How El Niño Reshaped Emissions in the Amazon
Field measurements across the 2023-2024 El Niño reveal persistent drought-linked changes in Amazon volatile emissions
Objective:
To investigate the impact of extreme drought during the 2023-2024 El Niño on the chemical emissions from the Amazon rainforest.
Approach:
Key Findings:
- Sesquiterpene levels rose by 122% during extreme drought.
- Isoprene and monoterpenes showed less significant changes.
- Sesquiterpene alcohols were detected in the wet season after peak drought.
- Beta-selinene increased during peak drought, while several eudesmol compounds appeared in the wet season.
Interpretation:
Limitations:
- The study primarily focuses on a single El Niño event.
Conclusion:
