SUEWS v2016a release workbook: SUEWS_SiteInfo18_Lo.xlsmLater compilation

Where: Pre-migration Albedo row 41240048

Stores Snow, the name Snow (not used in Ward et al. 2016), origin SE England, minimum 0.18, maximum 0.80 and Ref 90240002.

SUEWS v2016a release workbook: SUEWS_SiteInfo18_Lo.xlsmLater compilation

Where: V2016a SUEWS_Snow.txt historical input rows

Rows 550, 660 and 999 all preserve AlbedoMin 0.18 and AlbedoMax 0.80. The file labels 550 Swindon and 660 London, while providing no derivation for the pair.

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

Where: Model setup and evaluation, p. 6, 8

The study does not use snow physics and does not publish a 0.18 and 0.80 snow-albedo pair.

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

Where: Table 4b, overall-area snow parameters, p. 1701

Publishes minimum snow albedo 0.18 and maximum snow albedo 0.85, not the stored 0.80 maximum.

Assessment findings

Namesupported
Archived SE England snow-albedo configuration identifies the preserved migration row without implying that Ward et al. (2016) used or determined the values.
issue #107
Targetsupported
The two stored fields are the minimum and fresh-snow albedo limits used by the SUEWS snow target.
Valuessupported
The exact 0.18 and 0.80 pair is supported as a preserved historical configuration. The 2016a input contains the same pair in its Swindon, London and default rows. Järvi et al. (2014) instead publish 0.18 and 0.85, so that publication is not transferred to this pair.
Sourcesupported
Unreferenced is correct because Ward et al. (2016) did not use snow physics and do not publish this pair, while Järvi et al. (2014) publish a different maximum. source_legacy_ref 90240002 preserves the former database link without exporting Ward as the parameter publication.
issue #107
Placesupported
SE England is retained as the archived row's application identity. It is not presented as the site where the albedo limits were empirically determined.
Representativenesssupported
Regional describes the intended scope of the archived SE England configuration, not the reach of an empirical snow-albedo study.
Methodsupported
Assumed records retention of an exact historical configuration whose scientific derivation is not supplied by the migration row or release artifact.
issue #107
Identitysupported
Legacy ID 41240048 and the pre-migration name explicitly saying the values were not used in Ward et al. (2016) establish a distinct archived configuration identity. The stable path and origin remain unchanged for traceability.

Scientific note

This record remains solely as an archived SE England application configuration. The exact 0.18/0.80 pair is preserved in both the pre-migration catalogue and historical v2016a inputs, but neither artifact gives its scientific derivation. Ward et al. (2016) did not use snow physics, and Järvi et al. (2014) publish a different 0.18/0.85 pair. Source unreferenced prevents false attribution; method assumed and the archived name state the record's actual role; source_legacy_ref 90240002 preserves the historical catalogue link. No value, stable path, origin or legacy ID changes.
