40	! ------------
41	!> Surface module defines derived data structures to treat surface-
42	!> bounded grid cells. Three different types of surfaces are defined:
43	!> default surfaces, natural surfaces, and urban surfaces. The module
44	!> encompasses the allocation and initialization of surface arrays, and handles
45	!> reading and writing restart data.
46	!> In addition, a further derived data structure is defined, in order to set
47	!> boundary conditions at surfaces.
