v11 v12 6 6 7 7 === Features under development: === 8 * '''Aerosol chemistry''' (expected February 2018) 9 * '''Biometeorological analysis products''' (expected January 2018) 10 * '''Indoor climate and energy demand model''' (expected February 2018) 8 11 * '''Multi-agent system''' for humans in urban environments (expected May 2018) 9 * '''Indoor climate and energy demand model''' (expected February 2018)10 12 * '''RANS mode:''' TKE-epsilon turbulence closure for urban simulations (expected January 2018) 11 * '''Biometeorological analysis products''' (expected January 2018)12 * '''Aerosol chemistry''' (expected February 2018)13 13 14 14 ---- … … 17 17 18 18 === 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 19 32 * '''Land surface scheme''' (PALM): 20 33 * Support for water and paved surfaces added ([wiki:doc/tec/lsm details]). 21 34 * 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 23 42 * '''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 32 44 * '''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 37 46 * '''Synthetic turbulence generator''' (PALM): A turbulence gerator can be used instead of turbulence recycling for non-cyclic inflow conditions 38 47 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 39 54 === Major changes: === 55 * '''Multigrid solver''' (PALM): Optimized multi-grid pressure solver is implemented. 40 56 * '''Surface treatment''': 41 57 * '''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]).
