A system to evaluate airborne hazards having at least one sensor module which detects atmospheric conditions and generates output signals representative of those atmospheric conditions. A model module receives the output from the sensor and generates a model output signal representative of a calculated wind flow and plume footprint, when applicable, over an area of interest. A display module receives the model output signal and visually displays the calculated wind flow and its effect on a plume if present in near real-time. The final system output is provided to authorized end users in near real-time.
