 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 [../inipar#day_of_year_init day_of_year_init], [wiki:doc/app/inipar#longitude longitude], [wiki:doc/app/inipar#latitude latitude], [../inipar#time_utc_init time_utc_init]. 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].
 
-Please note that the use of RRTMG requires to compile PALM with {{{__rrtmg}}} preprocessor directive. By the same token it is not possible to switch the radiation scheme to 'clear-sky' or 'constant' for such a compiled PALM executable.
+Please 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]. The code compiled with {{{-D__rrtmg}}} '''cannot''' be used with '''radiation_scheme''' = 'clear-sky' or 'constant'.
