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 Grass is the database target used by irrigated and unirrigated grass archetypes. Table 4(a) gives the same 190 mm threshold in its Irr. veg and Grass columns; this shared record captures that common value without implying that the two source classes are otherwise interchangeable. |
|---|---|
| Target | supported Table 4(a) publishes SWE_i,max for Irr. veg and Grass, both represented by land_cover.grass in the current database schema. |
| Values | supported Table 4(a) gives SWE_i,max as 190 mm in both the Irr. veg and Grass columns, 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 unqualified Irr. veg and Grass model defaults 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 current schema maps both vegetation columns to one grass target, while retaining target-specific records for the other supported land covers. The bare-soil sibling remains unsupported because the table has no bare-soil column. |
Järvi et al. (2014) Table 4(a) directly publishes both irrigated-vegetation and grass SWE_i,max as 190 mm. The database has one land_cover.grass target, so one record serves irrigated and unirrigated grass archetypes for this shared threshold only. 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.
