CO2 Fluxes over Plant Canopies and Solar Radiation: A ReviewParameter source

Applies to: parameters.alpha_bio_co2, parameters.beta_bio_co2

Where: Table 2.1, instantaneous all-data-set rectangular-hyperbola fit, p. 24

For 1,362 observations across the complete grouped closed-canopy dataset, the table gives F-infinity 43.35, apparent quantum yield alpha 0.044 and dark-respiration intercept 4.29.

Where: Eq. 29, complete instantaneous closed-canopy dataset, p. 37

Publishes the rectangular-hyperbola numerator and denominator with alpha 0.044 and saturation parameter 43.35; the separate fitted intercept is 4.29 and is not the stored temperature-response pair.

Measurements of CO2 and Energy Fluxes over a Mixed Hardwood Forest in the Mid-Western United statesParameter source

Applies to: parameters.resp_a, parameters.resp_b

Where: Eq. 5, ecosystem respiration versus soil temperature, p. 369

Publishes RE = 1.08 exp(0.064 Ts), the exact respiration pair mechanically reused in this compiled plant-canopy tuple.

Measurements of CO2 and Energy Fluxes over a Mixed Hardwood Forest in the Mid-Western United statesValidation

Where: Sect. 2, Site and instrumentation, p. 358

Locates the respiration fit at the Morgan-Monroe State Forest tower in south-central Indiana.

Spatial Modeling of Local-Scale Biogenic and Anthropogenic Carbon Dioxide emissions in HelsinkiParameter source

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 the 0.60 minimum from chamber observations in a southern Finland boreal forest.

SUEWS database pre-migration workbook: database.xlsxLater compilation

Where: database.xlsx, Biogen CO2 sheet, row ID 30240007

Carries Plant canopies, origin UK, SE England, alpha 0.044, beta 43.35, resp_a 1.08, resp_b 0.064, min_respi 0.6, three -999 inactive fields and Ref 90240043 in one compiled row.

Assessment findings

Namesupported
Ruimy et al. analyse CO2 flux over closed plant canopies, and the migrated row preserves the concise name Plant canopies.
Targetsupported
The publication fits a surface-agnostic response across closed plant canopies, matching the migrated land_cover.common target.
Valuessupported
Ruimy Table 2.1 and Eq. 29 directly give alpha 0.044 and beta 43.35. Schmid Eq. 5 directly gives resp_a 1.08 and resp_b 0.064. Järvi Eq. 11 and Appendix B publish the later 0.60 minimum-respiration floor. The pre-migration row is the exact five-value compilation.
Sourcesupported
Ruimy is the source for alpha and beta only. Parameter-level overrides identify Schmid for the respiration pair and Järvi for the minimum floor; the workbook records compilation lineage rather than supplying scientific evidence.
issue #373
Placesupported
Ruimy pools heterogeneous closed-canopy datasets from many sites and vegetation classes, so the envelope is generic rather than south-east England evidence. The Schmid and Järvi leaf overrides preserve their separate Indiana and Finland study sites.
Representativenesssupported
Ruimy offers the grouped fit as a general closed-canopy relationship, while the borrowed respiration fit and winter floor each remain explicitly site-scoped at leaf level.
Methodsupported
Ruimy and Schmid publish fitted coefficients. The Järvi override records the later measured chamber statistic used as the minimum-respiration floor.
Identitysupported
Biogen CO2 row 30240007 preserves the exact name, origin, five active values, three -999 inactive fields and reference ID 90240043. The stable path and verbatim origin retain that migration identity while place and representativeness now describe the actual evidence reach.

Scientific note

The stored tuple is traceable but is not one publication's result. Ruimy et al. supply the generic closed-canopy light-response fit; Schmid et al. supply the temperature-response pair from an Indiana hardwood forest; Järvi et al. later supply the 0.6 winter floor from Finnish chamber observations; and the pre-migration workbook combines them. Field-level provenance now preserves those roles without changing any value, raw legacy origin, stable path or legacy identity. The former south-east England evidence scope was a workbook attribution, not a claim supported by Ruimy et al.
