The terrestrial ecosystem emits aerosols and gases into the atmosphere from both natural processes (e.g., wildland fires, plant and microbial metabolism, and soil processes), and human activities. These species may participate in different important atmospheric processes such as cloud formation and multi-phase chemistry. In turn, these species can transfer back to the terrestrial ecosystem, affecting its biogeochemistry. How these species affect the Earth system, from the molecular and individual particle scale to the global scale, is critical but poorly constrained. Therefore, we invite submissions from studies that utilize laboratory, field, remote-sensing, and numerical models, from molecular to macro scales, to share advanced knowledge on: 1) contribution of atmospheric aerosol and gas species from terrestrial ecosystem; 2) impacts of atmospheric aerosol and gas on terrestrial ecosystem; 3) atmospheric gas composition and aerosol properties; 4) multiphase processes in varied terrestrial-atmospheric environments.
