Provenance evidence

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 cityInput observations

Applies to: parameters.beta_bio_co2

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.

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 320

The released model-input row states beta 5.312 for the Helsinki mixed-low-vegetation configuration, preserving the single-site lawn fit at greater precision than Table B.1's printed 5.3.

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.resp_a, parameters.resp_b, parameters.min_res_bioco2

Where: Table A1, Torni grass respiration parameters, p. 15

Publishes grass respiration coefficients a 2.1 and b 0.06 for the Torni Helsinki site, adopted for the mixed-low-vegetation row.

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 5.312 at full precision, Havu Appendix B documents the lawn fit, Järvi publishes the mixed-low-vegetation respiration coefficients and 0.6 floor, and Bellucco supports alpha and theta.
Sourcesupported
Parameter-level provenance now assigns the full-precision beta to the Havu model-input archive, the respiration coefficients and floor to Järvi, and alpha and theta to Bellucco.
Placesupported
Beta and the Bellucco fit come from specific Helsinki sites, the respiration pair is the Torni Helsinki fit, and the minimum floor comes from a central-Finland site.
Representativenesssupported
Every fitted or assumed production source is site-scoped; no leaf inherits city reach from the later mixed-low-vegetation configuration.
Methodsupported
The record-level literature method describes adoption of the released Havu configuration. Parameter overrides identify beta and the 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 archive preserves the site-fitted lawn beta at full precision, Järvi publishes the adopted Torni respiration pair and central-Finland winter floor, and Bellucco publishes alpha and theta for another Helsinki site. Leaf scope overrides preserve those production sites.
