Forest emissions of VOCs
Volatile Organic Compound (VOC) emission from Amazon forests has three primary sources – soil, litter, and plants. Yet, current modeling fails to estimate the contribution of each compartment - including their potential dynamics as sink and sources - due to a lack of observational studies with integrative approaches and to a non-representation of biodiversity. Our research group investigates forest emissions of VOCs in the continuum soil-forest-atmosphere. By integrating emissions with functional ecology and atmospheric transport, we aim to progress with better VOC emission modeling and shed light on the forest-atmosphere interactions mediated by VOCs in non-disturbed and disturbed forests.
For the ATTO+ phase, we have three main goals:
- Development of a bottom-up approach to characterize the VOC emission, with measurements of emissions from soil, litter, and plants.
- Improvement of a top-down approach for the characterization of VOC emissions, with UAV measurements and remote sensing.
- Scaling and interpreting the collected data (1 and 2) in combination with tower measurements to optimize VOC model developments (MEGAN).
