The Surface Urban Energy and Water Balance Scheme (SUEWS): Evaluation in Los Angeles and Vancouver.Parameter source

Where: Table 2, model parameter values by surface type and general run options, p. 223

Publishes LAImax,con 5.1 and LAImin,con 4; footnote c traces the maximum to Breuer et al. (2003), while the table directly publishes the complete pair used by SUEWS.

Plant parameter values for models in Temperate climatesInput observations

Where: Table 7, parameter values for land covers in global temperate ecosystems, p. 286

Publishes median LAI 5.1 for coniferous forest; it does not publish the lower bound 4.

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

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

Repeats LAImax,everg 5.1 and LAImin,everg 4.0 and states that values use Järvi et al. (2011) sources unless otherwise indicated.

Surface Urban Energy and Water Balance Scheme (SUEWS): Development and evaluation at two UK sitesValidation

Where: Sect. 4.1, seasonal cycle of vegetation phenology, p. 7

Evaluates the timing of the modelled seasonal LAI cycle from site photographs and adjusts degree-day temperatures, but does not publish 4/5.1 as newly fitted SE England bounds.

Assessment findings

Namecuration required
Evergreen Tree follows Järvi's coniferous-tree SUEWS category, but the SE England qualifier is later application context rather than the scope of the published bounds.
Targetsupported
Järvi et al. publish the two bounds for the coniferous-tree SUEWS vegetation category represented by land_cover.evetr.
Valuessupported
Järvi et al. (2011) Table 2 publishes LAImin 4 and LAImax 5.1 for coniferous trees. Järvi et al. (2014) Table 4 repeats the pair. Breuer Table 7 supplies the 5.1 coniferous-forest median but not the lower bound 4.
Sourcesupported
Järvi et al. (2011) are the earliest located direct publisher of the complete 4/5.1 record. Järvi et al. (2014) explicitly reuse the earlier source set, while Ward et al. evaluate seasonal timing without publishing these bounds as a new SE England fit.
issue #147
Placecuration required
Järvi Table 2 publishes general SUEWS model parameters, not an SE England determination. Ward establishes the UK application context but does not establish the bounds as regional evidence.
Representativenesscuration required
The values are literature/default bounds reused in later applications. Calling the stable migration record regional SE England evidence is not established by the sources.
Methodsupported
The record transcribes a published SUEWS parameter pair.
Identitycuration required
The Shanghai XJH record and generic Beijing-path record now carry the same thermal-only selector and 4/5.1 bounds under different application identities, while this SE England record retains the day-length selector 1 with the same bounds. Whether the stable SE England path is a quoted default or distinct regional evidence requires curation; this source correction neither merges nor deletes any record.

Scientific note

The complete LAI pair is sourced to Järvi et al. (2011), not to Breuer alone: Breuer supports the maximum 5.1 but not the minimum 4. Järvi et al. (2014) repeat both values, and Ward et al. evaluate phenological timing without republishing the bounds. The stable path, name, place and regional class are retained as migration/application identity and remain curation-required because overlapping migrated records exist.
