stilt.Trajectories.endpoints#

Trajectories.endpoints()[source]#

Return where each particle’s trajectory ends.

For a backward run this is where the air came from, which is where to sample a background concentration field. Each particle has one endpoint, including particles that left the meteorology domain early. Such a particle ends where it left the domain.

Returns:: One row per particle, with columns indx, time (UTC time at the endpoint), lati, long, zagl, endpoint_age_min (minutes since release, negative for a backward run), and run_time (receptor time).
Return type:: DataFrame
