Evergreen treesSelected component

Fills albedo. The stable SE England-path record declares target land_cover.evetr, place generic, representativeness generic, applicable_scale land_cover, source jarvi2011 and method literature. Its path and origin preserve later UK application lineage.

Evergreen treesSelected component

Fills emissivity. The record declares target land_cover.evetr, place generic and representativeness generic, and is named "Evergreen trees"; it carries source jarvi2011 and declares method literature.

Evergreen TreeSelected component

Fills water_storage. The record declares target land_cover.evetr, place se-england and representativeness regional, and is named "Evergreen Tree"; its source field reads jarvi2011.

Evergreen Tree (SE England)Selected component

Fills leaf_area_index. The record declares target land_cover.evetr, place se-england and representativeness regional, and is named "Evergreen Tree (SE England)"; it carries source jarvi2011 and declares method literature.

Evergreen Tree (SE England)Selected component

Fills leaf_growth_power. The record declares target land_cover.evetr, place se-england, representativeness site, source jarvi2014 and method fitted. Official SUEWS documentation supplies the lai.lai_type 1 selector, matching the leaf_area_index component.

Evergreen TreeSelected component

Fills drainage. The record declares target land_cover.evetr, place se-england and representativeness regional, and is named "Evergreen Tree"; its source field reads ward2018 and its method is literature.

Evergreen Tree (SE England)Selected component

Fills max_vegetation_conductance. The record declares target land_cover.evetr, place se-england and representativeness regional, and is named "Evergreen Tree (SE England)"; it carries source breuer2003 and declares method literature.

Dummy valueSelected component

Fills porosity. The record declares target land_cover.evetr, place generic and representativeness generic, and is named "Dummy value"; its source field reads unreferenced.

Plant canopiesSelected component

Fills biogen_co2. The record declares target land_cover.common and mixed leaf-level provenance. Ruimy supplies the generic light-response pair, Schmid supplies the site-scoped Morgan-Monroe respiration pair, and Järvi supplies the site-scoped Finnish minimum-respiration floor. It is named "Plant canopies"; the cross-site selection remains a composition-level curation question.

Evergreen TreeSelected component

Fills snow_lim_patch. The stable path and origin retain Helsinki migration lineage, while the record declares target land_cover.evetr, name "Evergreen Tree", place generic, representativeness generic, applicable_scale land_cover, source jarvi2014 and method literature.

Evergreen TreeSelected component

Fills vegetation_growth. The record declares target land_cover.evetr, place helsinki and representativeness city, and is named "Evergreen Tree"; its source field reads jarvi2014.

Code 201 x Mulitplier for summer [2011]Selected component

Fills ohm.summer_wet and ohm.summer_dry. The record declares target ohm_coefficients and is named "Code 201 x Mulitplier for summer [2011]"; its source field reads ward2016, it declares season_label Summer and it declares no place or representativeness.

Code 201 x Multiplier for winter [2012]Selected component

Fills ohm.winter_wet and ohm.winter_dry. The record declares target ohm_coefficients and is named "Code 201 x Multiplier for winter [2012]"; its source field reads ward2016, it declares season_label Winter and it declares no place or representativeness.

Assessment findings

Composite identitysupported
The composite is named "Evergreen Tree Ward et al. (2016)" and declares place swindon with origin "Swindon, UK". Only its two OHM components now declare source ward2016; the label identifies configuration lineage rather than the source of every value. It is not unique to this composite: archetypes/surfaces/evetr/london-uk--evergreen-tree-ward-et-al-2016 carries the same name, and the place field is the only thing telling the two apart. That is treated under identity.
Composite targetsupported
The composite declares target land_cover.evetr. Every component declares that same target except two: biogen_co2 takes records/surfaces/common/se-england--ruimy1995--biogen-co2, declaring target land_cover.common, which docs/FORMAT.md defines as the surface-agnostic class, and the OHM positions take records declaring target ohm_coefficients. leaf_area_index and leaf_growth_power both declare lai.lai_type 1, which satisfies the leaf_area_index coupling rule in schema/parameter_groups.yml, which makes an archetype whose two LAI components carry different lai_type values internally contradictory. The season mapping is the one in this class that its components confirm: records/ohm/generic--ward2016--all-vegetation declares season_label Summer and fills summer_wet and summer_dry, and records/ohm/generic--ward2016--all-vegetation--code-201-x-multiplier-for-winter-2012 declares season_label Winter and fills winter_wet and winter_dry. Neither record declares a wetness state, so leaving the wet and dry positions identical follows what they say.
Own parameter valuesnot applicable
The composite declares no parameters of its own, so every value it delivers is the component's.
Composition rationalenot applicable
The composite claims no composition source, and the repository records no published rationale for this assembly. The components' own sources belong to their evidence assessments, not to this review.
Place applicabilitycuration required
The composite claims swindon. Albedo, emissivity, porosity, biogenic CO2 and snow limit are generic at record level; leaf area index and maximum conductance are regional SE England rows; leaf-growth power is a site-scoped SE England application; water storage and drainage are site-scoped Swindon rows; and phenology is a Helsinki row. The two Swindon site values align with the composite place, while the Helsinki selection has no published transfer rationale. snow_lim_patch takes the generic Järvi land-cover default. vegetation_growth is not forced. It takes records/surfaces/evetr/helsinki--jarvi2014--phenology, which declares place helsinki with lai.base_temperature 5 and lai.base_temperature_senescence 10, while records/surfaces/evetr/se-england--ward2016--phenology exists, declares place se-england and source ward2016 with lai.base_temperature 6 and lai.base_temperature_senescence 11, and is selected by no archetype in the database. schema/parameter_groups.yml classes the degree-day thresholds as a tight group whose members have to be chosen consistently, so a Ward et al. (2016) composite taking Helsinki base temperatures while its own region's record goes unused is a selection a maintainer should confirm or correct. The biogen_co2 slot likewise combines Ruimy's generic light-response pair with Schmid's site-scoped Morgan-Monroe respiration pair and Järvi's site-scoped Finnish minimum respiration floor, so those cross-site selections also need adjudication.
Representativenesscuration required
The composite declares representativeness city. Five record-level components are generic, two are regional, the LAI-power record and two Swindon records are site-scoped, one is city-scoped to Helsinki, and the two OHM records carry no representativeness. The biogen_co2 component has mixed scope. Ruimy's alpha_bio_co2 and beta_bio_co2 are generic, but Schmid's resp_a and resp_b and Järvi's min_res_bioco2 are site-scoped. The LAI-power record and those site results are narrower than the city composite, and no published composition rationale documents the transplant, so city representativeness needs maintainer adjudication.
Slot and season mappingsupported
An assembly of existing records into slots; the composite asserts no value of its own.
Completeness and uniquenesscuration required
The composite fills all eleven named slots and the four OHM positions, which is the slot set every deciduous-tree, evergreen-tree and grass archetype in this database uses, so the assembly is complete. The porosity slot takes records/surfaces/evetr/generic--unreferenced--porosity, whose parameters block is empty and whose origin reads "Porisity only used for Deciduous Tree. This is a Dummy Variable", so that slot contributes no value by design rather than by omission. The composite is not unique. archetypes/surfaces/evetr/london-uk--evergreen-tree-ward-et-al-2016 carries a byte-identical uses block, the identical name "Evergreen Tree Ward et al. (2016)" and no parameters of its own, so the two differ only in place and legacy_id and deliver identical values under two labels. The same duplication holds in three other surface classes, where archetypes/surfaces/bsoil/london-uk--central-london-ward-et-al-2016 and archetypes/surfaces/bsoil/swindon-uk--suburban-residential-ward-et-al-2016, archetypes/surfaces/dectr/london-uk--deciduous-tree-ward-et-al-2016 and archetypes/surfaces/dectr/swindon-uk--deciduous-tree-ward-et-al-2016, and archetypes/surfaces/grass/london-uk--grass-ward-et-al-2016 and archetypes/surfaces/grass/swindon-uk--grass-ward-et-al-2016 each share a uses block. Whether these pairs should stay as two site labels pointing at one regional parameterisation or be merged is a curation decision, and it should be taken once across the four classes.

Scientific note

This composite's label records configuration lineage rather than the source of every value: only its two OHM components now cite ward2016, while the remaining components retain their field-level sources. Its two OHM records carry season_label Summer and Winter and are mapped to exactly those positions, and its two LAI components agree on lai_type 1. The first point is the phenology: vegetation_growth takes the Helsinki record when records/surfaces/evetr/se-england--ward2016--phenology, from the composite's own region and source, exists and is used by no archetype at all, and the degree-day thresholds are a tight group in schema/parameter_groups.yml. The second is the biogen_co2 tuple, which combines Ruimy's generic fit with site-scoped Schmid respiration coefficients and a site-scoped Järvi minimum-respiration floor without a published composition rationale. The third is duplication: this composite and its counterpart carry identical uses blocks, the identical name "Evergreen Tree Ward et al. (2016)", and no parameters of their own, so they deliver identical values under two labels, and the same pairing recurs in the bare-soil, deciduous-tree and grass classes. All three questions are about selection, not about any component's value, and are better settled once across the Ward et al. (2016) archetypes than one composite at a time. Snowpack_limit is the generic Järvi land-cover default.
