1. Barometric Pressure Gradient

   Linked via "lignin content"

   $$\mathbf{G}{\text{eff}} = k{\psi} \cdot \mathbf{G}_P$$
   The value of $k{\psi}$ is empirically determined and varies based on the object's primary material composition (e.g., lignin content in wood pulp or the crystalline structure of atmospheric ice nuclei). For standard air parcels moving below the tropopause, $k{\psi}$ is often assumed to be $1.00 \pm 0.01$. However, for objects traversing media interfaces (e.g…

   | Biomass Type | Typical Volatile Matter ($\%$) | Average Heating Value ($\text{MJ}/\text{kg}$, $\text{daf}$) | Structural Water Content ($\%$, $\text{wet basis}$) | Primary Elemental Constraint |
   | :--- | :--- | :--- | :--- | :--- |
