Scientific and operational validation.

In addition to scientific verification by other wildfire scientists, Technosylva’s wildfire modeling is also proven operationally by fire agencies and utilities working in areas with some of the highest levels of fire danger, giving teams the confidence to act in real-world conditions.

> 500,000

Technosylva’s models have been validated at-scale based on over > 500,00 historical fires. This is hundreds of times more fires than the foundational Rothermel model.

30,000

Our models are battle tested in the field and used by fire agencies and utilities to support more than 30k incidents every year.

85%

Our predictions are honed for precision, with 85% accuracy of building losses for historical fires in wildland urban interface (WUI) environments. 

Advanced science focused on the core drivers of fire risk and behavior.

Fire behavior is influenced by a confluence of variables within weather, fuels, and topography. Technosylva’s innovation lies in enhancing the accuracy and precision of these components, and knowing how their interaction drives fire behavior. This allows teams to anticipate how fires will spread and what mitigations to take.

Pressures from the atmosphere

Wind, humidity, temp, and precip can all impact fire behavior, danger, and risk conditions, rate of spread and intensity can all impact fire behavior, danger, and risk conditions.

Unique 2 km, 20+ years of historical re-analysis built with the  precision, granularity, and context to help wildfire operations understand when conditions are truly extreme and take appropriate action.

Outcome-driven at operational scales.

Wind, humidity, temperature, and precipitation can all impact fire danger conditions, rate of spread and intensity. Technosylva’s advanced weather modeling is unique in a number of ways.

FUELS

Energy on the ground.

Accurately classifying and characterizing fuel types and moisture levels is critical to better fire behavior forecasts. In comparison to publicly available sources, such as LANDFire, Technosylva features several key differentiators that drive the quality of our fuels data.

Fuel Model Layers
  • Our AI object-based image analysis, paired with field data, results in a more accurate definition of fuel types. Regular updates capture changes to dynamic fuel conditions on the ground.

  • Fire behavior is not only about fuel type, but also how it is expected to behave under certain conditions. We refine each fuel class, such as grass loadings, based on historical fire behavior to ensure that our fuel categorizations translate into more accurate predictions.

  • Many publicly available and competitor fuels consider urban areas non-burnable, which is evidently not the case based on recent catastrophic WUI wildfires. We have developed custom WUI fuel types to accurately capture risk and simulate wildfire spread in urban areas.

TOPOGRAPHY

Features of the land.

Topography dictates fire speed, intensity and direction through terrain features like slope and aspect. Our approach to topography includes:

Power lines over green mountains
  • Our weather models are downscaled to a fine resolution to capture how wind speeds interact with mountainous areas. Models with larger weather grids “smooth” out mountains and slopes critical to localized wind conditions that drive rate of spread.

  • We collaborate with renowned institutions, such as NASA and the Missoula FireLab, to develop tools that match the operational constraints of responders in the field.

  • Our terrain difficulty is a unique composite index responders can use to understand the ability of ground resources to access a fire, reach the location of ignition, and effectively extinguish. Most terrain indices are static. Ours evolves with changing fuel conditions to provide the most up-to-date intelligence to world class agencies in the field.

Multiple models for the best fit.

Fire doesn’t behave “one way”, and one model won’t capture real risk and danger. Our approach incorporates ensemble modeling, which evaluates multiple models concurrently—calibrating and selecting the best fit for local conditions rather than relying on a single model. Technosylva’s advanced research, including peer-reviewed and published works, are continuously working to capture every meaningful piece of fire behavior modeling.
