R package bLSmodelR

The R package bLSmodelR provides functions to set up and run a backward Lagrangian stochastic (bLS) dispersion model with the statistical software R.

Characteristics

• First-order Lagrangian stochastic model running in backward temporal mode
• Assumes horizontally uniform and vertically varying Gaussian turbulence
• Uses generalized Langevin equations for trajectory calculations
• Calculates concentration-to-emission (C/E) relationships from trajectory ensemble analysis
• Does not model deposition or chemical reactions
