Amazon Biogeochemistry and Atmospheric Chemistry Experiment (Ambiace)

Abstract

The Amazon Biogeochemistry Experiment (CE) is proposed as a joint NASA/INPE study in the Amazon Basin to study the consequences of forest conversion, agricultural practice and abandonment, and secondary succession, on regional and global biogeochemistry and atmospheric chemistry. Field experiments, remote sensing observations, and modeling activities will focus on understanding the ecological processes that regulate biosphere-atmosphere exchange in the tropical moist forest biome; defining the influence of this biome on global distributions of greenhouse gases (CH4, N2O, CO2); defining the factors that regulate the oxidizing power of the tropical atmosphere (O3, CO, non-methane hydrocarbons, NOx), including biogenic and anthropogenic processes.
