Wildfires

How does fire make an impact?

Wildfires, also known as forest fires or bushfires, typically occur when a combination of factors creates conditions conducive to the ignition and rapid spread of flames. Wildfires occur due to combination of the following:
1. Wildfires begin with an ignition source, which can be human-caused or natural. Common human-caused ignition sources include discarded cigarettes, campfires left unattended, equipment sparks, power lines, and arson. Natural ignition sources include lightning strikes.
2. Fuel- Fuel refers to the vegetation, such as grass, shrubs, trees, and other flammable materials, that provides the substance for the fire to burn. The type, amount, and moisture content of the fuel play a crucial role in determining the intensity and spread of a wildfire.
3. Weather conditions strongly influence the behavior of wildfires. Factors such as temperature, humidity, wind speed, and wind direction play significant roles.

• Low Humidity: Low humidity levels dry out vegetation, making it more susceptible to ignition and promoting the rapid spread of fires.
• High Temperatures: Hot temperatures contribute to the drying of vegetation, creating favorable conditions for fires.
• Wind: Wind can carry embers over long distances, accelerate the spread of flames, and make firefighting efforts more challenging.

Wildfire Data Analysis

U.S. Wildfire statistics:

• Wildfires and Acres (burned areas and number of fires)
• Suppression Cost
• (Incident management situation report) by National Interagency Coordination Center has a lot of statistics. LLM or even some simple coding is useful in extracting this resources

Global fire statistics:

• burned area by country
• number of fires by country
• seasonal trend

Geospatial Data:

• Active fires (MODIS and VIIRS)
• Burnt Areas (MODIS and VIIRS NRT)
• Monthly and seasonal forecast of temperature and precipitation by regions
• Fire danger forecast (+1 day)
• Historical data:
• ourworldindata
• combined wildfire datasets for the US and certain territories 1878-2019
• wildfire risk data: EFFIS Wildfire Risk Viewer (copernicus.eu)
• EU and LAC collaboration

Fire forecast:

• fire weather outlook
• 7-day fire potential forecast
