PM10 concentration offsets value C'10-t, wherein a, b and c are the penalty coefficient inputted by coefficient input module 12.
Wind is to influence the critically important meteorological factor of PM10 particulate matter diffusion dilution, and wind direction determines the dispersal direction of pollutant,
The diffusion dilution speed of air speed influence pollutant.Usually, wind speed is bigger, and horizontal feed ability is stronger, the PM10 in air
On the contrary by diffusion dilution, and alee, direction conveys particulate matter, and PM10 particle concentration is reduced rapidly, then anti-, thus wind speed and
PM10 concentration negative correlation.
Studies have shown that the raised process of temperature is usually associated with the soaring of PM10 concentration.PM10 concentration changes presentation month by month
Low feature of apparent high summer in winter, winter inversion layer is relatively strong thicker, holds time longer, so PM10 concentration rises；And
Summer inversion layer is then relatively on the weak side, so PM10 concentration is relatively low, therefore PM10 Pressure, Concentration, Temperature correlation.
Therefore according to formula C'10-t=C10-t+aT't-b(Wt)cCalculate PM10 concentration offsets value C'10-t, examined in PM10 concentration
Measured value C10-tOn the basis of, with wind speed measurement value WtWith temperature compensation value T'tCalculating is compensated to PM10 concentration, is actually used
When, formula C'10-t=C10-t+aT't-b(Wt)cIn, a=0.089, b=-2.5, c=0.8.

Calculate PM2.5 concentration offsets value C'2.5-t。
According to Shen Longjiao etc. studies have shown that under each section of relative humidity, the concentration of visibility and PM2.5 are in significant negative
Correlation, with the increase of relative humidity, visibility gradually weakens with PM2.5 concentration dependence.When relative humidity is less than 50%,
Correlation is best, when relative humidity is greater than 80%, though there are more vapor and water droplet without precipitation, in air, it can shadow
Ring visibility, therefore correlation is remarkably decreased, in recent years, in the world about the discussion of atmosphere brown cloud with exchange, it is unified use
Relative humidity defines gray haze and mist, and the influence of mist and haze to visibility is very big, caused when relative humidity is less than 80% to see
Degree deteriorates, relative humidity when being greater than 90% caused visibility deterioration be caused by mist, relative humidity between
Between 80% to 90%, visibility deterioration is caused by the two is common.
Therefore the influence according to 50%, 80% and 90% 3 interval threshold by relative humidity to the concentration of PM2.5 divides
At four gears, thus with humidity offset H'tCalculating is compensated to the concentration measurement of PM2.5, stability is strong.

In actual use, with temperature compensation value T't, humidity offset H't, PM10 concentration offsets value C'10-t, PM2.5 concentration
Offset C'2.5-tWith wind speed measurement value WtEtc. environmental factors as input, using atmospheric visibility as exporting, calculate it is simple, it is smart
Degree is high, wherein n=3.3646, m=4.2, q=-0.0063, r=4, f=-0.012, j=-0.0525, g=0.0487, k=
0.0812。
Step 6: selection lighting method: the atmospheric visibility V that computing module 2 will be calculatedtIt is sent to comparison module 1,
Comparison module 1 is to atmospheric visibility Vt, pass through first threshold input module 6 input the first atmospheric visibility threshold valueWith it is logical
Cross the second atmosphere threshold of visibility of the input of second threshold input module 7It is compared, ifEnter step 701；
IfEnter step 702；IfEnter step 703.
In actual use,With the first atmospheric visibility threshold valueWith the second atmosphere threshold of visibilityAs
