The Analytical Objective Hysteresis Model (AnOHM v1.0): methodology to determine bulk storage heat flux coefficientsParameter source

Where: Table 1(a), input-parameter sensitivity distributions, p. 2880

Publishes means of 2.0 MJ m-3 K-1 for volumetric heat capacity, 1.2 W m-1 K-1 for thermal conductivity and 4 for the bulk transfer coefficient.

Assessment findings

Namesupported
BareSoil is consistent with the land_cover.bsoil target and the generic bare-soil application of the published sensitivity means.
Targetsupported
AnOHM material properties are land_cover.bsoil properties.
Valuessupported
Table 1(a) gives distribution means of 2.0 MJ m-3 K-1, 1.2 W m-1 K-1 and 4, exactly matching rho_cp_anohm 2000000, k_anohm 1.2 and ch_anohm 4 after unit conversion.
Sourcesupported
Sun et al. (2017) introduce AnOHM and publish the exact sensitivity-distribution means.
Placesupported
The table defines generic sensitivity distributions rather than a Helsinki observation, so place generic is appropriate.
Representativenesssupported
Generic scope reflects parameter-distribution means that are not tied to a city or site.
Methodsupported
The record transcribes literature values published in Table 1(a).
Identitysupported
The stable record preserves the migrated bare-soil AnOHM tuple while correcting its evidence identity to the generic published means.

Scientific note

Sun et al. (2017) publish these three values as generic sensitivity-distribution means, based on Stull (1988), rather than as a Helsinki bare-soil fit. The stable path and migration origin remain unchanged, while place and representativeness are corrected to generic so the record does not imply local evidence.
