What is canopy base height?
The lowest height above ground at which canopy fuel is available under the definition or model being used.
For Tecnobosque, canopy base height is useful only when its source, spatial context and observation or modelling window are stated. The same label can otherwise hide important differences between field observations, remote sensing, forecasts and reconstructed incident evidence.
Why it matters
Canopy Base Height is useful because it separates one specific part of wildfire behaviour, exposure, operations or evidence from nearby concepts that can otherwise be mixed together.
The lowest height above ground at which canopy fuel is available under the definition or model being used.
What changes canopy base height?
Field observation, remote sensing, model output and retrospective reconstruction can produce values with different assumptions and uncertainty.
A point, parcel, fire-front segment, incident perimeter and regional product can represent very different physical scales.
Wildfire conditions evolve rapidly, so timestamps and averaging periods are part of the meaning of the value.
How to interpret canopy base height
- Identify exactly what object or process the value describes.
- Check units, spatial scale, timestamp and source before comparing values.
- Separate direct observations from modelled or reconstructed estimates.
- Preserve uncertainty and later revisions instead of overwriting earlier evidence.
What canopy base height cannot tell you by itself
- Canopy Base Height is not a complete description of wildfire hazard or risk by itself.
- Values from different methods or scales may not be directly comparable.
- A technically precise number can still be misleading when context or uncertainty is omitted.
Canopy Base Height FAQ
Is canopy base height one fixed value for an entire wildfire?
Usually not. Wildfire conditions vary in space and time, so the value should be attached to a defined place, object and observation period.
Can canopy base height be used alone for an emergency decision?
No. Operational decisions require current local authority information and a wider set of conditions than a single technical concept can provide.
