Where: Sect. 2, Site and instrumentation, p. 358
Locates the Morgan-Monroe State Forest tower at 39 degrees 19 minutes N, 86 degrees 25 minutes W in an extensive secondary-successional broadleaf forest, with minimum fetch 4 km.
Applies to: parameters.alpha_bio_co2, parameters.beta_bio_co2, parameters.resp_a, parameters.resp_b
Where: Eq. (5), ecosystem respiration versus soil temperature, p. 369
Publishes RE = 1.08 exp(0.064 Ts), with flux in micromol m-2 s-1 and Ts in degrees C.
Where: Eq. (6), gross ecosystem production versus PPFD, p. 370
Publishes GEP = -1.4 + 35 PPFD / (590 + PPFD). Thus beta is 35 and the initial slope of the saturating component is 35 / 590 = 0.059322, rounded to 0.0593.
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 half-hour observations during 2009-2012 below -2 degrees C, measured by three automatic soil chambers in a Southern Finland boreal forest. Pumpanen et al. (2015) is cited for chamber methods, not for the 0.60 statistic.
Where: database.xlsx, Biogen CO2 sheet, row ID 30240008
Carries Mixed Hardwood Forest, origin Midwest America, alpha 0.0593, beta 35, resp_a 1.08, resp_b 0.064, min_respi 0.6, three -999 inactive fields and Ref 90240042 in one compiled row.
| Name | supported Schmid et al. study a mixed secondary-successional broadleaf forest, and the migrated row preserves the name Mixed Hardwood Forest. |
|---|---|
| Target | supported The article derives ecosystem photosynthesis and respiration terms for vegetation, while the migrated row explicitly classifies the tuple as All vegetation, represented by land_cover.common. |
| Values | supported Schmid Eq. (5) directly gives resp_a 1.08 and resp_b 0.064. Eq. (6) directly gives the light-saturated maximum beta 35 and the half-saturation constant 590; 35 / 590 = 0.059322, which rounds to stored alpha 0.0593. Järvi Eq. (11) and Appendix B publish the later minimum respiration floor 0.60. The pre-migration row is the exact stored five-value compilation. |
| Source | supported Schmid is the effective source for alpha, beta, resp_a and resp_b. The parameter-level override identifies Järvi et al. as the distinct source for min_res_bioco2 and records its Finnish site evidence, while the workbook remains compilation lineage rather than a parameter publication. issue #372 |
| Place | supported The paper locates the flux site in Morgan-Monroe State Forest, south-central Indiana, at 39 degrees 19 minutes N and 86 degrees 25 minutes W, matching the record-level place. Järvi Appendix B locates the separate min_res_bioco2 evidence in a Southern Finland boreal forest, supporting its Finland override without implying Morgan-Monroe provenance. |
| Representativeness | supported The Schmid coefficients come from one flux-tower site and the Järvi floor from one chamber site. Site is therefore the supported evidence reach for both the envelope and the overridden leaf. |
| Method | supported The record-level fitted method applies to beta, resp_a and resp_b. The alpha override records its algebraic calculation from Schmid Eq. (6), and the min_res_bioco2 override records the later measured Finnish chamber statistic published by Järvi et al. |
| Identity | supported Biogen CO2 row 30240008 preserves the exact name, origin, five active values, three -999 legacy sentinels and reference ID 90240042. The stable path and legacy_id retain that identity; the -999 theta, alpha_enh and beta_enh entries are unavailable legacy fields, not sourced scientific values. |
The stored values are all traceable but have distinct provenance roles. Schmid et al. fit the forest light-response and respiration functions; alpha is calculated from their published beta and half-saturation constant; Järvi et al. later publish the 0.6 chamber-observation floor; and the pre-migration workbook combines them. Parameter-level provenance now preserves those roles without changing any value or stable identity and prevents the Finnish chamber statistic from inheriting the Morgan-Monroe place.
