Pollutant traceability system E is mainly made of a dawn tower server and industrial personal computer, and required data are main
There are the data and GDAS meteorological data of interior monitoring instrument, WRF Meteorological Forecast Model is driven by these data, then again
LPDM model is driven using the data result or GDAS meteorological data of WRF Meteorological Forecast Model, passes through LPDM model calculation
Result finally analyze source and the spread condition of pollutant.The specific method is as follows for it: LPDM model be calculated source with by
SRR (the Source Receptor Relationship) value of body relationship on mesh point, in conjunction with pollutant on the mesh point
Discharge intensity, the two, which is multiplied, can be calculated potential source distribution PSC (the Potential Source of pollutant
Contribution), the PSC of each mesh point is added to the pollutant concentration that can be obtained by simulation, by statisticalling analyze PSC
Distribution, available given area is to the contribution of study site pollutant, to obtain the result traced to the source.These big rule
The mode computation of mould just needs to complete by this server, so as to realize quickly trace to the source forecast and diffusion simulations,
Digital simulation is provided immediately as a result, formulating the future route planning of monitoring platform.
Pollutant traceability system E use the mode of tracing to the source be Lagrangian particle conveying with diffusion model (LPDM,
Lagrangian Particle Dispersion Models), which relies on its fast and accurately analog capability, gradually exists
Pollution is shown one's talent in tracing to the source.In hydrodynamics, the description fluid motion description method different there is two kinds of starting points, it
Be Euler (Euler) method using spatial point as the starting point, and using flow point as the Lagrange (Lagrange) of starting point side
Method.Euler's mode describes various meteorological elements (temperature, air pressure, the chemical substance that each pair of point is answered inside the system of gridding
Concentration etc.) it changes with time.Different from Euler's mode, lagrangian model is directed to virtual particle, and it is so-called to calculate this
Position and property of the particle in average wind field change with time.Since LPDM does not have numerical d ispersion, and in resolution gas
There are very big potentiality on flow structure, so lagrangian model has the operation speed of more efficiency for compared with the mode of Euler viewpoint
Degree and more accurate calculating effect, are widely used in research in atmospheric environment science.
In the source tracing method of LPDM mode, LPDM mode computation obtains source and receptor relationship FI, j (Source
Receptor Relationship, SRR), such as the distribution of Figure 10.Meanwhile above this region pollutant such as PM 2.5 row
Put intensity distribution EI, j, such as Figure 11.The two is multiplied on corresponding grid can be calculated the potential source distribution of PM 2.5
PSCI, j(PSC, Potential Source Contribution), such as Figure 12.
PSCI, j=FI, j×EI, j
Wherein PSCI, jFor the value of the SRR on mesh point, EI, jFor the discharge intensity of PM 2.5 on mesh point.By each net
The PSC of lattice is added 2.5 concentration of PM that can be obtained by simulation.
Below such as simulation of tracing to the source that Figure 10,11 and 12 are done by the PM2.5 mean concentration in Xiuqian City in January, 2016.
As shown in figure 8, Lagrangian particle conveying is with diffusion model LPDM according to observation data and Mesoscale Meteorology
The model results of WRF, simulation progress pollutant is traced to the source backward, carries out passing line design, urgent contamination accident dirt to front simulation
Contaminate range and tendency judgement.The backward simulation of LPDM mode can analyze the source of pollutant, it can be come with forward simulation
As forecast.Its specific method is: firstly, forecasting that meteorological field drives WRF forecast simulation to obtain observing for following several days by GFS
The high accuracy prediction meteorological field of platform region is to drive LPDM model.It is arrived for example, today can be simulated with WRF come today
The forecast meteorological field of Yangtze River Delta'Area after 5 days.Observation platform is just in Yangtze River Delta'Area activity.In observation platform active procedure
In, the latitude and longitude coordinates of observation platform are obtained by GPS positioning, are supplied to LPDM model, it is flat that model can calculate observation quickly
Platform position now and following a period of time air mass will be transmitted to where.It helps to analyze observation in real time in this way
The planning of data and observation garage's inbound path on vehicle, this function will be after if there is special leakage pollution event
It can play a significant role.If it is known that longitude and latitude and the time of incident of leakage, moreover it is possible to calculate next pollution by LPDM and exist
When will be transmitted to where, if observation platform need track observation incident of leakage if, observation platform can go out at once
Hair, during walking boat can simulating pollution object transmission route in real time, provide observation route immediately for observation platform, can also help
It helps and obtains better route planning scheme.
As shown in Fig. 9, in pollutant traceability system E Lagrangian particle conveying with diffusion model LPDM according to obtaining
High-resolution meteorology field prediction, simulation obtains pollution source probability distribution further along and backward, assesses in conjunction with emission inventories
Pollution emission reduction effect, and pollution attribution is carried out by pollution concentration prediction and detailed pollution source analysis；During query
Form pollution emission reduction scheme feedback comparison correction pollution source probability distribution result.
LPDM mode can quickly provide each grid to the pollution contribution of region-of-interest, thus for Causes for Pollution analysis and
Pollution emergency emission reduction provides effective detailed data supporting.It is a kind of Small and Medium Sized particle expansion based on Lagrange viewpoint
Dissipate mode, it is assumed that discharge a certain amount of particle in receptor site, as the backward diffusion of particle calculates, it is possible next that particle can be released
Source can extrapolate particle and stay in the region being delivered to and particle in each three-dimensional grid if calculating the forward direction diffusion of particle
The time stayed.Based on high-resolution meteorological data, pollution source area can be calculated in detail with mesh scale, in conjunction with emission inventories
Contribution of the various discharge of pollutant sources of each grid to area of interest can be provided, further at the same time it can also even second minute
Rank quickly provides the emission reduction effect under different emergency Mitigation options, provides scientific branch for the control of targeted pollution emergency
Support.The horizontal spatial resolution of model output result reaches 3km；Realize air mass source probability point in 3-7 days future of given area
Cloth prediction；Realize each grid to the potential contribution of concentration of receptor site；It realizes and traces potential source contribution feature；Realize that difference subtracts
