| 557 | | == [=#output Output steering in `runtime_parameters`] == |
| 558 | | |
| 559 | | Output of chemistry variables follows the usual output steering as described in [https://palm.muk.uni-hannover.de/trac/wiki/doc/app/d3par#output `Data Output`]. |
| 560 | | |
| 561 | | Names of chemistry variables must be preceded by {{{kc_'}}}. |
| 562 | | |
| 563 | | Example: |
| 564 | | {{{ |
| 565 | | data_output = 'w', 'w_av', |
| 566 | | 'q', 'q_av', |
| 567 | | 'kc_PM10', 'kc_NO2', 'kc_NO', 'kc_O3', 'kc_PM10_av', 'kc_NO2_av', |
| 568 | | }}} |
| 569 | | |
| 570 | | Possible output includes 2d cross section and/or 3d volume data (instantaneous and averaged) as well as instantaneous and averaged profiles. |
| 571 | | |
| 572 | | |
| 573 | | ''Note that time series output is not available yet!'' |

| 578 | | == [=#init Initialisation steering in `initialization_parameters`] == |
| 579 | | |
| 580 | | If large-scale forcings from INIFOR are used only for meteorology, then user defined initial concentration and initial vertical [#cs_profiles profiles] can be activated by combining {{{set_constant_profiles}}} with {{{inifor}}} separated by a space only in the [wiki:inipar#initializing_actions initializing_parameters] namelist. |
| 581 | | |
| 582 | | Example:\\ |
| 583 | | {{{initializing_actions = 'inifor set_constant_profiles', }}} |
| 584 | | |
| 585 | | \\ |
| 586 | | |
| 587 | | == [=#testsetups Example setups] == |
| 588 | | |
| 589 | | The PALM-4U subdirectory TESTS/cases contains some sample setups for different application types. An setup for a very small urban area with the 'phstatp' mechanism can be found in 'urban_environment' and 'urban_environment_restart'. |
| 590 | | |
| 591 | | An example setup with two passive tracers for the small test_urban model domain is attached to this page (Attachment test_urban_chem_passive.tar). |
| 592 | | |
| 593 | | Further setups are attached for a 1km x 1km model domain with 10 m grid width, which is centered around the Ernst-Reuter-Platz in Berlin . For this domain, example input files are supplied for two chemistry settings: |
| 594 | | two passive compounds ('passive')\\ |
| 595 | | the 'smog' mechanism\\ |
| 596 | | |
| 597 | | Please note that PALM-4U comes by default with the code for the photostationay equilibrium between NO, NO2 and O3 plus one passive tracer, i.e. {{{chem_gashase_mod.f90}}} is prepared for 'phstatp'. In order to run PALM-4U e.g. with the 'smog' mechanism, copy the {{{chem_gashase_mod.f90}}}, which is supplied in {{{UTIL/chemistry/gasphase_preproc/mechanisms/def_smog}}} into {{{SOURCE}}} (or execute {{{run_kpp4palm.ksh -m smog}}}). |
| 598 | | |
| 599 | | So far, all example setups are supplied for 'PARAMETERIZED' emissions. Example emissions files for 'PREPROCESSED' and 'DEFAULT' emissions will be supplied here at a later time. |
