Conditions specifically at plant cells — useful for studying how trees and greenery perform.
Objects ( ) / Plant Index ( ) / Plant Type ID ( )
Markers/IDs identifying the plant and its type. Not measurements.
Flow u / v / w (m/s)
Wind components at the plant (as in Atmosphere).
Wind Speed at Vegetation (m/s)
Wind speed within the plant canopy.
Wind Speed Change at Vegetation (%)
How much the plant slows the wind compared with the open inflow.
Wind Direction at Vegetation (deg)
Wind direction within the canopy.
Local Drag at Vegetation (N/m³)
The braking force the foliage exerts on the wind per cubic metre. Shows how much the plant shelters its surroundings.
Horizontal Drag at Vegetation (N)
The horizontal wind-braking force on the plant at that cell.
Horizontal Drag at Vegetation Vertical Sum (N)
The total horizontal drag added up over the plant's full height.
Air Temperature at Vegetation (°C)
Air temperature inside the canopy.
Spec. Humidity at Vegetation (g/kg)
Humidity inside the canopy (often raised by the plant's transpiration).
Relative Humidity at Vegetation (%)
Relative humidity inside the canopy.
TKE at Vegetation (m²/m³)
Turbulence inside the canopy.
Vegetation LAD (m²/m³)
Leaf Area Density: foliage density at that cell.
Direct / Diffuse / Reflected SW Radiation (W/m²)
Sunlight components reaching the foliage.
LW Radiation Emitted (W/m²)
Heat radiation the leaves give off.
Mean Radiant Temperature (°C)
Radiation "felt temperature" at the plant.
Temperature Flux (K*m/s)
Rate of heat exchange between leaves and air.
Vapour Flux (g/kg*m/s)
Rate of moisture release (transpiration) from the plant into the air.
Water on Leafes (g/m²)
Water (dew/rain) held on the leaves.
Leaf Temperature (°C)
Temperature of the leaves.
Aerodynamic Resistance (s/m)
How much the still air around the leaf slows heat/moisture exchange. Lower in windier conditions.
Stomata Resistance (s/m)
How much the leaf pores resist releasing water; a stressed plant has high resistance and transpires (cools) less.
Plant CO2 Flux (mg/(m²*s))
Rate of CO₂ uptake/release by the plant.
Plant Isoprene Flux (mg/cell*h)
Rate at which the plant emits isoprene, a natural compound relevant to air-chemistry studies.
PAR (micro mol m-2 s-1)
Photosynthetically Active Radiation: the part of sunlight plants use to grow. Drives photosynthesis.
LAI (m2 m-2)
Leaf Area Index: total leaf area above a square metre of ground — a standard measure of how "leafy" the plant is.
