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 cityInput observations

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.

Carbon sequestration potential of street tree plantings in HelsinkiParameter source

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

Where: Table 2, model parameters for the Viikki street-tree site, p. 2127

Publishes the fitted beta 8.3463 and respiration coefficients 0.78 and 0.08 used for the Viikki Tilia street-tree site.

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 et al. (2022) Table 2 publishes the exact fitted beta and respiration coefficients for the Viikki Tilia street-tree site; the later Havu configuration reproduces them. Bellucco supports alpha and theta; Järvi supports the 0.6 floor.
Sourcesupported
Parameter-level provenance now assigns beta and respiration to Havu et al. (2022), alpha and theta to Bellucco, and the minimum respiration floor to Järvi. Havu et al. (2024) remains the record-envelope source for the released Helsinki configuration.
Placesupported
The fitted street-tree leaves come from the Viikki Tilia site, Bellucco's light-response fit comes from another Helsinki site, and the respiration floor comes from central Finland.
Representativenesssupported
Each production source is site-scoped; no fitted or assumed 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. Havu et al. (2022) publish the fitted beta and respiration coefficients for the Viikki street-tree site; Havu et al. (2024) reproduce that configuration; Bellucco publishes alpha and theta for another Helsinki site; and Järvi publishes the 0.6 floor from central-Finland site evidence. Leaf scope overrides prevent those production sites from inheriting the later Helsinki city configuration.
