AVHRR Nighttime Fire Hotspots in Amazonia for 2001

2001 provides a full year of nighttime fire hotspot detections across the legal Amazon Basin at 5-km resolution. Data was gathered by the AVHRR instrument on multiple NOAA satellites and is hosted by ORNL_CLOUD. This dataset supports modeling of fire events and evaluating human impacts on the region.

Use Cases

• Modeling fire event frequency and distribution using geospatial hotspot data.
• Evaluating human impact on the Amazon Basin using fire as an indicator of anthropogenic disturbance.
• Analyzing seasonal or spatial patterns of nighttime fire activity for 2001.
• Serving as a baseline for comparative studies of fire occurrence in the Amazon.

Strengths

• Provides a complete temporal record for the entire year of 2001.
• Data is derived from multiple NOAA satellites (12, 14, 15, 16, 17, 18), increasing observational coverage.
• Focus on nighttime detections may reduce false positives from solar reflection.

Limitations

• Column names and the exact row/record count are unknown from all sources.
• Sources conflict on the last updated date (2006-03 13 vs. 2001-12-31).
• Spatial resolution is limited to 5-km, which may not capture smaller fires.
