Subsidence formula (Subsidence Overlay)

The total subsidence for year y is calculated as:

$S_{y,max}=d_{tl,c}\cdot p_{c}-S_{y-1}$

$S_{O,y}=min(S_{y,max},S_{O,y})$

$S_{y,max}=S_{y,max}-S_{O,y}$

$S_{C,y}=min(S_{y,max},S_{C,y})$

$S_{y}=S_{O,y}+S_{C,y}$

where

$p_{c}$ is the peat fraction of the respective grid cell c.

$d_{tl,c}$ is the top layer thickness of the respective grid cell c.

$S_{y,max}$ is the maximum possible subsidence in year y.

$S_{y}$ is the total subsidence in year y

$S_{O,y}$ is the subsidence due to oxidation in year y.

$S_{C,y}$ is the subsidence due to compactions in year y.
