	40	! ------------
[2269]	41	!> Surface module defines derived data structures to treat surface-
[2232]	42	!> bounded grid cells. Three different types of surfaces are defined:
[2269]	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.
[2232]	46	!> In addition, a further derived data structure is defined, in order to set
[2269]	47	!> boundary conditions at surfaces.
