Where: SUEWS v2016a SUEWS_OHMCoefficients.txt, codes 50-55
Preserves codes 50-53, labels code 55 as their average, and stores the exact code-55 output 0.355, 0.335 and -35.275.
Where: Table 4, four bare-soil OHM rows, p. 932
Compiles the four input triplets represented by legacy codes 50-53.
Current atomic record for legacy code 50, with values 0.38, 0.56 and -27.3.
| Name | supported The fixed v2016a table identifies legacy code 55 as the bare-soil average of codes 50-53 and carries the sample-run display label preserved by this migrated record. |
|---|---|
| Target | supported All four inputs and the code-55 output are OHM coefficient triplets for the bare-soil surface category. |
| Values | supported The fixed v2016a artifact publishes the exact output tuple 0.355, 0.335 and -35.275. The displayed input rows reproduce a1 and a3 exactly; their displayed a2 mean is 0.3325 rather than 0.335, so the stored a2 is supported as the preserved code-55 release value, not as newly recomputed precision. issue #283 |
| Source | supported Unreferenced is correct because the record is an internally compiled output. Grimmond and Oke provide the input table, while the SUEWS release artifact, not a parameter publication, provides the exact code-55 tuple. |
| Place | not applicable |
| Representativeness | not applicable |
| Applicable Scale | supported Code 55 is compiled from four bare-soil surface-type inputs before any areal aggregation, so its supported unit is the bare-soil land-cover class. issue #46 |
| Method | supported Calculated distinguishes this compiled average from a measured or fitted parameter set. The sidecar records all four inputs and the visible a2 discrepancy rather than manufacturing absent atomic records or silently changing the release value. |
| Identity | supported The stable path, name, legacy ID and tuple preserve the distinct v2016a code-55 configuration row. Retaining the sample-run wording records migration lineage and does not present it as literature evidence. |
arithmetic_mean · For each component: (code50 + code51 + code52 + code53) / 4; the fixed release retains code55 a2 = 0.335 although its displayed inputs yield 0.3325. · The displayed inputs yield a1 0.355 and a3 -35.275 exactly. The a2 discrepancy is preserved and made explicit rather than resolved by changing either a source input or the release output.
The fixed SUEWS artifact is authoritative for the migrated code-55 output and identity; Grimmond and Oke are input-data evidence, not the publication of that exact output. Codes 51-53 are represented as external derivation inputs rather than artificial database records. The visible a2 inputs average to 0.3325, so the retained 0.335 is explicitly a historical release value whose extra 0.0025 is not reconstructed from the displayed rows.
