Urban Storage Heat Flux Variability Explored Using Satellite, Meteorological and Geodata.Later compilation

Where: Pre-migration Spartacus Material row 36243787

Names the row Outer wall [sample run], stores 0.5, 0.95, 0.760645 and 1050, leaves density null, and carries Ref 90240057. This proves configuration lineage, not a publication claim.

Urban Storage Heat Flux Variability Explored Using Satellite, Meteorological and Geodata.Later compilation

Where: Historical SUEWS_ESTMCoefficients.txt, code 801 wall layer one

Stores thickness 0.087 m, conductivity 0.760645 W m-1 K-1 and volumetric heat capacity 1046908.363 J m-3 K-1 for wall layer one of GLA Urban fabric >80. It does not publish an atomic material with the migrated optical values or a specific-heat/density split.

Urban Storage Heat Flux Variability Explored Using Satellite, Meteorological and Geodata.Validation

Where: Table 2, ESTM surface material properties, p. 274, 275

Publishes six distinct London wall-class conductivity/volumetric-heat-capacity pairs and their component material classes, not the historical code-801 layer-one tuple as one atomic material.

Central London [sample run]Related record

Selects this record as wall layer one of the retained Central London sample configuration.

Assessment findings

Namesupported
Archived code-801 wall-layer fixture identifies the retained release-layer configuration without presenting it as one physical material or a verbatim Lindberg Table 2 value.
issue #252
Targetsupported
The migrated row represents one material-layer reference selected by a construction record, matching the material target even though its values are retained as configuration fields rather than a source-published material specimen.
Valuessupported
The exact four-value tuple is supported only as preserved migration/configuration lineage. Historical code 801 confirms wall-layer-one conductivity 0.760645 and volumetric heat capacity 1.046908363 MJ m-3 K-1. The migrated material row stores 1050 under specific_heat without density, so it cannot honestly represent that volumetric quantity as a physical material property; the optical values are not published by Lindberg Table 2.
Sourcesupported
Unreferenced is correct because no publication states or derives this exact atomic four-value material tuple. source_legacy_ref 90240057 preserves the Lindberg registry link recorded during migration without exporting the article as the tuple's parameter source.
issue #252
Placenot applicable
The generic fixture row makes no observation-place claim.
Representativenessnot applicable
The fixture makes no site, city or regional evidence-reach claim.
Methodsupported
Assumed marks the exact retained layer mapping as a configuration choice, not a measured, fitted, calculated or verbatim literature material.
issue #252
Identitysupported
Legacy ID 36243787 preserves a distinct material-registry row selected as wall layer one in the retained Central London code-801 configuration. Its stable identity remains while the display and provenance make its non-physical catalogue role explicit.

Scientific note

This record remains solely as an archived code-801 wall-layer fixture. Its stable path and exact legacy values preserve the Central London construction record, but it is not presented as a physical material published by Lindberg et al. Historical code 801 supplies k 0.760645 and rhoCp 1046908.363 for one wall layer, while the migrated row stores 1050 under specific_heat with no density and adds optical values absent from Table 2. Source unreferenced, method assumed and the archived display name make the boundary explicit without guessing a density, changing values or rewriting downstream construction identity.
