alb | 0.21 |
Where: Table 2, BSoil row and footnote a, p. 8
Publishes original bare-soil albedo 0.21 and adjusted albedo 0.18; the footnote explains that earlier model versions assigned bare soil the non-irrigated-grass albedo.
Where: Table 1, Kc surface-cover fractions, p. 5
Gives the central-London Kc bare-soil fraction as zero, so the original 0.21 value is inert there and cannot be read as a London-derived parameter.
Where: SUEWS_NonVeg.txt, code 663 London BSoil row
Stores albedo 0.18 for the London bare-soil application, separating the adjusted release row from this migrated 0.21 original-value record.
| Name | supported BareSoil is the compressed legacy surface token for the BSoil/Bare soil class used in Ward Table 2 and the historical release registry. |
|---|---|
| Target | supported Ward Table 2 publishes the value by surface type and identifies BSoil as the non-vegetated bare-soil land-cover class. |
| Values | supported Table 2 publishes 0.21 as the original bare-soil albedo and 0.18 as the adjusted UK value. The record is the legacy original-value row, so 0.21 is retained. The pinned London application uses 0.18, confirming that this 0.21 row is not the active London-adjusted input. issue #110 |
| Source | supported Ward et al. directly state both the original and adjusted values and explain their use. The release registry is later application evidence for the adjusted London row. |
| Place | supported Generic is the supported active place because 0.21 is the pre-adjustment model default. London had zero bare-soil cover and its pinned release row uses the adjusted 0.18 value; London remains only as stable-path and origin lineage. issue #110 |
| Representativeness | supported Generic reach describes an original literature/model default that was not fitted to London. City reach would misstate an inert value from a site with zero bare-soil cover. issue #110 |
| Applicable Scale | supported Table 2 organises albedo by SUEWS surface type, so 0.21 describes the bare-soil land-cover class rather than a neighbourhood bulk albedo or material specimen. |
| Method | supported Literature describes retaining the original published model-input value; this record performs no new measurement, fit or calculation. |
| Identity | supported The stable path, London origin, source, target, legacy ID and 0.21 value preserve the migrated original-value row. The different 0.18 release application is documented rather than collapsed into this identity. |
Ward et al. distinguish original bare-soil albedo 0.21 from the adjusted UK value 0.18. The central-London site has zero bare-soil fraction, and the pinned v2016a London row stores 0.18. The retained 0.21 record is therefore a generic literature/model default, not London city evidence. Its stable London path and origin preserve migration lineage; no parameter value, source, target or legacy ID changed.
