Changelog not available	Changelog not available	Changelog not available	5.0	C,N	SVN commit message: Changelog not available (Makefile, chemistry_model_mod, init_3d_model, land_surface_model_mod, modules, palm, parin, radiation_model_mod, read_3d_binary, read_restart_data_mod, read_var_list, sum_up_3d_data, surface_mod, synthetic_turbulence_generator_mod, urban_surface_mod, user_last_actions, user_module, user_read_restart_data, user_read_restart_data_mod, uv_exposure_model_mod, virtual_flight_mod, wind_turbine_model_mod, wrd_write_string, write_3d_binary, write_restart_data_mod, write_var_list) Changed: Structure of reading/writing restart data was changed to make it more clearly. Subroutine names with respect to reading/writing restart data has been renamed. Redundant skipping functions that skip module related global parameters have been removed. Arising mistakes that could occur during reading/writing new restart data have been prevented (e.g. the order of subroutine calls in case of reading/writing module related restart data does not matter). New: Strings and their respective lengths are written out (wrd_write_string) and read now in case of restart runs to get rid of prescribed character lengths. New module read_restart_data_mod contains modified content of read_3d_binary and read_var_list which have been deleted. New module write_restart_data_mod contains modified content of write_3d_binary and write_var_list which have been deleted. Introduction of modules that read/write user specific restart data (user_read_restart_data_mod, user_write_restart_data_mod) and deletion of the old user_read_restart_data file.

(init_3d_model) (Usually, array 'rmask' used to set-up statistic regions is initialized in routine 'user_init'.
