 The latter is the only option for vertically oriented surfaces. 
 Simulations with topography require the application of MOST between each surface and the first computational grid point outside of the topography. 
-For vertical and horizontal downward-facing surfaces, neutral stratification is assumed for MOST. 
+For vertical and horizontal downward-facing surfaces, neutral stratification is assumed for MOST, even if MOST is strictly speaking derived only for upward-facing horizontal surfaces.
+This is simply attributed to the lack of knowledge in the literature about the best practice in this matter. \\
 The topography implementation has been validated by [#letzel2008 Letzel et al. (2008)] and [#kanda2013 Kanda et al. (2013)]. 
 [#park2013 Park and Baik (2013)] have recently extended the vertical wall boundary conditions for non-neutral
