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.resp_a, parameters.resp_b

Where: Table B.1 and Appendix B.1, deciduous-forest parameterisation, p. 11

Publishes the forest coefficients used in the Helsinki simulation and states that the deciduous-forest fit uses Harvard Forest data in the United States.

Data used in manuscript CO2 uptake of urban vegetation in a warming Nordic cityParameter source

Applies to: parameters.beta_bio_co2

Where: Input_met/SUEWS_BiogenCO2.txt, code 301

The released model-input row states beta 9.899 for the Helsinki deciduous-forest configuration, preserving the fit at greater precision than Table B.1's printed 9.9.

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
The Havu archive states beta 9.899 at full precision, while Table B.1 and Appendix B publish the fitted forest parameters and exact respiration coefficients. Bellucco supports alpha and theta; Järvi supports the 0.6 floor.
Sourcesupported
Parameter-level provenance now assigns the full-precision beta to the Havu model-input archive, the respiration coefficients to the Havu article, alpha and theta to Bellucco, and the minimum respiration floor to Järvi.
Placesupported
Leaf overrides distinguish the Harvard Forest fit, the Helsinki Bellucco site and the central-Finland respiration-floor site from the later Helsinki model configuration.
Representativenesssupported
Every fitted or assumed production source is site-scoped; no leaf inherits the city reach of the later Helsinki configuration.
Methodsupported
The record-level literature method describes adoption of the released Havu configuration. Parameter overrides identify the photosynthesis and respiration coefficients 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. The Havu article documents the Harvard Forest fit and exact respiration pair, its released model-input archive preserves beta at full precision, Bellucco publishes alpha and theta for a Helsinki site, and Järvi publishes the 0.6 floor from central-Finland site evidence. Leaf place and scope overrides prevent those production sites from inheriting the later Helsinki city configuration.
