[1691]	40	! 1682 2015-10-07 23:56:08Z knoop
	41	! Code annotations made doxygen readable
	42	!

[1518]	46	! 1517 2015-01-07 19:12:25Z hoffmann
	47	! advec_s_bc_mod addded, since advec_s_bc is now a module

[1497]	50	! Renamed "radiation" -> "cloud_top_radiation"
	51	!
[1496]	52	! 1484 2014-10-21 10:53:05Z kanani

	58	! 1409 2014-05-23 12:11:32Z suehring
[1409]	59	! Bugfix: i_omp_start changed for advec_u_ws at left inflow and outflow boundary.
	60	! This ensures that left-hand side fluxes are also calculated for nxl in that
	61	! case, even though the solution at nxl is overwritten in boundary_conds()
	62	!
	63	! 1398 2014-05-07 11:15:00Z heinze
[1398]	64	! Rayleigh-damping for horizontal velocity components changed: instead of damping
	65	! against ug and vg, damping against u_init and v_init is used to allow for a

	81	! 1361 2014-04-16 15:17:48Z hoffmann
[1361]	82	! Two-moment microphysics moved to the start of prognostic equations. This makes
	83	! the 3d arrays for tend_q, tend_qr, tend_pt and tend_pt redundant.
	84	! Additionally, it is allowed to call the microphysics just once during the time
	85	! step (not at each sub-time step).
	86	!
	87	! Two-moment cloud physics added for vector and accelerator optimization.
	88	!
	89	! 1353 2014-04-08 15:21:23Z heinze

[1331]	99	! In case of SGS-particle velocity advection of TKE is also allowed with
	100	! dissipative 5th-order scheme.
	101	!
