The derivation and delimitation of spaces according to their climatic function required the collation of various basic information. Beside climate parameters data on use and surface structures as well as sealing were evaluated:
- Annual Mean Air Temperature 1991/92 at 2 m Elevation (SenStadtUm 1993c)
- Near Ground Wind Speeds (Map 04.03, SenStadtUm 1994)
- Temperature and Moisture Conditions in Medium and Low-exchange Nocturnal Radiation Periods (Map 04.04, SenStadtUm 1993d)
- Urban Climate Zones (Map 04.05, SenStadtUm 1993e)
- Surface Temperatures at Day and Night (Map 04.06, SenStadtUm 1993f)
- Sealing of Soil Surface (Map 01.02, SenStadtUm 1995a)
- Actual Use of Built-up Areas (Map 06.01, SenStadtUm 1995b)
- Inventory of Green and Open Space (Map 06.02, SenStadtUm 1995c)
- Climate-effective Urban Structure Types (SenStadtUm 1993b)
- Density of Construction (SenStadtUm 1993a)
- Relief Map of the German Planning Atlases (Akademie für Raumordnung und Landesplanung 1949)
For some areas of Berlin expert opinions on climate could be consulted over and above this, so for:
- the Tiergarten (Sukopp et. al. 1979)
- the former “central district” area of West Berlin (borough Tiergarten and Gleisdreieck) (Sukopp et al. 1982)
- the Volkspark Rehberge (Sukopp et al. 1984)
- the Südgelände (Gleisdreieck/ allotment garden Priesterweg) (Horbert et al. 1982) and the Lehrter city station (Horbert 1991).
