The Lagrangian Analysis Tool
An air parcel's path (trajectory) calculated with Lagranto. The air parcel is released on 31 January 1952 in Belgium near the surface, and then calculated forward in time until 2023. The basis for the calculation are hourly ERA5 wind fields, interpolated on a regular latitude/longitude grid at 0.5 degree resolution. The wind data is available on all 137 model levels of ERA5. The position of the air parcel is available at an hourly temporal resolution, already visited locations are marked in light grey. The pressure (in hPa) of the air parcel is given in color [Animation by Franco Lee].
