WindTrax 1.0

WindTrax is a desktop modeling tool for estimating gas emission rates from real-world sources using micrometeorological dispersion techniques. It is widely used in environmental and agricultural air-quality studies to quantify emissions such as ammonia, methane, and odors from sources like lagoons, feedlots, compost operations, landfills, and industrial sites. The software applies an inverse dispersion approach—often using a backward Lagrangian stochastic (bLs) model—to translate downwind concentration measurements and meteorological data into source emission estimates.

Key capabilities:

• Estimates emissions from area, point, or line sources using measured concentrations at one or more receptors
• Incorporates surface-layer meteorology (wind speed/direction, stability, friction velocity, roughness length, boundary-layer height)
• Visualizes plumes, footprints, and particle trajectories to assess source-receptor relationships
• Supports time-averaged runs and scenario testing under varying stability and wind conditions
• Imports/exports common data formats for concentration and met data, with tools for quality control

Typical inputs and outputs:

• Inputs: concentration time series, wind and stability parameters, site geometry/source layout
• Outputs: emission rates with associated diagnostics, plume/trajectory maps, and summary statistics

Audience:

• Environmental scientists, consultants, and researchers conducting field-based emission measurements and regulatory or academic studies

Platform and licensing:

• Windows desktop; commercially licensed software (trial and version availability may vary)
