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

Applies to: parameters.beta_bio_co2, parameters.resp_a, parameters.resp_b

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

Publishes the combined deciduous-tree and lawn inputs; Appendix B.5 explains that these parameters were calculated by weighting the component vegetation classes.

Modelling the biogenic CO2 exchange in urban and non-urban ecosystems through the assessment of light-response curve parametersParameter source

Applies to: parameters.alpha_bio_co2, parameters.theta_bio_co2

Where: Table 4, Helsinki local light-response parameters, p. 6

Publishes alpha 0.031 and theta 0.723 from one Botanical Garden eddy-covariance sector in Helsinki.

Spatial Modeling of Local-Scale Biogenic and Anthropogenic Carbon Dioxide emissions in HelsinkiParameter source

Applies to: parameters.min_res_bioco2

Where: Equation 11 and Appendix B, minimum respiration, p. 5

Publishes the 0.6 minimum respiration floor from winter chamber measurements at a boreal-forest site in central Finland.

Assessment findings

Namesupported
The label identifies the published parameter class or model configuration.
Targetsupported
The source uses the parameter for the same SUEWS target represented by the record.
Valuessupported
Havu Table B.1 and Appendix B.5 publish the calculated deciduous-tree and lawn beta and respiration combination; Bellucco supports alpha and theta; Järvi supports the 0.6 floor.
Sourcesupported
Parameter-level provenance now assigns the calculated beta and respiration combination to Havu, alpha and theta to Bellucco, and the minimum respiration floor to Järvi.
Placesupported
The calculated combination remains a Helsinki configuration; leaf overrides locate Bellucco's light-response fit at its Helsinki site and the respiration floor at its central-Finland site.
Representativenesssupported
The Bellucco fit and Järvi floor are site-scoped rather than inheriting the city reach of the calculated Helsinki configuration.
Methodsupported
The record-level literature method describes adoption of the published Havu configuration. Parameter overrides identify beta and respiration as calculated combinations, alpha and theta as fitted, and the winter respiration floor as an explicit model assumption.
Identitysupported
Stable path, target, source and values identify one retained database record.

Scientific note

Parameter-level provenance now records the mixed tuple without changing any value or stable identity. Havu publishes the calculated deciduous-tree and lawn beta and respiration combination, Bellucco publishes alpha and theta for one Helsinki site, and Järvi publishes the 0.6 floor from a central-Finland site. Leaf scope overrides preserve those production scopes without changing the later Helsinki city configuration.
