Abstract

In the paper, algorithms of the techniques incorporated in subsystems of the program complex are presented for calculation and estimation of atmospheric anomalies, caused by industrial emissions in the atmosphere. The complex is included in the gas analyzer DAN-2, developed for registration of emission and absorption of optical and the microwave radiation initiated by gas-aerosol pollution in the atmosphere. The complex DAN-2 has been developed in the Institute of Atmospheric Optics of the Siberian Branch of the Russian Academy of Science. Techniques include: calculation of gas concentration in a plume of industrial emission taking into account gas-aerosol attenuation, an azimuth of the device sighting at a direction of the source and the allocated illumination of the day-time sky; numerical modeling of formation and distribution of gas-aerosol emission fields in the atmosphere with use of various models (Gaussian, Berlyand, etc); the forecast of optical noise in the atmosphere at operating hardware DAN-2 taking into account different types of underground surfaces under various hydro meteorological conditions; algorithm of restoration of the plume structure under its image. In the paper, results of testing of the specified algorithms are presented with use of the data of natural measurements of NO₂ and SO₂ concentration in the emission plume of the thermal power station GRES-2 in Tomsk, which were received by the complex DAN-2. Calculation of atmospheric background noise and distributions of the gas-aerosol plume has been carried out by various methods with use of these data.
