emis | 0.94 |
Where: Table 2, Bare soil, emissivity row, p. 8
Publishes BSoil emissivity 0.94 for the London and Swindon configurations. The accompanying note says BSoil was not fully implemented in earlier SUEWS versions and its emissivity was based on the range in Oke (1987).
Where: Table 1.1, Radiative properties of natural materials, p. 12
Gives soils an emissivity range from 0.90 for light, dry soil to 0.98 for dark, wet soil and collectively cites Sellers (1965), List (1966), Paterson (1969), and Monteith (1973); it does not identify a source per cell or the exact 0.94 selection.
| Name | supported Ward et al. label the newly implemented surface class BSoil, matching the retained bare-soil label. |
|---|---|
| Target | supported Table 2 assigns the emissivity to BSoil, matching land_cover.bsoil. |
| Values | supported Ward et al. publish the exact BSoil emissivity 0.94. Oke gives soils a 0.90 to 0.98 range, supporting the range from which Ward selected the value but not by itself identifying 0.94. |
| Source | supported Ward et al. are the checked source that introduces the BSoil class and publishes its exact 0.94 value. Oke is the stated upstream range evidence, not the exact parameter source. issue #1083 |
| Place | supported Ward et al. use the BSoil parameter in their London and Swindon configurations. The shared se-england place records that documented application geography without claiming a regional determination. |
| Representativeness | supported Ward et al. document the value for two specific study-site configurations, not as a regional determination. Site is therefore the supported evidence reach. |
| Method | supported Ward et al. select the value from Oke's published soil-emissivity range, so literature is the applicable method. |
| Identity | supported Ward et al. introduce BSoil and publish the exact stored value for the two UK study configurations; the stable path, raw origin and legacy ID preserve that migration identity. |
Ward et al. are the checked source that introduces the BSoil class and publishes the exact 0.94 model parameter. Järvi et al. (2011) contain no bare-soil column, so Ward's general statement that emissivities came from Järvi does not apply to this newly implemented BSoil cell. Ward instead states that the BSoil emissivity was based on Oke, whose original table supports a soil interval of 0.90 to 0.98 but not the exact 0.94 selection. The record therefore retains Ward as parameter source and records Oke as upstream range evidence. Its value, stable path, raw origin and legacy ID remain unchanged; site reach reflects its documented use in the London and Swindon study configurations rather than a regional determination.
