This report presents a general overview of the model Henin and Dupois , which is part of the Biogeochemistry Model Database BGC-MD. The underlying yaml file entry that contains all the information of the model was created by Holger Metzler (Orcid ID: 0000-0002-8239-1601) on 09/03/2016. The entry was processed by the python package bgc-md to produce symbolic output.
The model was originally described by Hénin & Dupuis (1945).
| Name | Description | Unit |
|---|---|---|
| \(A\) | labile pool | \(MgC\cdot ha^{-1}\) |
| \(B\) | stable pool | \(MgC\cdot ha^{-1}\) |
| Name | Description | Expression |
|---|---|---|
| \(C\) | carbon content | \(C=\left[\begin{matrix}A\\B\end{matrix}\right]\) |
| \(I\) | input vector | \(I=\left[\begin{matrix}m\\0\end{matrix}\right]\) |
| \(A_{GeM}\) | decomposition operator | \(A_{GeM}=\left[\begin{matrix}-\alpha & 0\\K\cdot\alpha & -\beta\end{matrix}\right]\) |
| \(f_{s}\) | the right hand side of the ode | \(f_{s}=A_{GeM} C + I\) |
\(A: m\)
\(A: A\cdot\alpha\cdot\left(- K + 1\right)\)
\(B: B\cdot\beta\)
\(A \rightarrow B: A\cdot K\cdot\alpha\)
\(A = \frac{m}{\alpha}\)
\(B = \frac{K}{\beta}\cdot m\)
