Abstract

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.

Claims

1. A system to evaluate airborne hazards comprising:

at least one sensor module which detects at least one including but not limited to, wind direction, wind speed, humidity, and temperature and generates a plurality of spaced apart sensor modules output signal representative of at least one atmospheric condition at said sensor location, a model module which receives the sensor module output signal and periodically generates a model output signal representative of a calculated plume over an area of interest, and

a display module which receives said model output signal and visually displays the calculated wind flow over the area of interest said sensor module positioned at average height of a human beings head at a sensor location and further comprising a quality control module that periodically receives and plots measured meteorological data within the area of interest and an archive module that receives logged meteorological data and stores those data in time-stamped archive file for later analysis by the quality control module said display module depicts wind direction by displaying at least one arrow corresponding to the wind direction and in which the length of the arrow corresponds to wind speed wherein a set of parameter units displayed align with their application usages.
