CO2 uptake of urban vegetation in a warming Nordic cityParameter source

Where: Supplement Table 1, updated LAI parameterisation for deciduous trees, p. 1

Publishes growth coefficients 0.04 and 0.002 and senescence coefficients -1.5 and 0.0005 for the updated deciduous-tree parameterisation.

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

Where: Zenodo Input_met.zip/Input_met/SUEWS_Veg.txt, deciduous-tree codes 831-834

Applies LAIEq 1 with growth_lai 0.04, growth_gdd 0.002, senescence_lai -1.5 and senescence_sdd 0.0005 to all archived Helsinki deciduous-tree configurations.

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
Supplement Table 1 publishes the four updated deciduous-tree coefficients, and archived vegetation codes 831-834 store the same values with LAIEq 1 exactly.
Sourcesupported
Havu et al. directly publish the deciduous-tree tuple in the supplement. The citable Zenodo model input independently proves that the published tuple is the one used by every Helsinki deciduous-tree configuration.
Placesupported
The archived vegetation rows identify the tuple as a Helsinki model configuration.
Representativenesssupported
City records the reach of the archived Helsinki model configuration, not a claim that the coefficients were independently fitted across the city.
Methodsupported
Literature records direct transcription of the published and archived parameterisation; no undocumented transformation or new database fit is required.
Identitysupported
Stable path, target, source and values identify one retained database record.

Scientific note

The apparent source gap was caused by a generic audit note that discussed soil fields rather than this LAI record. Havu Supplement Table 1 directly publishes the complete deciduous-tree tuple, and the citable archive applies it unchanged to codes 831-834. No value, path, place or legacy identity is changed.
