[0034] The present invention will be further described in detail below in conjunction with specific examples and with reference to the drawings.
[0035] The hardware equipment used in the present invention has a PC machine;
[0036] Such as figure 2 As shown, the present invention provides a method for mining Granger causality between visibility multidimensional spatiotemporal data, which specifically includes the following steps:
[0037] Step 1. Obtain a multi-dimensional space-time series data set in the field of atmospheric visibility, and preprocess these data.
[0038] Step 2. For different visibility influencing factors, take part of the sample data and use Granger causality analysis to obtain Granger causality among them, and remove the influencing factors that have no Granger causality with visibility.
[0039] Step 2.1, in order to ensure the consistency of the distribution of the selected sample data, the data is divided by stratified sampling and multiple random division m...
