Applies to: parameters.lai.lai_power.growth_lai, parameters.lai.lai_power.growth_gdd, parameters.lai.lai_power.senescence_lai, parameters.lai.lai_power.senescence_sdd
Where: Appendix A, Leaf area index, Equation A1, p. 1707
Publishes growth coefficients 0.04 and 0.001 and senescence coefficients -1.5 and 0.0015, changed after comparison with visual leaf-on and leaf-off timing at Helsinki and Montreal.
Applies to: parameters.lai.lai_type
Where: LAIEq and Leaf Growth/Off Power entries, p. 88
Defines LAIEq 1 as the Järvi et al. 2014 formulation and lists its characteristic power coefficients, distinguishing it from LAIEq 0.
Where: SUEWS v2016a release workbook, SUEWS_Veg sheet, codes 553 and 663
Stores the exact selector and four coefficients for the Swindon and London grass applications.
Where: Section 4.1, Seasonal cycle of vegetation phenology, p. 7
Evaluates the Järvi 2014 phenology formulation using vegetation photographs at London and Swindon and changes the UK base temperatures, not the four LAI-power coefficients.
| Name | supported The label identifies the grass UK application of the Järvi LAI-power formulation; the official documentation identifies its selector as LAIEq 1. |
|---|---|
| Target | supported The Järvi formulation is published for vegetated SUEWS surfaces, and the v2016a application table assigns this exact tuple to the London and Swindon grass codes. |
| Values | supported Appendix A publishes all four power coefficients, the official documentation identifies selector 1, and the v2016a codes preserve the complete five-field tuple for both UK sites. |
| Source | supported Järvi et al. are the original source of the four fitted coefficients. The selector is separately attributed to the official SUEWS documentation rather than being folded into the paper citation. |
| Place | supported The SE England envelope records the exact London and Swindon application preserved by v2016a and evaluated by Ward et al.; it does not claim the coefficients were derived regionally. |
| Representativeness | supported Ward et al. evaluate the formulation at the two neighbourhood-scale study sites, so site is the supported application reach; regional determination is not established. |
| Applicable Scale | supported Equation A1 defines LAI for surface type i, so the coefficients describe a SUEWS land-cover class rather than a whole neighbourhood or individual specimen. |
| Method | supported Järvi et al. changed the coefficients after comparing simulated leaf-on and leaf-off timing with visual surveys, explicitly noting that no direct LAI measurements were available; fitted records this calibration-like origin. |
| Identity | supported The stable path and legacy ID retain the UK grass application identity while the split selector provenance preserves the source-coherent scientific tuple. |
Järvi et al. publish the four fitted LAI-power coefficients; the official SUEWS documentation establishes selector 1; and the v2016a table plus Ward et al. document their exact London and Swindon application. The record retains SE England as the shared application geography but narrows evidence reach to site and records land-cover applicability. No value, stable path, name, target, origin or legacy ID changes.
