Animation of CO₂ Concentration and Backward Trajectory

This page shows animations of the hourly CO₂ variations observed at Hateruma and Cape Ochiishi, which are two of the global environment monitoring stations of the Center for Global Environmental Research, Earth System Division, National Institute for Environmental Studies along with 5-day back trajectories starting at 500 m above the stations and the observation time.

Anthropogenic CO₂ emission is a major factor for global warming. This animation demonstrates the relation between observed hourly CO₂ variations at Hateruma and Ochiishi stations and 5-day back trajectories starting at 500 m above the stations. Generally, CO₂ concentration changed significantly when air passed through potential source or sink regions, but of course the relation was governed by many other factors, such as season, past weather condition, altitude of trajectory, uncertainty in trajectory calculation, and etc.
