a1 | 0.25 Järvi 2014 |
a2 | 0.6 |
a3 | -30 |
Where: Section 3.1.2, Snow storage heat, p. 1699-1700
Sets a1 to 0.25 from the water/heat-capacity assumption and reports optimized a2 = 0.60 and a3 = -30 using the Montreal Pr site.
Where: Tables 3 and 4(b), p. 1700-1701
Table 4(b) lists the final snow OHM triplet 0.25, 0.6 and -30. Table 3 instead prints a2 = 0.5, despite the section text identifying 0.60 as the optimum.
Where: Table 1 and Section 2.2.2, Montreal site characteristics, p. 1696
Identifies Pr as the Pierrefonds–Roxboro suburban site in Montreal and locates it at 45.501 N, 73.811 W.

| Values | supported Section 3.1.2 identifies a2 = 0.60 as the optimum and Table 4(b) uses 0.6 in the final model parameter set. Table 3 prints 0.5, an internal inconsistency that does not outweigh the matching narrative and final parameter table but must remain visible to reviewers. |
| Source | supported |
| Place | supported The record declares montreal-suburban. Section 2.2.2 and Table 1 identify Pr as the suburban Montreal site in the Pierrefonds–Roxboro borough at 45.501 N, 73.811 W. Section 3.1.2 states that a2 and a3 were optimized there. The stable path and origin retain the legacy Helsinki migration text; Helsinki is one of the sites where the completed set was later applied. |
| Representativeness | supported Site representativeness is the honest evidence envelope because the observational optimization of a2 and a3 used the single Pr site. Applying the completed set at all sites describes how far the evidence travelled, not a broader place or observational scale. |
| Applicable Scale | supported Järvi et al. define this as the snow-covered surface-type OHM input used before surface-cover aggregation, establishing land-cover scale. issue #46 |
| Method | supported The record-level fitted method applies to a2 and a3, which were optimized against sensible heat. The parameter-specific assumed method on a1 records its selection from shallow-water a1 and a heat-capacity ratio. |
| Identity | supported |
The publication supports the triplet, subject to an internal inconsistency for a2. Section 3.1.2 states the optimum is 0.60 and Table 4(b) uses 0.6 in the final model parameters, whereas Table 3 prints 0.5. The record retains 0.6 because the narrative and final parameter table agree. It declares the Pr suburban site in Montreal and site representativeness because that is where a2 and a3 were optimized against observed sensible heat. The place-neutral a1 assumption does not support a different location, and the completed triplet's later use at all sites describes evidence travel rather than origin. The coefficient-specific method metadata preserves that a1 is assumed from shallow-water and heat-capacity relationships, whereas a2 and a3 are fitted.
