4.2.5. SUEWS_NonVeg.txt

SUEWS_NonVeg.txt specifies the characteristics for the non-vegetated surface cover types (Paved, Bldgs, BSoil) by linking codes in column 1 of SUEWS_NonVeg.txt to the codes specified in SUEWS_SiteSelect.txt (Code_Paved, Code_Bldgs, Code_BSoil). Each row should correspond to a particular surface type. For suggestions on how to complete this table, see: Typical Values.

No.	Column Name	Use	Description
1	Code	L	Code linking to a corresponding look-up table.
2	AlbedoMin	MU	Effective surface albedo (middle of the day value) for wintertime (not including snow).
3	AlbedoMax	MU	Effective surface albedo (middle of the day value) for summertime.
4	Emissivity	MU	Effective surface emissivity.
5	StorageMin	MD	Minimum water storage capacity for upper surfaces (i.e. canopy).
6	StorageMax	MD	Maximum water storage capacity for upper surfaces (i.e. canopy)
7	WetThreshold	MD	Depth of water which determines whether evaporation occurs from a partially wet or completely wet surface [mm].
8	StateLimit	MD	Upper limit to the surface state. [mm]
