emis | 0.95 |
Where: Table 2(a), Building column, emissivity row, p. 223
Publishes the exact SUEWS Building emissivity epsilon_i = 0.95 and marks the cell with footnote f to Oke (1987).
Where: Table 8.2, radiative properties of typical urban materials and areas, p. 281
Gives mid-latitude urban areas an emissivity range of 0.85-0.96 and an average of approximately 0.95. This is the upstream literature behind Järvi et al.'s footnote, but it does not itself map the value to the SUEWS Building class.
Where: Table 4(a), Building column, emissivity row, p. 1701
Later repeats Building emissivity 0.95; the caption says unfootnoted values use the sources in Järvi et al. (2011).
| Name | supported Building is the surface-class heading under which Järvi et al. publish the parameter. |
|---|---|
| Target | supported Emissivity is tabulated as a land_cover.bldgs parameter. |
| Values | supported The record stores emis 0.95, the Building-column value in Järvi et al. (2011) Table 2(a) and Järvi et al. (2014) Table 4(a). It previously stored the pavement value 0.91; issue 183 corrected that transposition. issue #183 |
| Source | supported Järvi et al. (2011) are the earliest checked publication that maps the exact 0.95 value to the SUEWS Building class. Their footnote points to Oke (1987), whose Table 8.2 gives an average urban-area emissivity of approximately 0.95 but does not publish a SUEWS building-class parameter. Järvi et al. (2014) later repeat the mapped value. |
| Place | supported The supporting tables present a model surface-class or mid-latitude urban-area value, not a Helsinki determination, so generic is the supported evidence scope. The stable path and origin retain migration lineage. |
| Representativeness | supported The evidence supports a generic parameter rather than a site, city or regional empirical determination. |
| Applicable Scale | supported Järvi et al. tabulate the value for the Building surface class, so land_cover is the supported application scale. |
| Method | supported The database adopts a published model parameter without performing a new measurement or fit. |
| Identity | supported Both papers publish separate Building and Pavement cells. The records therefore remain separate even though issue 183 found that their migrated values had been transposed. |
Järvi et al. (2011) Table 2(a) is the earliest checked publication that states the exact 0.95 as the SUEWS Building-class emissivity. Oke (1987) Table 8.2 is its explicitly cited upstream literature and gives approximately 0.95 for the average mid-latitude urban area, but the SUEWS surface-class mapping is made by Järvi et al. The canonical source is therefore jarvi2011, while the sidecar retains the Oke lineage. Järvi et al. (2014) later repeat the value. The record now describes a generic land-cover literature parameter while preserving its stable path, origin and legacy identity. No value changes.
