Impact of temporal resolution of precipitation forcing data on modelled urban-atmosphere exchanges and surface conditionsParameter source

Where: Section 2.1, Equations 3 and 4, p. 651

Equation 4 is the non-vegetated drainage formulation and gives D0 10 mm h-1 and b 3; Equation 3 is the distinct vegetated formulation.

Where: Table 1, paved-surface parameters, p. 652

The Paved column gives threshold for wet evaporation 0.60 mm.

Where: SUEWS 2017b SUEWS_NonVeg.txt, Swindon paved row

Row 551 stores DrainageEq 3, DrainageCoef1 10, DrainageCoef2 3 and WetThreshold 0.6.

Multi-season eddy covariance observations of energy, water and carbon fluxes over a suburban area in Swindon, UKLater compilation

Where: Table 1, land cover within 500 m of the flux mast, p. 4647

The suburban Swindon study area is characterised within a 500 m radius, supporting the existing site-scale classification but not the drainage values.

Assessment findings

Namesupported
Paved corresponds to Ward et al.'s non-vegetated paved surface class.
Targetsupported
The drainage equation, coefficients and wet threshold are parameters of the paved surface.
Valuessupported
Ward et al. give non-vegetated surfaces D0 10 mm h-1 and b 3, and Table 1 gives paved wet threshold 0.60 mm; the official SUEWS 2017b Swindon paved row independently carries equation 3, 10, 3 and 0.6.
Sourcesupported
Ward et al. (2018) directly state the corrected drainage formulation and parameter values; Ward et al. (2013) do not publish a drainage tuple.
Placesupported
The parameter set is used for the Swindon paved surface in the official SUEWS release, and Ward et al. (2013) document the Swindon study context retained by this legacy record.
Representativenesssupported
Site representativeness matches the suburban study area characterised within 500 m of the flux mast.
Methodsupported
The stored tuple is taken from a published model formulation and its released SUEWS input, so literature is the supported method.
Identitysupported
One internally consistent non-vegetated drainage tuple is associated with the legacy Swindon paved record.

Scientific note

The legacy record path and origin retain the 2013 study association, but Ward et al. (2013) publish no drainage tuple. Ward et al. (2018) distinguish the non-vegetated drainage equation from the vegetation equation and support the corrected 10 and 3 coefficients together with a 0.60 mm paved wet threshold. The official SUEWS 2017b Swindon row independently confirms the complete tuple. The prior 0.013 and 1.71 pair belonged to the vegetation formulation and was not valid for this paved record.
