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).

States that snow accumulation and melt were not yet included in SUEWS, ruling this paper out as the source of a snowpack threshold.
| Name | supported Buildings matches the Bldg surface column from which the value is read. |
|---|---|
| Target | supported Table 4(a) publishes SWE_i,max as a building-surface model parameter, matching land_cover.bldgs. |
| Values | supported Table 4(a) gives SWE_i,max as 190 mm in the Bldg column, exactly matching the stored value. |
| Source | supported Järvi et al. (2014) are the first accessible publication of the 190 mm SUEWS threshold. The blanket Table 4 caption cannot make Järvi et al. (2011) its source because that paper explicitly states that snow accumulation and melt were not yet modelled. |
| Place | supported Table 4(a) presents one unqualified building-surface model default used across the Helsinki and Montreal applications. Generic records the absence of a source-specific place claim; it does not assert universal empirical validity. |
| Representativeness | supported The publication gives the threshold as an unqualified model default rather than a fitted Helsinki or Montreal result, so generic is the supported evidence class. |
| Applicable Scale | supported SWE_i,max is tabulated separately by SUEWS land-cover surface; the value therefore applies at land-cover scale. |
| Method | supported Literature records direct adoption of the published Table 4(a) model input without a new calculation or fit in this database. |
| Identity | supported Table 4(a) assigns 190 mm to buildings, pavement, evergreen trees, deciduous trees, irrigated vegetation and grass. The retained target-specific records therefore represent deliberate per-land-cover applications rather than accidental duplicates; the bare-soil sibling remains unsupported because the table has no bare-soil column. |
Järvi et al. (2014) Table 4(a) directly publishes building-surface SWE_i,max as 190 mm. It is distinct from the 40/100 mm SWE_Lim snow-transport thresholds discussed elsewhere in the paper. The record now treats 190 mm as an unqualified land-cover default rather than a Helsinki city determination. No value, stable path, name, target, origin or legacy ID changes.
