Where: ModelRuns/Input/SUEWS_BiogenCO2.txt, code 33
Carries the stored tuple and is commented Modified from Ossinlampi, Kumpula grassland.
Where: ModelRuns/Input/SUEWS_Veg.txt, code 993, columns BiogenCO2Code
Points the Beijing surfaces at biogenic code 33.
Where: ModelRuns/Input/SUEWS_SiteSelect.txt, Beijing grid 1 (2015 and 2016)
Assigns Code_EveTr 991, Code_DecTr 992, Code_Grass 993 and IrrigationCode 5 to the modelled Beijing grid, so those rows are the ones the published runs used.
Applies to: parameters.beta_bio_co2
Where: Table 2, SUEWS biogenic model parameters used for all case runs, p. 4559
Publishes Fpho,max, ai and bi with their credits; alpha and theta are absent from the article.
Where: Eq. (15), soil and vegetation respiration, p. 4554
States that 0.6 umol m-2 s-1 is the minimum respiration in winter time.
Where: Appendix D, Fitting the maximum photosynthetic rate for the grass and lawn vegetation type, p. 4572
Locates the eddy covariance lawn in Espoo, Finland, describes the nonlinear least-squares and bootstrap fit, reports Fpho,max = 5.497 +/- 0.110 umol m-2 s-1, and states that this value is used for grass and lawn in the Beijing simulation.
Applies to: parameters.alpha_bio_co2
Where: ModelRuns/Input/SUEWS_BiogenCO2.txt, code 33, alpha column
The pinned model input is the only located artifact that states alpha 0.031 for this exact grass row; the journal article does not publish alpha.
Where: Sect. 3, Study site and measurements, p. 4554
The model domain is a 1 km circle around the IAP tower, covering roughly 80 % of the accumulated flux footprint; no city-wide domain is modelled.
Applies to: parameters.resp_a, parameters.resp_b, parameters.min_res_bioco2
Where: Table A1, grass respiration parameters for Torni, p. 15
Publishes agrass = 2.1 +/- 0.8 and bgrass = 0.06 +/- 0.03 for the Torni Helsinki site, which Zheng adopts in its released configuration.
Where: Eq. 11 and accompanying text, p. 5
Sets the 0.6 umol m-2 s-1 floor from winter soil-chamber measurements in a boreal forest in central Finland.
| Name | supported The row is the grass entry of the archived Beijing run. |
|---|---|
| Target | supported Veg code 993 of the modelled Beijing grid points at biogenic code 33. |
| Values | supported Code 33 of SUEWS_BiogenCO2.txt carries alpha 0.031, beta 5.4973, resp_a 2.1, resp_b 0.06 and min_respi 0.6, which is the record exactly, and Veg code 993 points at it. Appendix D reports the fitted median Fpho,max = 5.497 +/- 0.110, so the archive carries one digit more than the article publishes. Järvi Table A1 gives grass a = 2.1 and b = 0.06 for Torni and Eq. 11 documents the 0.6 minimum; Zheng Table 2 adopts those respiration values and rounds Fpho,max to 5.5. The stored alpha appears only in the archive, and the quarantined theta of -999 matches the archive's empty column. |
| Source | supported Parameter-level provenance now keeps Zheng et al. as the source for the archive-only alpha and their fitted Espoo beta, while assigning Järvi et al. to the adopted Torni grass respiration coefficients and Finnish respiration floor. Zheng remains the record-envelope source for the exact Beijing run configuration. issue #331 |
| Place | supported The envelope place is Espoo, where Appendix D fits beta. Parameter overrides locate the adopted respiration pair at Torni in Helsinki and the minimum floor at its central-Finland chamber site. The stable Beijing path and origin retain the later application lineage. |
| Representativeness | supported Site is the supported scope for every leaf: Appendix D uses one 0.7 ha Espoo lawn, Table A1 reports the Torni site fit, and the floor comes from one central-Finland chamber site. |
| Method | supported The record-level literature method describes adoption of the published Zheng run configuration. Parameter overrides identify beta and the Järvi respiration coefficients as fitted, the respiration floor as an explicit model assumption, and the archive-only alpha as a literature configuration value. |
| Identity | supported Biogenic code 33 is a distinct row in the archive and the stored tuple is distinct from the other Beijing biogenic record in the database. |
The active place and scope identify the Espoo lawn where Zheng et al. fitted beta, rather than the Beijing application. The stable Beijing path, origin lineage, target, values, envelope source and legacy identity remain unchanged. Parameter-level provenance now records the mixed tuple without overclaiming: Zheng et al. publish the fitted Espoo beta and the archive-only alpha in their released configuration, while Järvi et al. publish the adopted Torni respiration coefficients and set the 0.6 respiration floor from a central-Finland winter soil-chamber site. Leaf-level place and scope overrides keep those production sites distinct from the Espoo beta fit.
