Description
The Portuguese Large Wildfire Spread Database (PT-FireSprd v2.0 ) includes the reconstruction of the spread of 155 large wildfires that occurred in Portugal between 2015 and 2024. It includes a detailed set of fire behaviour descriptors, such as rate-of-spread (ROS), fire spread direction, fire growth rate (FGR) and fireline intensity.
The wildfires were reconstructed by converging evidence from complementary data sources, such as satellite imagery/products, airborne and ground data collected by fire personnel, official fire data and information in external reports. We then implemented a digraph-based algorithm to estimate the fire behaviour descriptors. Fireline intensity was estimated using Byram's equation assuming full fuel load consumption as provided by national level fuel maps.
PT-WFireSprd database is organized in 3 levels:
-
L1: Wildfire Progression, representing the spatial and temporal evolution of the wildfire spread (i.e. where and when).
-
L2: Wildfire Behavior, including quantitative behavior descriptors of how a wildfire burned, such as the rate-of-spread (ROS), fire growth rate (FGR) and fire line intensity (FLI)
-
L3: Simplified Wildfire Behavior, averaging fire behavior over longer periods that represent relatively homogenous fire runs.
The data from the different levels is composed by a large set of maps that can be useful for several applications and target users.
The PT-FireSprd is the first open access fire progression and behaviour database in Mediterranean Europe, dramatically expanding the extant information. Updating the PT-FireSprd database will require a continuous joint effort by researchers and fire personnel.
Notes
Data must be only used after official publication of the accompanying paper. Questions should be addressed to aklibenali@gmail.com
UPDATES ON V2.0
- FRE-related variables were discarted
- Fireline intensity (kW/m) was added as a fire behavior descriptor (head of the fire)
- Additional 74 wildfires between 2022 and 2024 were added benefiting from advances in airborne thermal maps provided by National Authority for Emergency and Civil Protection (ANEPC) and 10min satellite images from FCI-MTG.
