+! Description:
+! ------------
+!> Calculates change in droplet radius by collision. Droplet collision is
+!> calculated for each grid box seperately. Collision is parameterized by
+!> using collision kernels. Two different kernels are available:
+!> Hall kernel: Kernel from Hall (1980, J. Atmos. Sci., 2486-2507), which
+!> considers collision due to pure gravitational effects.
+!> Wang kernel: Beside gravitational effects (treated with the Hall-kernel) also
+!> the effects of turbulence on the collision are considered using
+!> parameterizations of Ayala et al. (2008, New J. Phys., 10,
+!> 075015) and Wang and Grabowski (2009, Atmos. Sci. Lett., 10,
+!> 1-8). This kernel includes three possible effects of turbulence:
+!> the modification of the relative velocity between the droplets,
+!> the effect of preferential concentration, and the enhancement of
+!> collision efficiencies.

+! Description:
+! ------------
+! This routine is a part of the Lagrangian particle model. Super droplets which
+! fulfill certain criterion's (e.g. a big weighting factor and a large radius)
+! can be split into several super droplets with a reduced number of
+! represented particles of every super droplet. This mechanism ensures an
+! improved representation of the right tail of the drop size distribution with
+! a feasible amount of computational costs. The limits of particle creation
+! should be chosen carefully! The idea of this algorithm is based on
+! Unterstrasser and Soelch, 2014.

+! Description:
+! ------------
+! This routine is a part of the Lagrangian particle model. Two Super droplets
+! which fulfill certain criterion's (e.g. a big weighting factor and a small
+! radius) can be merged into one super droplet with a increased number of
+! represented particles of the super droplet. This mechanism ensures an
+! improved a feasible amount of computational costs. The limits of particle
+! creation should be chosen carefully! The idea of this algorithm is based on

-! Put stochastic equation in an extra subroutine.
-! Set flag for stochastic equation to communicate whether a particle is near
-! topography. This case, memory and drift term are disabled in the Weil equation.

-! Description:
-! ------------
-!> Boundary conditions for the Lagrangian particles.
-!> The routine consists of two different parts. One handles the bottom (flat)
-!> and top boundary. In this part, also particles which exceeded their lifetime
-!> are deleted.
-!> The other part handles the reflection of particles from vertical walls.
-!> This part was developed by Jin Zhang during 2006-2007.
-!>
-!> To do: Code structure for finding the t_index values and for checking the
-!> ----- reflection conditions is basically the same for all four cases, so it
-!> should be possible to further simplify/shorten it.
-!>
-!> THE WALLS PART OF THIS ROUTINE HAS NOT BEEN TESTED FOR OCEAN RUNS SO FAR!!!!

-! Description:
-! ------------
-!> Calculates change in droplet radius by collision. Droplet collision is
-!> calculated for each grid box seperately. Collision is parameterized by
-!> using collision kernels. Two different kernels are available:
-!> Hall kernel: Kernel from Hall (1980, J. Atmos. Sci., 2486-2507), which
-!> considers collision due to pure gravitational effects.
-!> Wang kernel: Beside gravitational effects (treated with the Hall-kernel) also
-!> the effects of turbulence on the collision are considered using
-!> parameterizations of Ayala et al. (2008, New J. Phys., 10,
-!> 075015) and Wang and Grabowski (2009, Atmos. Sci. Lett., 10,
-!> 1-8). This kernel includes three possible effects of turbulence:
-!> the modification of the relative velocity between the droplets,
-!> the effect of preferential concentration, and the enhancement of
-!> collision efficiencies.

-! Description:
-! ------------
-! This routine is a part of the Lagrangian particle model. Two Super droplets
-! which fulfill certain criterion's (e.g. a big weighting factor and a small
-! radius) can be merged into one super droplet with a increased number of
-! represented particles of the super droplet. This mechanism ensures an
-! improved a feasible amount of computational costs. The limits of particle
-! creation should be chosen carefully! The idea of this algorithm is based on
-! Unterstrasser and Soelch, 2014.

-! Description:
-! ------------
-! This routine is a part of the Lagrangian particle model. Super droplets which
-! fulfill certain criterion's (e.g. a big weighting factor and a large radius)
-! can be split into several super droplets with a reduced number of
-! represented particles of every super droplet. This mechanism ensures an
-! improved representation of the right tail of the drop size distribution with
-! a feasible amount of computational costs. The limits of particle creation
-! should be chosen carefully! The idea of this algorithm is based on
-! Unterstrasser and Soelch, 2014.
