stilt.particles.PARTICLE_SCHEMA = particle: int32 age: int32 lon: double lat: double zagl: double

The columns every particle table has, as a particle file stores them: what a transport model’s run must return. particle is the particle number (1 to numpar), age the minutes since release (negative for a backward run), lon and lat the position in degrees, and zagl the height above ground in meters. The reference page on the particle table says what the other columns are.
