max_conductance | 3.7 |
Where: Appendix B, Table B.1, Site characteristics and used model parameters for Helsinki, p. 11
Publishes gmax 3.7 mm s-1 in the Grass column.
Where: Appendix B, Biogenic CO2 module parameters, and B.4, Low vegetation, p. 12
Describes the observational fitting and bootstrapped least-squares procedure for the Table B.1 parameters and identifies the grass data as an urban lawn in the Helsinki metropolitan region.
Where: Section 3.4, Uncertainties in CO2 modelling, p. 10
States that the parameters were derived from EC or chamber measurements and that generalising the neighbourhood-scale results to the broader Helsinki context was acceptable.
Where: Supplement Table S3, Parameters used by SUEWS model, p. 3
Gives one Lawn column and no maximum-conductance or G1 row.
Where: Title and abstract, p. 2133
Establishes application to four Zurich urban parks.
| Name | supported Grass is the surface-class heading under which Havu et al. publish the parameter. |
|---|---|
| Target | supported Maximum vegetation conductance is tabulated for the Grass class represented by land_cover.grass. |
| Values | supported Havu et al. Table B.1 publishes grass maximum conductance as 3.7 mm s-1, exactly matching the stored value. |
| Source | supported Havu et al. is the exact parameter publication. Stagakis et al. is retained only as the later Zurich application context; its article and Supplement Table S3 publish no maximum-conductance parameter. |
| Place | supported Havu et al. publish 3.7 among the model parameters used for Helsinki and describe the grass fitting data as an urban lawn in the Helsinki metropolitan region. Helsinki is therefore the active evidence place; Zurich remains only in origin and the stable path as application lineage. |
| Representativeness | supported Havu et al. fit urban-vegetation parameters from measurements and state that generalising their neighbourhood-scale results to the broader Helsinki context was acceptable. City is therefore the supported reach; Stagakis supplies no Zurich conductance evidence. |
| Method | supported Havu et al. describe fitting the biogenic parameters collected in Table B.1 from observations, using bootstrapped least-squares procedures; fitted is the supported method. |
| Identity | supported The stable path, origin and legacy ID retain the Zurich application instance, while the canonical source, place and method now describe its Helsinki/Havu scientific evidence. The value and evidence agree with the retained Helsinki sibling rather than claiming an independent Zurich determination. |
Havu et al. Table B.1 publishes the exact 3.7 mm s-1 Grass value among the parameters used for Helsinki. Its methods describe observational fitting, bootstrapped least-squares estimation and an urban-lawn dataset from the Helsinki metropolitan region; the paper also accepts neighbourhood-to-city generalisation within Helsinki. Stagakis et al. publish no maximum-conductance parameter and supply only the later Zurich application context. The canonical record therefore uses source havu-m2024, place helsinki, representativeness city and method fitted. The stable path, origin Zurich and legacy ID retain application lineage without claiming an independent Zurich determination. No value changes.
