SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: Pre-migration OHM row 50240017

The pinned migration transcript stores Buildings, Canyon (E-W), Japan, Tokyo origin, the exact coefficient tuple, and Ref null as a distinct row.

This artifact establishes the retained configuration identity only; it is not a publication of an independent Tokyo OHM fit.

Field measurements on energy balance of an urban canyon in the summer seasonValidation

Where: Sections 2-5 and Figures 3-12, p. 418-423

Reports the Kyoto east-west canyon observations underlying the related code-[10] row, but does not identify Ref-null database row 50240017.

Heat storage in Urban Areas: Local-Scale Observations and Evaluation of a Simple ModelValidation

Where: Table 4, E-W canyon, p. 932

Publishes 0.71, 0.04 h and -39.7 W m-2 for the E-W canyon, matching this row numerically, but does not identify Ref-null database row 50240017.

Canyon (E-W), Japan [10]Related record

Pre-migration row 50240012 carries the same tuple but includes code [10] and Ref 99240099, while this row 50240017 omits the code and stores Ref null; see https://github.com/UMEP-dev/SUEWS-database/blob/053c004ef46c14194fdc39bbb8932908db294abd/db/ohm.yml#L117-L170.

Assessment findings

Namesupported
Archived Tokyo E-W canyon configuration identifies the retained catalogue row without presenting it as a second published or independently fitted OHM determination.
Targetsupported
The archived row explicitly stores the three OHM coefficients under the Buildings surface. Any future archetype attachment remains a separate composition question.
Valuessupported
Pre-migration row 50240017 directly stores 0.71, 0.04 and -39.7. This supports configuration lineage only; the matching published tuple belongs to the separately identified code-[10] row.
Sourcesupported
Source unreferenced is required. The archived row has Ref null, and numeric equality does not authorize transferring the Grimmond and Oke citation from the distinct code-[10] row. The pinned repository artifact is compilation evidence for configuration identity, not a scientific source.
Placesupported
Tokyo is retained solely as the row's explicit historical application label. It is not asserted as an observation or fitting site; the related code-[10] observations are independently located in Kyoto.
Representativenesssupported
City describes the retained Tokyo-labelled application configuration only. It does not claim city-wide empirical support or extend the Kyoto evidence to Tokyo.
Applicable Scalesupported
The retained row is a canyon/building-surface coefficient configuration, and the related published tuple is fitted to an east-west canyon surface before any area-weighted neighborhood aggregation.
issue #46
Methodsupported
Assumed is the honest classification because the Ref-null row preserves a configuration choice without a documented calculation or independent fit. The fitted method of the related code-[10] row is not transferred.
Identitysupported
Stable path, legacy ID 50240017, Tokyo origin, missing code marker and Ref-null state preserve this as a distinct archived migration row. Retention does not claim a second scientific determination and does not transfer the verified Kyoto citation from the related code-[10] row.
issue #738

Scientific note

This Ref-null row is retained as a distinct archived Tokyo-labelled configuration, not treated as a second scientific determination and not credited with the verified Kyoto source chain of the related code-[10] row. Its stable path, origin, values and legacy ID remain unchanged. The repository transcript establishes migration identity only; source remains unreferenced and method is assumed. Any future building-archetype attachment requires a separate composition review.
