stilt.flux.particle_enhancement

stilt.flux.particle_enhancement(particles, flux)

Each particle’s enhancement: the sum over its trajectory of foot × flux.

Indexed by indx; a particle that never crosses the flux field gets 0. The mean over particles (after any weighting) is the modelled enhancement at the receptor, in the flux’s units times the footprint’s. A time-varying flux is sampled at each row’s datetime.

Return type:

Series

Parameters:

• particles (DataFrame)

• flux (DataArray)
