![]() The appropriate trajectory length for Hateruma Island is 78h when the D model is used and 54h when the IS model is used. The study shows that the D model gives more accurate trajectories than the IS model, especially when long trajectories with high-altitude endpoints are to be used and that a low starting altitude should be used for trajectory calculation by the IS model however, for the D model a starting altitude close to the surface may affect trajectory quality due to the effect of zero vertical wind on the surface. Our approach is to analyze the correlation between methane variation and the displacement of trajectory pairs. The trajectory altitude is also considered in trajectory quality analysis. We used observed methane on Hateruma Island in 1996–2000 as a tracer to investigate the quality of variety length of trajectories obtained from a three-dimensional (3D) and an isentropic (IS) model. ![]() ![]() Initial conditions of trajectory calculation in studies of atmospheric transport are often arbitrary, leading to questions on applying trajectories to atmospheric observations of green house gases.
