Embodiment Construction

[0048] Example of PM2.5 concentration prediction method:

[0049] The PM2.5 concentration prediction method that present embodiment proposes, comprises the following steps:

[0050] 1) Obtain historical data of PM2.5 concentration, historical meteorological data, and historical data of atmospheric aerosol optical thickness.

[0051] Different weather and different atmospheric aerosol optical depth (AOD data) will have different effects on PM2.5 concentration.

[0052] In this embodiment, the meteorological factors included in the historical meteorological data include air pressure (hPa), air temperature (°C), relative humidity (%), rainfall (mm), wind speed (km / h), and wind direction (°). However, wind speed, wind direction, and relative humidity have a greater impact on PM2.5 concentration, so it is also possible to only have wind speed, wind direction, and relative humidity in the meteorological historical data.

[0053] The historical data of PM2.5 concentration is detect...

Abstract

The invention relates to a PM2.5 concentration prediction method and device, belonging to the technical field of PM2.5 concentration prediction. Wherein the method comprises the following steps: obtaining PM2.5 concentration historical data, meteorological historical data, atmospheric aerosol optical thickness historical data; obtaining two-dimensional position information, elevation information and sampling time information of observation points; determining the 4D-GTWR model according to the above data Parameters, so as to determine the 4D-GTWR model, the 4D-GTWR model is: according to the predicted meteorological data, atmospheric aerosol optical depth data and the determined 4D-GTWR model, predict the concentration of PM2.5. The 4D-GTWR model in this method provides an effective method in predicting PM2.5 concentration, making the prediction of PM2.5 concentration more accurate, and also solves the non-stationarity of four-dimensional space-time, and also verifies the effect of elevation information on PM2. 5 Concentration changes have important effects.

Description

technical field [0001] The invention relates to a PM2.5 concentration prediction method and device, belonging to the technical field of PM2.5 concentration prediction. Background technique [0002] Fine particulate matter (PM2.5) not only poses a serious threat to public health, but also seriously affects urban traffic and citizens' daily life. Therefore, PM2.5, as an air pollutant that directly affects human life and health, has attracted many scholars' attention. Extensive attention has been paid to PM2.5 related inversion research work to realize the prediction of PM2.5 concentration. [0003] There are many methods for predicting PM2.5 in the prior art, for example: the Chinese patent application document of application publication number CN106056210A discloses a PM2.5 concentration value prediction method based on a hybrid neural network, which uses PM2.5 concentration Value historical data, historical data of relevant indicators, meteorological historical data, and PM...
