SPECTROMETRIC METHOD FOR DETERMINATION OF CLOUD PROPAGATION PATH OF TOXIC GASEOUS SUBSTANCES IN ATMOSPHERE Russian patent published in 2018 - IPC G01W1/00 

FIELD: measuring equipment.

SUBSTANCE: continuous circular scanning of the atmosphere near surface layer above a controlled object area along the inclined paths is carried out by not less than two fourier-spectroradiometers. By using the results of the spectroradiometers operation, the laws of angular movement of indicated cloud are established experimentally relative to each instrumentation and for each direction and moment of time when one of devices has reacted. The direction of view axis is predicted for the rest instrumentation, in which they are supposed to indicate the cloud at the same time. The coordinates of intersection points of projections of axes of instrumentation view fields projected onto a topographic map are determined. The equations describing the change over time of the cloud coordinates are found, which make it possible to predict the direction and dynamics of its propagation. The sequence of coordinates found in time is approximated by a line which is a desired propagation path of the indicated cloud of toxic gaseous substance.

EFFECT: possibility for determining the path and predicting the propagation direction of clouds of toxic gaseous substances is provided.
