Fills all four ohm positions, summer_wet, summer_dry, winter_wet and winter_dry. The record declares target ohm_coefficients, name "Short grass [30]" and source grimmond1991b; it carries no place or representativeness field. It declares no season_label, so one set fills all four positions.
Fills the porosity slot structurally. The assumed, unreferenced "Dummy value" adapter has an empty parameters mapping and only preserved legacy -999 sentinels, so it contributes no active parameter and makes no literature-value claim.
Fills the biogen_co2 slot. The record declares target land_cover.grass, name "Grass (lawn)", place helsinki, representativeness city and source havu-m2024.
Fills the leaf_growth_power slot. The record declares target land_cover.grass, name "Grass, LaiEq = 1", place helsinki, representativeness city and source havu-m2024-data.
Fills the max_vegetation_conductance slot. The record declares target land_cover.grass, name "Grass", place helsinki, representativeness city and source havu-m2024.
Fills the vegetation_growth slot. The record declares target land_cover.grass, name "Grass", place helsinki, representativeness city and source jarvi2014.
Fills the snow_lim_patch slot. The stable path and origin retain Helsinki migration lineage, while the record declares target land_cover.grass, name "Grass", place generic, representativeness generic, applicable_scale land_cover, source jarvi2014 and method literature.
Fills the albedo slot. The record declares target land_cover.grass, name "Grassland/herbaceous", place generic, representativeness generic, source vargo2013 and method literature.
Fills the drainage slot. The record is the generic, land-cover-scale Grass tuple published by Järvi et al.; Havu's archive is retained as later Helsinki compilation evidence.
Fills the leaf_area_index slot. The record declares target land_cover.grass, name "Grass (SE England)", place helsinki, representativeness city and source havu-m2024. Its stable path, name and origin retain the legacy SE England migration text.
Fills the emissivity slot. The record declares target land_cover.grass, name "Grass", place generic and representativeness generic; it carries source jarvi2011 and declares method literature.
Fills the water_storage slot. The stable path retains SE England migration lineage, while the record declares target land_cover.grass, name "Grass", place swindon, representativeness site, source ward2018 and method literature.
| Composite identity | supported The composite's name reads "Grass (Havu et al 2024)", its place reads helsinki and its origin reads Helsinki, Finland. Three of the twelve components declare source havu-m2024, filling leaf_area_index, max_vegetation_conductance and biogen_co2; leaf_growth_power declares source havu-m2024-data. The drainage component declares jarvi2011 but is present in Havu's archived configuration. Those five slots are exactly the ones in which this composite differs from its neighbours, so the study named in the label is the one that gives the entry its identity. The remaining slots declare other sources, vargo2013 for albedo, ward2016 for emissivity, ward2018 for water_storage, jarvi2014 for snow_lim_patch and vegetation_growth, unreferenced for porosity and grimmond1991b for ohm; the label names the study the configuration follows rather than the source of every component. |
|---|---|
| Composite target | supported The composite declares target land_cover.grass. Eleven of the twelve components declare target land_cover.grass and the twelfth, records/ohm/generic--unreferenced--grass, declares target ohm_coefficients, which is what the ohm slot takes: docs/FORMAT.md puts the four season and wetness positions of supy's ohm_coef on the archetype rather than on the coefficient records. Surface records carry no attaches_to field, which in this database appears only on the profile records under records/profiles/, so the slot check rests on the parameter names each component carries, and every slot receives a component holding the fields that slot names. The ohm component is named "Short grass [30]", the grass-specific coefficient set rather than a vegetation average, and it fills all four positions because it declares no season_label and no wet or dry distinction. |
| Own parameter values | not applicable The composite declares no parameters of its own, so it overrides no component value; the exported fragment is its components merged into their slots. |
| Composition rationale | not applicable The composite declares no source field and asserts no parameters of its own, so there is no published composition rationale to review. The archetype format does allow a composite to carry a source, as the snow archetypes do for the scalars they assert themselves, and this entry carries none. Each component's own source belongs to that component's evidence assessment. |
| Place applicability | curation required The composite declares place helsinki. Five components carry that place, one site-scoped water-storage record carries place swindon, five components are generic and the OHM record carries no place. Snowpack limit and drainage are generic Järvi literature inputs. The Swindon site import needs an explicit composition rationale for this Helsinki typology. |
| Representativeness | curation required The composite declares representativeness city. Five components are city, five are generic, the Swindon water-storage record is site-scoped and the OHM record carries no class. The site result is narrower than the city typology and needs composition-level adjudication. |
| Slot and season mapping | supported An assembly of twelve existing records into the twelve slots the vegetation archetypes use, and assembled is the method a composition sidecar takes. The composite produces no value of its own. |
| Completeness and uniqueness | supported The uses block fills all twelve slots the vegetation archetypes use, namely albedo, emissivity, water_storage, leaf_area_index, leaf_growth_power, drainage, max_vegetation_conductance, porosity, biogen_co2, snow_lim_patch, vegetation_growth and ohm, which is the slot vocabulary every land_cover.grass, land_cover.dectr and land_cover.evetr archetype in the database uses, so no slot is missing. The ohm slot names one record in all four positions. The entry is not unique in its component set in the strict sense: archetypes/surfaces/grass/helsinki-finland--low-vegetation-havu-et-al-2024 takes the same eleven components and differs only in the biogen_co2 slot, where it takes records/surfaces/grass/helsinki--havu-m2024--biogen-co2--mixed-low-vegetation ("Mixed low vegetation") in place of records/surfaces/grass/helsinki--havu-m2024--biogen-co2 ("Grass (lawn)"). That single difference is the distinction the two names carry, lawn against mixed low vegetation, so the pair is a deliberate split rather than a duplication. |
The label remains honest about the Havu-defined slots. Five of the twelve components declare place helsinki; three declare source havu-m2024 and the leaf-growth-power record declares havu-m2024-data. Those four Havu records plus the Järvi-sourced drainage record present in Havu's archive are precisely the five slots in which this composite differs from its neighbours, so the entry is what its name says: the Helsinki grass configuration of that study, with its Havu leaf-area record now correctly placed in Helsinki, resting on a site-scoped Swindon water-storage value and generic emissivity, albedo and snowpack-limit inputs, with Helsinki phenology, and on an unreferenced generic porosity adapter and the Grimmond et al.-sourced OHM coefficients. Three Helsinki grass records go unused here, the two jarvi2014 drainage records and the mixed-low-vegetation biogenic CO2 record that separates this entry from its low-vegetation sibling; taking the drainage record compiled in Havu's archive rather than a jarvi2014 one keeps the composite within the study configuration while crediting the original Järvi source. This entry and archetypes/surfaces/grass/helsinki-finland--low-vegetation-havu-et-al-2024 differ in one slot only, which is the lawn against mixed-low-vegetation distinction their names carry; the drainage component is now explicitly generic literature evidence with archived Helsinki reuse. The Swindon site water-storage import still needs a written composition rationale.
