Provenance evidence

Awaiting sign-off

Published value · assessed by provenance-audit · 2026-09-01. Agent assessment is evidence preparation, not human verification.

CO2 uptake of urban vegetation in a warming Nordic cityParameter source

Where: Table B.1, site characteristics and model parameters used for Helsinki, p. 11

Publishes vegetation-class soil, photosynthesis, conductance, LAI and respiration inputs used for the Helsinki simulations.

Assessment findings

Namesupported
The display name identifies the Grass class in Table B.1 without retaining the stale SE England label; the canonical place separately records Helsinki.
Targetsupported
The source uses the parameter for the same SUEWS target represented by the record.
Valuessupported
The cited locator publishes the stored values at the available precision.
Sourcesupported
The cited source is a direct parameter publication or an explicit published model-input table.
Placesupported
The place agrees with the source scope or is explicitly generic.
Representativenesssupported
The declared evidence reach does not exceed the source scope.
Methodsupported
The production or literature-compilation method is stated in the source.
Identitysupported
The stable path and origin retain migration lineage, while the display name, Helsinki place, source and values identify the current evidence record without claiming a south-east England scope.

Scientific note

Table B.1 exactly supports LAImin 1.6 and LAImax 5.9 for Helsinki grass. The display name now states the supported surface class, while the stable path and origin preserve migration lineage.
