31	! Description:
32	! ------------
33	!> Surface module contains defines derived data structures to treat surface-
34	!> bounded grid cells. Three different types of surfaces are defined:
35	!> default surfaces, natural surfaces, and urban surfaces. Moreover, the module
36	!> encompasses the initialization of near-surface grid cells, and handles reading
37	!> and writing restart data.
38	!> In addition, a further derived data structure is defined, in order to set
39	!> boundary conditions at surfaces.
