Applies to: parameters.beta_bio_co2, parameters.resp_a, parameters.resp_b
Where: Supplement Table S3, Parameters used by SUEWS model, Lawn column, p. 3
Directly gives Fpho,max 8.92, ai 1.7 and bi 0.06 for Lawn; these map to beta_bio_co2, resp_a and resp_b.
Where: Zenodo parameter table, Parameters used by SUEWS model, Lawn column
The open model archive repeats the exact 8.92, 1.7 and 0.06 parameter set used for the Zurich lawn simulations.
Where: Abstract and Sect. 2.1, study sites, p. 2133
Evaluates the models against in-situ observations from lawns and trees in four urban parks in Zurich; it does not establish a city-wide lawn parameter fit.
Applies to: parameters.alpha_bio_co2, parameters.theta_bio_co2
Where: Table 4, mean 200-270 degree vegetated sector, p. 118
Publishes the Helsinki local-model non-rectangular-hyperbola coefficients alpha 0.031 and theta 0.723, averaged over the botanical-garden wind sector and used in the final local model.
Applies to: parameters.min_res_bioco2
Where: Eq. (11), soil and vegetation respiration, p. 8366
Defines respiration as max(a_i exp(Tair b_i), 0.6) for each vegetated surface.
Where: Appendix B, Estimating Minimum Soil Respiration, p. 8379
Reports a 0.60 +/- 0.07 micromol m-2 s-1 minimum from 1,677 cold-season half-hour observations measured by three automatic soil chambers in a Southern Finland boreal forest.
Where: Table B.1, Grass column, p. 11
Gives Grass Fpho,max 5.3, a 1.2 (2.1 for mixed low vegetation), and b 0.09 (0.06 for mixed low vegetation), not the exact Stagakis Lawn triple 8.92, 1.7 and 0.06.
Where: Appendix B.4, Low vegetation, p. 12
Describes the Helsinki lawn and mixed-low-vegetation fitting data and makes clear that the published grass and mixed-low-vegetation values are distinct parameterizations.
| Name | supported Grass corresponds to the Lawn column of Stagakis Supplement Table S3. |
|---|---|
| Target | supported All six leaves are photosynthesis or respiration properties of the SUEWS grass land-cover class. |
| Values | supported Stagakis Table S3 directly publishes beta_bio_co2 8.92, resp_a 1.7 and resp_b 0.06 for Lawn. Bellucco Table 4 directly publishes the fitted Helsinki local-model alpha 0.031 and theta 0.723. Järvi Eq. (11) and Appendix B publish the 0.6 minimum respiration floor. Havu Table B.1 does not publish the exact Stagakis lawn triple, so its citation in Table S3 is retained as lineage rather than substituted for the artifact that states the stored values. |
| Source | supported Stagakis is the direct parameter source for beta_bio_co2, resp_a and resp_b. Canonical field-level overrides identify Bellucco for alpha_bio_co2 and theta_bio_co2 and Järvi for min_res_bioco2. Havu is not promoted to parameter source because its published grass tuple differs from the three exact values used by Stagakis. issue #217 |
| Place | supported Zurich is the application place for the Stagakis lawn configuration. The alpha and theta overrides preserve their Helsinki fit location, while the minimum-respiration override preserves the Southern Finland chamber evidence instead of making either value appear Zurich-derived. |
| Representativeness | supported Stagakis evaluates a common lawn configuration at four individual parks, Bellucco fits one Helsinki flux site and Järvi derives the floor from one chamber site. Site is the supported evidence reach at both record and overridden-field levels. |
| Method | supported Literature is the record-level method because Stagakis adopts the three exact lawn values in its model configuration. The alpha and theta overrides are fitted non-rectangular-hyperbola coefficients, and the minimum-respiration override is the measured winter chamber statistic that Järvi later installs as the model floor. |
| Identity | supported The six-leaf lawn tuple is distinct from the tree biogenic configurations and retains its stable path, values and legacy row identity. |
The record is a mixed-source but fully traceable SUEWS lawn configuration. Stagakis directly publishes the three values it used for the Zurich runs. Bellucco supplies the earlier Helsinki light-response fit for alpha and theta, and Järvi supplies the separately measured winter respiration floor. Per-leaf provenance preserves those source, method and place distinctions without changing any numeric value or pretending that Havu's different published grass tuple is the exact source of the Stagakis values.
