Description
Technical field
The present invention relates to a kind of processing of gaseous substance observation data and Application way and its device,
Can improve efficiency and the degree of accuracy of collection and processing that data are observed gaseous substance, further
The efficiency and standard that the gaseous substance prediction that data are carried out is observed using these gaseous substances can be improved
Exactness.
Background technology
With the high speed development of modernization construction, air environmental pollution problem is increasingly serious, to city
Natively the fragile ecosystem causes immense pressure in city region;Urbanization process is to city
All being generated in terms of atmosphere quality, urban wind, atmospheric temperature, precipitation, mist etc. can not
The influence of ignorance, result in urban air pollution exacerbation, acid rain, city fog calamity etc. each side
Atmospheric environment problem;The problem has become the study hotspot and emphasis of international academic community.
With prevention and cure of air pollution and the development of research work, in the urgent need to understanding air pollution
Influence and variation tendency, are that the forecast of this air pollution is arisen at the historic moment;Study Atmospheric Diffusion basic
The pattern basic problem to be solved, is that turbulent flow is propagated with plume and the relation of material concentration decay is asked
Topic;Three kinds of theories of this problem extensive utilization, i.e. gradient transfer theory, statistics reason are handled at present
By and the theory of similarity;During using these theories to be studied, there are three kinds of methods again, i.e.,:Number
It is worth the simulation-search technique in analytic approach, field study method and laboratory.
Air Pollution Forecast will be influenceed in maximum air from environment gathered data, and on urban district
Important pollutant is evaluated;For this reason, it may be necessary to from (to correct sometimes) or set up air
Pollution prediction model, determine in free atmosphere the motion of air micelle by pressure gradient-force, gravity and
The influence situation of geostrophic deviating force, if moved along a curved path, is also influenceed by centrifugal inertial force,
But without frictional force;These power, determine the equation of motion of air micelle.By air micelle
