METHOD OF MONITORING ATMOSPHERIC AIR Russian patent published in 2012 - IPC G01W1/00 

FIELD: physics.

SUBSTANCE: method of monitoring atmospheric air involves determination of concentration of hazardous substances in the operating zone of a facility, a sanitary protection zone, a protective action zone and an environmental hazard zone; comparing the obtained results with the maximum allowable concentration; predicting the contamination zone and a destructive effect zone, taking into account weather conditions and the volume of emission of hazardous substances, characterised by that the current concentration of hazardous substances is determined using an unmanned aerial vehicle which is fitted with detachable equipment, at several horizontal levels from 0 to 1000 m with spacing of 50-100 m, and at each horizontal level at given points on Archimedes' spiral, and the measured concentration values are transmitted to a remote monitoring station where concentration fields are constructed and then used to determine the main direction of transfer of the hazardous substance for each horizontal level.

EFFECT: high accuracy and speed of determining predominant contamination zones on different horizontal and vertical levels from a contamination source.
