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.
