The article publishes the paved composite; the companion table states that code 851 is the average of codes 801, 802, 901, 902 and 910 and supplies the exact tuple.

The same surface coefficient scheme is applied at both sites; this is application and validation evidence.
| Name | supported Paved surface composite identifies Ward's exact code 851 average of paved-material inputs without extending it to buildings or all non-vegetated surfaces. |
|---|---|
| Target | supported Ward et al. define the triplet as coefficients in the OHM storage-heat equation. |
| Values | supported Table 4 prints the rounded paved tuple 0.676, 0.300, -42.4; the companion code 851 row gives the exact stored tuple 0.676, 0.300, -42.42. |
| Source | supported Ward et al. publish this paved composite and the versioned companion table gives its exact values. |
| Place | supported Generic is appropriate because the coefficient set is compiled from surface-material studies and applied at both London and Swindon; it is not a London observation or fit. |
| Representativeness | supported Ward presents code 851 as a generic paved-surface literature composite used at two distinct sites, so generic representativeness matches the evidence. |
| Applicable Scale | supported Equation 6 weights the coefficients for each surface type by its surface cover fraction, and Table 4 lists this tuple for Paved, so it is a land-cover input before neighborhood aggregation. |
| Method | supported The database adopts Ward's published output. Ward's authors calculate code 851 as the arithmetic mean of concrete/asphalt codes 801, 802, 901, 902 and 910; it is not a London fit. |
| Identity | supported The active name and scope identify one generic paved composite. The stable path and origin retain the migration lineage without controlling the evidence identity. |
Ward et al. publish code 851 as a paved-surface composite compiled from concrete and asphalt studies and use it as a land-cover input before surface-fraction aggregation in the London and Swindon evaluations. The active name, place and representativeness describe that generic literature evidence. The stable path and origin retain the legacy London/all-nonvegetated migration lineage, and the values remain unchanged.
