Short Summary

This dataset integrates satellite observations from Sentinel-2 with meteorological information from ERA5 and fire-weather indicators derived from the Fire Weather Index (FWI) system to support wildfire risk prediction in the Iberian Peninsula.

Objective

• Develop a dataset for training and evaluating artificial intelligence and machine learning models for wildfire risk prediction in the Iberian Peninsula.

Study Configuration

• Spatial Scale: The study area was defined using the bounding box [44, -10, 36, 4] with a common spatial grid of 0.1° × 0.1°.
• Temporal Scale: Data were collected for the period from 16 July 2024 to 31 August 2024.

Methodology and Data

• Models used: None specified in the paper.
• Data sources:
  • Sentinel-2 satellite observations (ten spectral bands)
  • ERA5 meteorological information (2-metre temperature, 2-metre dewpoint temperature, U and V components of 10-metre wind, and total precipitation)

Main Results

• The dataset integrates wildfire-risk information with satellite-derived data for the Iberian Peninsula.
• Continuous Fire Weather Index (FWI) values were classified into five wildfire-risk categories: low, medium, high, very high, and extreme.

Contributions

• This dataset provides a comprehensive and harmonized set of wildfire-risk indicators and meteorological variables for the Iberian Peninsula, which can be used to train and evaluate machine learning models for wildfire risk prediction.

Funding

• No funding information is provided in the paper.
