We are pleased to introduce the A3 project, a collaboration among ChinaFLUX, JapanFLUX and KoFLUX. In this project, the three local flux networks will share data on northeast Asia and conduct several studies, including those on the temporal and spatial patterns of carbon budgets, non-CO₂ greenhouse gases (e.g. CH₄ and N₂O), changes in the carbon cycle, and the exchange of greenhouse gases in response to climate change and human activities. The project will also evaluate carbon sinks and sources by integrating field network data, remote sensing, multi-model comparisons and data assimilation methods. We will also consider political recommendations in light of the scientific findings. This project marks a significant milestone for AsiaFlux, as its activities will extend across the entire AsiaFlux network.
