Where: Table 4, measured commercial/industrial gravel roof — dry, wind 1.5-2.0 m s-1, p. 750
Average of three days of measurements on the UBC University Services building; 0.23, 0.87 h, -24 W m-2.
Uses code 703 with six other Meyn rows and code 713 in its documented arithmetic mean.
| Name | supported Table 4 identifies a commercial or industrial gravel roof under dry conditions with wind 1.5-2.0 m s-1; code 703 is retained legacy identity. |
|---|---|
| Target | supported The source reports objective-hysteresis coefficients for roof heat storage. |
| Values | supported Table 4 states a1 0.23, a2 0.87 h and a3 -24 W m-2 exactly. |
| Source | supported Meyn and Oke directly publish the complete fitted tuple. |
| Place | supported The measured roof sites are on the University of British Columbia campus in Vancouver. |
| Representativeness | supported The coefficients are derived from specific monitored roofs, supporting site scope. |
| Applicable Scale | supported Meyn and Oke fit each tuple to a specific monitored commercial/industrial or residential roof under the stated surface and weather condition, establishing roof-facet scale. issue #46 |
| Method | supported The table reports averages of regression coefficients fitted to hourly measured Q-star and roof conductive heat flux. |
| Identity | supported The material, wetness, wind class and exact tuple identify one Table 4 row; the related Helsinki record uses it as an arithmetic-mean input. |
The record is a direct, source-coherent transcription of one Table 4 regression row derived from measured fluxes. No canonical field changes.
