Derivation of an urban materials spectral library through emittance and reflectance spectroscopyParameter source

Where: Appendix C, Table C.1, specimen C002, p. 210-211

Lists C002 as grey/white concrete, new with measured emissivity 0.92; the sample collection is from London urban impervious materials.

Assessment findings

Namesupported
Grey/white concrete, new matches the material description for specimen C002 in Table C.1.
Targetsupported
Specimen C002 is an impervious concrete surface material, so its emissivity belongs under land_cover.paved.
Valuessupported
Table C.1 reports emissivity 0.92 for specimen C002, exactly matching the stored value.
Sourcesupported
Kotthaus et al. directly report the measured emissivity and specimen metadata for C002, so kotthaus2014 is the parameter source.
Placesupported
The source and SLUM collection identify C002 as a London urban-material specimen; place london replaces the unsupported generic place.
issue #240
Representativenesssupported
The value is one measured specimen, so site is the supported scope; the paper does not establish it as a generic material constant.
issue #240
Methodsupported
The emissivity is a specimen measurement tabulated by Kotthaus et al., so measured is the supported method.
Identitysupported
The description and value identify source specimen C002 unambiguously within Table C.1.

Scientific note

The stored emissivity is unchanged because it exactly matches specimen C002. The correction is scope; a measurement of one London specimen is London/site evidence, not a place-independent generic constant.
