Development of the Surface Urban Energy and Water Balance Scheme (SUEWS) for cold climate citiesParameter source

Where: Table 4a, parameters used in SUEWS by surface, p. 1701

Seven surface columns: Bldg, Pav, Everg., Decid., Irr. veg, Grass, Water. Si 0.25, 0.48, 1.3, 0.3-0.8, blank, 1.9, 0; D0,i 10, 10, 0.013, 0.013, 10, 0.013; b 3, 3, 1.71, 1.71, 0.013, 1.71; alpha_i 0.15, 0.09a, 0.10, 0.16b, 0.19, 0.19b, 0.08b; epsilon_i 0.95, 0.91, 0.98, 0.98, 0.93, 0.93, 0.95; gi,max -, -, 7.4, 11.7, 40, 33.1; SWE,i max 190 for each of the six land surfaces and a dash for Water. Footnote a marks a value optimised using data from Helsinki, footnote b marks Vargo et al. (2013).

Development of the Surface Urban Energy and Water Balance Scheme (SUEWS) for cold climate citiesLater compilation

Where: Table 1, characteristics of the observational sites, p. 1696

Five sites: Kumpula, Pasila and Pihlajamäki in Helsinki, and an urban and a suburban site in Montreal. Each Helsinki eddy covariance footprint is a 1 km radius circle and the catchments are 23.8 and 44.8 ha. London is not a study site; the word appears in the article only in a code-availability address and in a publisher's address in the reference list.

Assessment findings

Namesupported
Paved matches Table 4a's Pav column.
Targetsupported
An albedo is a land_cover.paved property.
Valuessupported
Table 4a gives alpha_i 0.09 in the Pav column, which is the stored value.
Sourcesupported
This is one of the few cells the table marks as its own: footnote a reads optimised using data from Helsinki, so Järvi et al. (2014) is the parameter publication here rather than a compiler.
Placesupported
The footnote ties the optimisation to Helsinki data, and Table 1 places three of the study's five sites there.
Representativenesssupported
The optimisation uses Helsinki data from neighbourhood-scale sites. Site is the supported reach and avoids claiming that one fitted value represents the whole city.
Methodsupported
The source explicitly says the value was optimised using Helsinki data. Under the database method definitions, a value fitted to observations or another dataset is fitted even when the paper does not report the objective function or optimisation period.
Identitysupported
A single pavement albedo cell, distinct from the other columns.

Scientific note

The value is in Table 4a, and its footnote marks it as optimised using Helsinki data, making this study the parameter publication rather than a compiler for this cell. The word optimised establishes a fitted method even though the paper does not name the objective function or period. Site reach reflects the neighbourhood-scale evidence without changing the value, place, stable path, target, origin or legacy ID.
