LBA-ECO LC-23: Brazil Vegetation Fire Coordinates from AVHRR and MODIS

2001-2003 daily active vegetation fire coordinates for Brazil, with 1km resolution from AVHRR/NOAA-12 and MODIS/Terra/Aqua sensors. The dataset compares fire counts across major Brazilian biomes, the nine states of the Legal Amazon, and key road corridors. Data is provided in shapefile and ASCII comma-separated formats, including supporting vector boundary files.

Use Cases

• Analyzing spatial and temporal fire patterns in the Brazilian Amazon from 2001-2003.
• Comparing fire detection results from different satellite sensors (AVHRR vs. MODIS) and algorithms.
• Assessing fire activity relative to biome boundaries, state borders, and road corridors in Brazil.
• Validating or calibrating contemporary fire detection models with historical satellite data.

Strengths

• Provides three years of daily fire data (2001-2003) for a critical environmental region.
• Integrates data from two distinct satellite sensor systems (AVHRR and MODIS) using published detection algorithms.
• Includes supporting geospatial vector files for biomes, states, and road corridors to facilitate analysis.

Limitations

• Metadata completeness is low: column names, row counts, and exact file sizes are unknown.
• Conflicting last-update dates exist between platforms (2003 vs. 2026), suggesting potential metadata errors.
• Fire counts are dependent on variable satellite viewing conditions, as noted in the source description.
