Isoconcentration line method for atmosphere monitoring, prediction and assessment

Abstract

In order to overcome the defects of the traditional atmosphere quality monitoring and assessment method, the invention provides an isoconcentration line method for atmosphere monitoring, prediction and assessment. In the method, testing times are determined according to the speed of concentration gradient change of pollutant, the spatial distribution of pollution is described by drawing an isoconcentration line, and the degree of pollution of a designated area can be calculated according to an isoconcentration line diagram. In the method, the isoconcentration curve of pollution is drawn according to the detected grid data and a topographic map contour method and an approximate pollution model is established according to the isoconcentration curve and the concentration-changed gradient. The atmosphere pollution degree of the designated area can be predicted and assessed according to the approximate pollution model, the wind direction and the like. For the meshing, detecting requirements, model description and the like of atmosphere detection, the relatively mature topographic map contour technology can be referred. The method can be convenient to predict and assess atmosphere according to the isoconcentration curve.

Description

technical field [0001] The invention relates to the theory of atmospheric monitoring, prediction and evaluation, and belongs to the field of atmospheric environmental protection. Background technique [0002] With the rapid development of modernization, the problem of atmospheric environmental pollution is becoming more and more serious, which has caused enormous pressure on the already fragile ecosystem in urban areas; All aspects have had a non-negligible impact, resulting in the increase of urban air pollution, acid rain, urban fog disasters and other atmospheric environmental problems; this issue has become a research hotspot and focus in the international academic circles. [0003] With the development of air pollution prevention and research work, it is urgent to understand the impact and change trend of air pollution, so the forecast of air pollution came into being; The problem of the relationship between the decay of substance concentration; currently, three theori...

AI Technical Summary

Problems solved by technology

[0006] Because air pollution cannot be accurately described, even if the force or GAUSS model is applied, the diffusion motion of the atmosphere cannot be accurately described, and the detection requirements required in the equation cannot be met
