting''' (PALM-4U): Multi-stage LES-LES nesting is realized for most quantities (except chemistry) ([wiki:doc/tec/nesting details]). Also, two different 1D vertical nesting schemes are available.
    25 * '''Cloud microphysics''' (PALM): Advanced bulk microphysics implemented. This basically involves two additional prognostic equations for the cloud droplet number concentration, and the cloud water content as well as aerosol activation schemes.
    26 * '''Interface for reading NetCDF input data:''' (PALM-4U): Input data (e.g. building heights, land surface classification, etc.) are not read from NetCDF driver files.
    27 * '''Chemistry model''' (PALM-4U): A gas-phase chemistry has been implemented.
    28 * '''INIFOR''' (PALM-4U): Forcing by COSMO-DE large-scale data is realized via NetCDF interface and preprocessing tool INIFOR.
    29 * '''Model steering''' (PALM): The old scripts mrun and mbuild have been removed in favor of more user-friendly scripts palmrun and palmbuild.
    30 * '''Wind turbine model''' (PALM): A wind turbine model was implemented ([wiki:doc/tec/wtm details]).
    31 * '''Testsuite''' (PALM): New svn commits are now automatically tested.
     43
    3244* '''Spin-up''' (PALM-4U): A spin-up mechanism is available for running land surface model, urban surface model and radiation scheme independently from atmosphere to generate steady-state soil and wall temperatures for initialization.
    33 * '''Lagrangian cloud model:''' (PALM): Splitting/merging algorithm implemented.
    34 * '''GUI tools''' (PALM): Graphical helper tools have been added (PALM grid finder, palm_gf; PALM watchdog, palm_wd, PALM job manager, palm_jm).
    35 * '''Multigrid solver''' (PALM): Optimized multi-grid pressure solver is implemented.
    36 * '''Radiation model''' (PALM): Coupling to RRTMG radiation code realized. RRTMG is now shipped with PALM.
     45
    3746* '''Synthetic turbulence generator''' (PALM): A turbulence gerator can be used instead of turbulence recycling for non-cyclic inflow conditions
    3847
     48* '''Testsuite''' (PALM): New svn commits are now automatically tested.
     49
     50* '''Urban surface scheme''' (PALM-4U): An energy balance solver for buildings and a wall material model.
     51
     52* '''Wind turbine model''' (PALM): A wind turbine model was implemented ([wiki:doc/tec/wtm details]).
     53
    3954=== Major changes: ===
     55* '''Multigrid solver''' (PALM): Optimized multi-grid pressure solver is implemented.
    4056* '''Surface treatment''':
    4157* '''Topography implementation''': Topography is now considered via flag arrays instead of 2D index arrays. Overhanging structures like bridges are now possible, i.e., the limitation of surface-mounted topography does not exist anymore. A topography filter was implemented that fills holes that consist of only one grid point [wiki:doc/tec/topography#topo details]).
