Defines the radiation-response form and its 1000 W m-2 reference, matching kmax.
Where: Equations 20-21, temperature response, p. 26
States the low and high temperature limits as 0 and 40 degrees C, matching tl and th.
Where: Equations 22-24, soil-moisture response, p. 26
Gives K10 1.08 and K11 69.7, matching s1 and s2.
The all-days row was fitted to all measurement hours from 1974, 1975 and 1976 at Thetford Forest.
| Name | supported Stewart (1988) identifies the publication and fitted conductance model represented by this record. |
|---|---|
| Target | supported Equations 9-24 define the surface-conductance model and its environmental response functions. |
| Values | supported Table 2's all-days non-linear-model row and Eqs. 17-24 reproduce every stored coefficient at the published precision. |
| Source | supported Stewart (1988) is the parameter publication that derives and reports the fitted values. |
| Place | supported The Site and measurements section places the observations near the centre of Thetford Forest, Norfolk, at 52 degrees 25 minutes N, 0 degrees 40 minutes E and 46 m altitude, matching the record and place registry. |
| Representativeness | supported The coefficients were fitted to dry-canopy observations from one instrumented Scots pine stand at Thetford Forest, so site is the source-supported evidence scale. |
| Method | supported Table 2 states that the parameters were obtained by optimisation against the Thetford Forest measurements; the record is therefore a fitted parameter set. |
| Identity | supported No exact duplicate of this coefficient set occurs in the current conductance-record inventory. |
The original article supports the current source and all eleven conductance coefficients. It establishes that the values are a site-scale parameter set fitted to dry-canopy observations from the instrumented Scots pine stand at Thetford Forest, rather than generic pine-forest coefficients.
