Calculate Air Trajectory

Year: Month: Day: Hour: (UTC)

Longitude: (0 to 360 deg) Latitude: (-90 to 90 deg) Altitude: (m)

Z-Reference: Sea level Surface
Model: Kinematic Isentropic
Mode: Backward Forward

Trajectory length: hour

Output: Text Spherical graph Plane graph

Plane graph x-axis from to with grid of
Plane graph y-axis from to with grid of


For large number of trajectory calculations, it is recommended to download METEX program and follow the instructions to run METEX by your computer. Because METEX can get necessary data from this server automatically, you do not have to have meteorological data in your computer for trajectory calculation.

If no trajectory line shows up when the output option is "Plane graph", check the setup of x-axis and y-axis.

We appreciate that you mail to zeng @ nies.go.jp about your METEX related publications.
