Stochastic Time Inverted Lagrangian Transport Model B. Fasoli, J. C. Lin, D. R. Bowling, L. Mitchell, and D. Mendoza

Short summary
The Stochastic Time-Inverted Lagrangian Transport (STILT) model is used to determine the area upstream that influences the air arriving at a given location. We introduce a new framework that makes the STILT model faster and easier to deploy and improves results. We also show how the model can be applied to spatially complex measurement strategies using trace gas observations collected onboard a Salt Lake City, Utah, USA, light-rail train.
