    416 The [http://rtweb.aer.com/rrtm_frame.html RRTMG model] is used to calculate the radiative heating rates for each model column. This scheme requires setting [../initialization_parameters#origin_date_time origin_date_time], [wiki:doc/app/initialization_parameters#longitude longitude], [wiki:doc/app/initialization_parameters#latitude latitude], [../initialization_parameters#origin_date_time origin_date_time]. The following parameters can be set optionally: [#albedo_type albedo_type] (and/or [#albedo_lw_dif albedo_lw_dif], [#albedo_lw_dir albedo_lw_dir], [#albedo_sw_dif albedo_sw_dif], [#albedo_sw_dir albedo_sw_dir]). [#constant_albedo constant_albedo] can be used to fix the albedo during the simulation. It is also possible to use the switches [#lw_radiation lw_radiation] and [#sw_radiation sw_radiation].

    418418Please note that the use of RRTMG requires to compile PALM with {{{-D__rrtmg}}} preprocessor directive (in .palm.config.<configuration_identifier> file). But before this, the RRTMG libraries need to be [wiki:doc/tec/radiation#Installation installed].
